Since the occurrence of the new coronary pneumonia epidemic, statistics show that the incidence of lung cancer has increased significantly! At the same time, the incidence of other types of cancer such as skin cancer has declined. Is the increased incidence of lung cancer due to new coronavirus infection? Such speculation is unreasonable, because there is no such basis at present, indicating that the new coronavirus can directly induce cancer, so what is the cause? The discussion here is as follows. Why did the new crown epidemic increase the incidence of lung cancer and reduce the incidence of other types of cancer? The reasons behind are worrying. The following factors may lead to the increase of confirmed cases of lung cancer during the new crown epidemic: 1) There are more people who went to the hospital to check for lung symptoms due to the epidemic. I have an example in the old village of the author. There is an old man in the village during the Chinese New Year. Symptoms of fever and cough appear. If you do not catch up with the epidemic, you may get a shot at the village health center and take some medicine to solve it. However, due to the epidemic situation, the village cadres demanded quarantine and went to the designated top three hospitals to make a clear diagnosis and found that it was not pneumonia or lung cancer. Although it was discovered, it was in its late stages, and the treatment died shortly afterwards. In the New Crown Epidemic, the symptoms and inspections of New Coronary Pneumonia are being promoted in various places. Residents and communities are particularly vigilant to people with related symptoms, so they should seek medical treatment in time when similar symptoms may appear, and many early cancer symptoms may not be obvious. Like lung cancer, it may be similar to the symptoms of ordinary pneumonia. Usually, many people may buy their own medicine and take the symptoms to improve without paying attention. 2) In the early stage of the epidemic, there are more people undergoing lung CT examination in the hospital. Because of the shortage of new crown reagents, “false negatives” and “false positives”, many hospitals will follow the guidelines combined with imaging examinations, especially chest CT for diagnosis , This will naturally increase the chance of fever, cough and other patients taking CT. Because most of our physical examinations and common lung infections usually take X-ray chest radiographs, its resolution is low, and lung cancer is generally not screened. It is basically late when it is found. The sensitivity of CT is 4-10 times that of X-ray, and the possibility of screening for lung cancer is greatly improved, which will naturally increase the probability of lung cancer, breast cancer and other chest tumors found. 3) During the epidemic, many people are reluctant to go to the hospital if it is not fever, cough, general people are reluctant to go to the hospital for medical examination during the epidemic, after all, the hospital is a high-risk area during the epidemic, especially the elderly, afraid to go to the hospital because of their low immunity The virus risk is high. So the body is uncomfortable and can tolerate, so that the physical examination is lost, and hidden cancers are not easy to find, resulting in a reduction in the incidence of these cancers. Conclusion Through analysis, we also get inspiration from it: Although the onset of lung cancer is hidden, if we have the awareness of prevention, regular lung CT examination after the age of 40 can greatly improve the early detection rate of lung cancer, and early detection of lung cancer treatment And the prognosis is undoubtedly very important. The same is true for the discovery of other cancers. If you feel unwell, you can’t bear it. Going to the hospital to see a specialist to find out the cause is very important. In the end, whether it is the neocoronavirus pneumonia or lung cancer and other cancers, we are the enemies we must fight together. In life, only by improving lifestyle, quitting smoking, taking good protection, and going to the hospital for standard diagnosis and treatment as soon as possible if you have uncomfortable symptoms, can you find and treat early.

. . . . . . . According to the website of Inner Mongolia Bayannaoer City Health and Health Commission website, on July 5, 2020, a herdsman in Wengen Town, Wulatzhong Banner, Bayannaoer City, in Ulaan During the visit to Tezhongqi People’s Hospital, the expert team confirmed the case of bubonic plague. The patient had been active in the plague epidemic area before the onset of illness. At present, the patient has been isolated and treated in a local hospital, and his condition is stable. To win the plague, you must know this knowledge! ·&Nbsp. . What is plague?  .· . . . . . Plague is a natural epidemic disease. It is a severe infectious disease characterized by rapid onset, rapid transmission, high mortality and strong infectivity. The Class A infectious diseases stipulated in the Law on the Prevention and Control of Infectious Diseases ranks first among 39 kinds of statutory infectious diseases. It is also called “No. 1 disease”. It has caused three pandemics in the world and countless deaths.  . . . . . . . . The determined plague epidemic sites in my country are distributed in 201 counties (cities) in 17 provinces and autonomous regions, covering an area of more than 600,000 square kilometers. With the active plague in the world, 106 cases of human plague were found in Qinghai, Xinjiang, Tibet, Yunnan, Inner Mongolia and other five provinces from 1991 to 1994, with a case fatality rate of 24.5%. ·&Nbsp. . The prevalence of plague .· . . . . Speaking of plague, this ancient infectious disease, which had three pandemics in human history, caused a total of nearly 170 million deaths. The first plague pandemic killed about 100 million people, and the second plague, the medieval “black death”, caused about 50 million deaths. It wasn’t until the 1970s that the plague epidemic was controlled and spread out. From the 1970s to the 1980s, about 1,000 plague cases were reported worldwide every year. Since the 1990s, the plague epidemic situation has been on the rise. For example, from 1989 to 2003, 38,310 cases of plague were reported in 25 countries around the world, of which 2,845 died. From 2010 to 2015, a total of 3248 cases of plague were reported globally, including 584 deaths.  . . . . The Law of the People’s Republic of China on the Prevention and Control of Infectious Diseases stipulates that the plague is a Class A infectious disease. There are only two Class A infectious diseases in our country, and the other is cholera.  . . . . There is another name for the plague, which everyone must have heard of, and that is the Black Death. A symptom of this epidemic is that many black spots appear on the skin of patients, so this horrible plague is called “black death”. ·Types of plague .·1. Bubonic plague: Pathogens transmitted through the bite contact route will first invade the lymph nodes, causing lymph node swelling, necrosis and abscesses, most of which are inguinal lymph nodes. This process is called bubonic plague. 2. Septicemic plague: caused by pathogenic bacteria invading the bloodstream to multiply and form bacteremia and sepsis. This process is called septicemic plague. High fever (39-40°C) may occur, and small bleeding spots appear on the skin and mucous membranes. If not rescued in time, it may die within 2-3 days. 3. Pneumonic plague: Pathogens accumulate in the lungs through the bloodstream and multiply in alveolar macrophages to cause pneumonia. This process is called pneumonic plague. Pneumonic plague is secondary to bubonic plague and septicemic plague. The patient developed high fever and expectoration, with a large amount of Yersinia pneumoniae in the sputum. Patients or animals suffering from pneumonic plague can spread pathogenic bacteria through close-range airborne droplets, leading to the spread of plague. Most of the sensitive animals and people infected with the disease died within one week after being infected with Yersinia pestis. ·&Nbsp. How did the plague spread?  .·1. . Source of infection . (1) Plague infected animals. Animals naturally infected with plague can be used as the source of human plague. The main source of infection is rodents such as rodents and drought.
The new crown epidemic situation currently exceeds the 10 million mark in the world, and the number of confirmed cases in the United States accounts for about a quarter of the total, ranking first in the world. More than half a year has passed since the discovery of the new crown epidemic. Although my country has achieved periodic results in epidemic prevention and control, other countries abroad are in full swing, and many countries have heard the news of the epidemic rebound! People cannot help but ask, is the New Coronavirus epidemic so severe, is it a “natural disaster” or a “human disaster”? Is the new crown virus epidemic “natural disaster” or “human disaster”? “Natural disasters” often refer to natural disasters, while man-made disasters refer to “human disasters”. The author believes that the Xinguan epidemic is so fierce that there are both “natural disasters” and “human disasters”. (1) The source of the natural disaster virus has not yet been found. As far as the investigation and research of current scientists are concerned, it may be related to bats, or it is more likely to consider natural sources. The early stage of the new crown was caused by “natural disasters” in our country. At first, everyone didn’t understand the virus, how to prevent it, how to kill the virus, how to treat it, it was a black eye. And during the Spring Festival, the world’s largest population migration period, spread quickly. But it was only after the Chinese government and people paid a huge price to control this “natural disaster” to a manageable level. The complexity and cunning of the virus is what we gradually learned in the fight against the virus. This is not controlled by man. This is the “natural disaster” aspect of this epidemic. (2) Although the characteristics of the human disaster virus cannot be controlled, the spread of the new crown epidemic also has “human disaster” factors. China has accumulated rich experience in SARS and this epidemic, and it has been shared with countries all over the world before the global outbreak. However, many countries, especially those in Europe and the United States, have not learned our experience and lessons. Neither government policy nor national mobilization has paid attention to the epidemic like ours, giving the virus an opportunity to break out, so that some countries have already Give up resistance and intend to achieve “natural immunity” at the expense of the lives of the people. Therefore, some people said that they would not copy the homework. As Professor Zeng Guang, the former Chief Scientist of Epidemiology of the Chinese Center for Disease Control and Prevention, said: Western countries have neither learned experience nor learned lessons, which has caused Western countries to make mistakes in response to the epidemic. They have neither early warning nor control, nor have they done Good epidemiological survey! Many countries have begun to pay attention only to the treatment of diseases but not to the spread of diseases, and have not taken effective control measures like China. This is undoubtedly a factor of human disaster. Conclusion The outbreak of the new crown has now reached 10 million, and it has not reached its peak. From the current data, it will continue to grow. This epidemic has given humanity a hard lesson. This is a fierce battle between viruses and humans. Only by minimizing man-made disasters and working together to fight the virus together is the fastest and most effective way to solve the virus epidemic. Countries are currently developing vaccines, hoping to develop effective vaccines as soon as possible, which is an effective weapon against viruses.

According to the latest data released by the Indian Ministry of Health’s official website, the number of confirmed cases of new coronary pneumonia in India has reached about 500,000, and more than 10,000 deaths have occurred. India’s epidemic is getting worse. As a big country with a population of more than one billion people, the number of confirmed cases is increasing so quickly, which is actually very dangerous. But why do you feel that India’s society is functioning normally and there is no mess? The author believes that there are the following reasons: The government’s anti-epidemic measures The Indian government did not fight the epidemic of the “Buddhist system” as some Western countries did. As early as March, the Indian government formulated the strictest national blockade ever, and it was delayed until 6 End of the month. In order to alleviate the bed tension, India established a “train ward” with unique Indian characteristics by referring to China’s “square cabin hospital”, and transformed the currently unused train cars into temporary wards. Although with the escalation of economic pressure, people began to resume production and production, so the epidemic situation began to deteriorate, but the government’s epidemic prevention measures generally have no major problems, the Indian people do not have much opinion on the government. And outbreaks are happening in various countries around the world. The United States is still so powerful that 2.5 million people have been diagnosed, which is five times that of India. There is no riot in the United States. Influence of Religious Belief India is a very religious country, almost everyone believes in religion. Although there are many types of religions that people believe in, such as Hinduism, Islam, Sikhism, etc., almost all religions advocate karma and reincarnation. Therefore, people do not think that the outbreak of the epidemic is a government problem, and may think that it is their own bad karma. Moreover, because conflicts in India due to religious, ethnic, and other conflicts kill many people every year, the deaths caused by the epidemic have not caused much panic in India. The Sino-Indian conflict shifts the sight of Indian nationals. On the evening of June 15, the Chinese and Indian armed forces clashed in the border area, and it was the Indian military that provoked the conflict. It is not excluded that in this way, the Indian government transferred the domestic epidemic situation and the class conflicts caused by the economic recession. At present, nationalism in India is very high, and some people even begin to boycott Chinese goods. This is actually a stupid move. The new crown virus will not disappear because of the public’s distraction. Conclusion Although the epidemic in India is very serious, it has not yet reached the level of causing riots. The new crown virus is the enemy of people all over the world. What is more important now is that we should unite and overcome the difficulties together, rather than provoking and conflicting between countries. All countries should have the concept of a global community of destiny and face the biggest enemy together. And the main contradiction: the new crown epidemic.

A while ago, a new coronavirus was detected in the salmon board in a wave of outbreaks in Beijing, which triggered a big discussion on food safety. Among them, the topic of how to wash the meat was screened. In the end, how should the meat be cleaned before it is fried? In fact, no matter whether the epidemic situation exists or not, this problem needs to be clear and clear in order to be at ease! Of course, in the context of the global outbreak of the new crown epidemic, we still need to mention the problem of virus transmission. Based on the current evidence, this wave of virus transmission in Beijing is likely to be caused by virus contamination of meat products transported through the cold chain. This is another new discovery of the new crown virus vector since the outbreak of the new crown epidemic in China. Since this time the medium of transmission is meat products, in theory, meat products on the market are likely to be contaminated by new coronavirus, and improper handling is likely to lead to the spread of pollution. This also reminds us that how to handle raw meat is also an epidemic prevention and control An important issue under normalization. Why can’t you buy home-made meat with water? The meat you buy home can be cleaned, but it is recommended not to rinse it, the difference is a word, pay attention! First of all, meat is a kind of food that is very easy to breed microorganisms, and the meat we usually buy in life is not sterilized. During the processing process, for example, the knife that cuts raw meat will also have a lot of bacteria contaminating the raw meat. Secondly, in fact, the National Health and Health Commission has clearly given the answer earlier. On June 18th, the National Health and Health Commission released the “Normal Risk Prevention and Control of New Coronary Pneumonia Outbreaks in Key Units in Key Areas in Summer and Summer” on the official website. The “Related Protection Guide” mentions that households should pay attention to the hygiene of food preparation, especially after handling raw meat, poultry, aquatic products, etc., wash hands with soap and running water for at least 20 seconds, and do not rinse raw meat directly under the tap Pathogens on products and raw meat may spread everywhere with water droplets and spread to sinks, operating tables, stoves, utensils, etc., causing cross-contamination. Therefore, it is recommended not to rinse the meat you bought home directly. You should use a special container to soak the rinse, put the meat in the water, and avoid washing the bacteria to other places. The surface of the raw meat is clean, can it not be washed? Yes! Although there may be bacteria on the surface of raw meat, as long as there are no obvious contaminants, you can not wash it, because the meat is also cooked at high temperature during cooking, this process will sterilize, so from the perspective of food safety, there is nothing to do without washing problem. What should I pay attention to when handling ingredients purchased during the epidemic? 1. Washing with pots In order to prevent splashing pollution, it is recommended to wash the meat you buy at home first. Since cleaning and processing require direct contact with raw meat, you can consider wearing gloves. If you do not have gloves, then pay attention to washing your hands with soap and running water for at least 20 seconds after handling raw meat, poultry, aquatic products, etc. according to the recommendations of the Health and Health Commission. However, some people may worry that the basin where the meat is washed will be contaminated, so when not in use, the basin can be placed in a place where the sun can shine, such as a balcony, or sterilized with 75% alcohol after use. In addition, raw meat can also be treated in this way, first boil a pot of water, put raw meat in boiling water for 10 minutes, so that the virus and bacteria on the surface of the meat can be basically killed, and then processed. 2. Pay attention to the separation of raw and cooked foods. Whether it is a pot for cleaning food ingredients, a chopping board for handling food ingredients, or a container for holding food ingredients, they should be separated to avoid mixing. Also, items that have been in direct contact with raw food ingredients should be disinfected regularly. To prevent virus contamination. 3. Pay attention to hand hygiene. After direct contact with raw meat, do not rub your nose and eyes, or touch other objects before washing your hands. Because many people in life sometimes do the above behavior inadvertently due to their habits, it is also possible for the virus to spread. In short, the process of washing meat also needs attention to details. From this, we can see a process of hospital prevention and control. At the same time, the recommendations given by the state during the epidemic are very practical and effective for preventing the spread of new coronavirus. As long as we are implemented according to national guidelines, the spread of the new coronavirus will be cut to the maximum.

After the staged victory in the previous stage, with the orderly and gradual resumption of production throughout the country, many merchants, shopping malls and supermarkets have also begun to operate, and scenic spots have also been lifted. Even on weekends and holidays, many people start “revenge” travel and “revenge” consumption, which makes many people walking on the street once mistakenly thinking of returning to normal life. However, there have been several local counterattacks after the New Coronavirus epidemic. In particular, although this wave of outbreaks broke out in the new market in Beijing, although the current peak has passed, prevention and control are still in progress. Especially in the world, there are more than 10 million diagnoses of the new crown in the world. Against the background of the rebound of the epidemic in many countries, people are worried about the outbreak of the new crown virus. Some people are worried that the new coronavirus will come back when the weather gets cooler in October, will it? Will the new coronavirus make a comeback in October? Even so far, we still do not fully understand the new coronavirus, it has repeatedly made us feel its complexity and cunning. In an interview on June 23, Academician Zhong Nanshan expected that the new coronavirus will not disappear when it meets “this winter and next spring”. We cannot yet have an accurate estimate of whether it will come back, but the epidemic prevention and control cannot be relaxed, because it has the risk of coming back at any time. (1) The epidemic situation abroad is very hot and the global epidemic situation has been diagnosed with 9 million. There are 2.38 million confirmed cases in the United States alone. The fierce situation of foreign epidemics has brought great pressure to our country to prevent overseas imports. Just looking at the data from all over the world, the foreign epidemic situation in October may not be able to be controlled, let alone come out. (2) Concealed virus transmission From recent small-scale outbreaks, we can see that the new coronavirus is more difficult to deal with than we thought. The case of Tianjin where the source could not be found a few days ago, after the expert’s scouring and stripping, found that he was a chef in the same hotel. Although the chef’s nucleic acid test was negative, the serum antibody was positive. This further proves that the virus can be hidden deeper, people who may be infected have no symptoms, and even the source can not be found after the nucleic acid is transmitted to others, so don’t think that it is safe to have no cases locally. The protective measures should still be do. (3) The vaccine will be available at the end of the year at the end of the year. Fortunately, researchers from all over the world are working hard to develop a new crown vaccine. Our country is at the forefront of the world. Currently, five vaccines have entered clinical trials and are expected to be available at the end of the year. It is very difficult to make a vaccine successfully, but hope to get a new crown vaccine as soon as possible. In conclusion, no matter whether the virus comes in or not, we can not relax our vigilance. Epidemic prevention is a normal thing. Only by minimizing the risk of the rebound of the epidemic can we not give the new corona virus an opportunity to attack us again. Therefore, it is necessary to do safety protection and personal hygiene. In this epidemic, wearing masks is well known. After all, this is the most direct and effective way to prevent virus intrusion. In addition to wearing a mask, remind everyone to still pay attention to hand washing and disinfection, while remembering a sentence, distance produces beauty, and try to keep a distance of about one meter from others in public.

According to the latest news, the number of new crown epidemics that broke out at the beginning of this year has exceeded 10 million worldwide! The leap from 9 million to 10 million took only 6 days! Through such a set of data, everyone can know that the current epidemic situation is actually not optimistic, and it is still very serious. Some friends worry that if the epidemic in foreign countries is not controlled, will the epidemic in China break out again in the cold winter? Regarding this question, I believe that different people will have different answers. Let’s take a concrete analysis from the actual situation in the world and at home. The epidemic situation abroad is still in the development stage, and it is very difficult to control it comprehensively. Today’s latest data has not yet come out. The newly diagnosed in the United States was 40,949 cases yesterday, while the newly diagnosed in Brazil in South America was 46,860 cases, and the new cases in India It also surpassed 30,000 cases. These figures are showing us that the epidemic is far from over, and it is still in a full-scale outbreak in some areas. Take the United States as an example. During the development of the epidemic, there was a period when the epidemic in the United States increased by about 20,000 to 30,000 per day. It has continued. As the various states in the United States have implemented different prevention and control policies, people are required to stay social. Due to distance, wearing masks and other measures, the epidemic in the United States once showed signs of improvement. In a few days, the number of newly diagnosed people has fallen below 20,000. However, in recent large-scale demonstrations in the United States, states have resumed work and resumed business. The measures of business establishments, coupled with the arrival of the graduation season, the number of graduation parties in the United States has greatly increased, the gathering of people in the presidential election, etc., due to the continued increase in the concentration of personnel and mobility, the epidemic in the United States has further rebounded. The recent The number of more than 40,000 confirmed diagnoses has allowed the newly confirmed diagnosis in the United States to reach a historical peak. According to the analysis of the blood test statistics of the US Centers for Disease Control and Prevention (CDC), the actual number of infections in the United States is much higher than the official statistics. According to Robert Redfield, director of the Centers for Disease Control and Prevention, the actual number of infected people in the United States may be 10 times the number officially confirmed. According to this prediction, the official statistics of the number of infected people in the United States is 2.39 million, and the actual number of infected people should be Far more than this number. But at the same time, he also pointed out that the infection rate of the American population is about 5-8%, and 90% of Americans are still at risk of infection. Therefore, the US CDC still further emphasizes that people should maintain a social distance of more than 2 meters. Wear masks in public, and maintain a healthy habit of washing hands frequently, feel unwell, and try to stay at home as much as possible. As the United States with the world’s largest strength, the epidemic control is so bad, which is unexpected, while other countries that are experiencing outbreaks, such as Brazil, India and other countries, how will the epidemic control situation be done, and will It is difficult to predict how long the outbreak will continue, but one thing is clear: if the outbreak is still in continuous development from a global perspective, even a clear trough does not appear, there will be a further rebound. By this winter, the epidemic situation abroad may not consider the possibility of another outbreak, but the question of how to continue to strengthen prevention and control. According to the estimate of the US IHME model, by October 1 this year, the number of deaths due to the new corona virus in the United States will exceed 200,000, and if all people wear masks, this number can be reduced to 146,000. Therefore, how the epidemic will develop depends entirely on the importance of the governments of various countries to the epidemic and the intensity of the implementation of prevention and control measures. Will the domestic epidemic rebound in winter? It must be said that the domestic epidemic situation is still very good. Although there has been a new epidemic outbreak in Beijing recently, from the perspective of response intensity, speed of investigation, scope of investigation, speed of epidemiological investigation, speed of implementation of disease control measures, etc. After about 15 days, the epidemic in Beijing has been under initial control, and there are still new confirmed cases in time, which are all within the controllable range, and although sporadic cases are sporadic in other areas, But it can also be controlled in time. However, in the current epidemic prevention and control process, the spread of the new corona virus shows a strong concealment, and some experts pointed out that in many cases, the new corona virus is not disappeared, but hidden, under certain suitable environmental conditions , The new coronavirus will form an infection again, causing an outbreak, and in the cold winter season, we
As of this year’s Dragon Boat Festival, the United States has accumulatively diagnosed nearly 2.5 million cases of new coronary pneumonia and accumulated more than 120,000 deaths. What is the irony of the world’s most technologically advanced countries with the highest medical conditions and standards, but they are vulnerable to the New Corona virus? Even more ironically, US President Trump did not care about this death toll, but was proud of it. He also boasted in public that if the government he led took effective prevention and control measures, this death toll Probably 2 million. It is undeniable that the majority of people in the United States who die from new pneumonia are poor people living in the lower classes of society. So, the more people die, the fewer the poor will be? The more dead people, the more poor people will be created. Every country will have upper and lower class stratification. This is the essence of society that cannot be changed. The lower class generally represents the poor, and we cannot simply think that as long as the poor of the lower class die more, there will be fewer poor people, and the country will become richer. On the contrary, because the population becomes smaller, it also means that consumption and labor are reduced, which will seriously affect the social economy and make more people poor. According to the statistics of the US government, the unemployment rate in the United States reached 14.7% in April this year, the highest level since the Great Depression, which was generated in the context of the new crown epidemic, so this is the best evidence. If the epidemic is left uncontrolled again, the greater the number of deaths, the higher the unemployment rate in the United States and the more poor people it will create. Isn’t the US president really anxious? In fact, the US President is also aware of this, but due to reasons such as the US system and culture, Trump cannot take the same prevention and control measures as our country, and many American citizens cannot take the initiative to cooperate with forced isolation. If you use too much force, it is likely to promote social unrest, not to mention that Trump has a more important task this year, which is to run for re-election, and the popular support rate is what he really wants. Therefore, he would brag about his anti-epidemic performance in the country, and at the same time “dump the pot” in our country, continue to brainwash the people in the country, arouse the hatred of the American people against our country, and then establish a tough image of our own. Can easily get the support of the people. But such lies are doomed to cover up the truth. With the development of the new crown epidemic, the number of diagnoses and deaths continue to rise, and the American people will gradually recognize the truth and gradually lose patience with Trump. Therefore, Trump is actually very anxious. If he is not in control of the epidemic, it will greatly affect his approval rate. In short, for this new crown epidemic, many people think that on the other hand, it looks like a mirror, reflecting the ugly side of the capitalist country, and with the superiority of our system, I believe that it will surpass in the near future. United States. At the same time, from the perspective of the community of human destiny, we hope that all ethnic groups in the world, regardless of skin color, rich or poor, can work together to fight the new crown virus.

At the outbreak of the new crown epidemic at the beginning of this year, many people thought that the new crown virus would naturally disappear after the summer, because the SARS virus was also the same in that year, and the new crown virus was not heat-resistant and could be inactivated at 56°C for 30 minutes. But the reality is that the northern hemisphere of the earth has already entered the summer, but the new crown epidemic in many countries is still very serious, such as India in the tropical region of the South Asian subcontinent. The recent epidemic in Beijing, my country, has also made people nervous after a little relaxation. Will the epidemic come again in the second half of the year? On June 20, Zhang Wenhong, director of the Department of Infection of Huashan Hospital Affiliated to Shanghai Fudan University, pointed out on Weibo: Beijing gathers the city’s superior medical forces to carry out centralized treatment in Ditan Hospital, which should ensure the efficiency of treatment. As for the direction of the outbreak, according to the current prevention and control efforts, the outbreak can be completely controlled within 2 weeks after the peak of the outbreak. While Beijing’s epidemic situation is being accelerated and controlled, high-epidemic countries are under pressure from the economy and gradually adopting a policy of comprehensive opening up, which will bring great uncertainty to the global epidemic situation. Regardless of the arrival of the vaccine, the global epidemic will spread at least until the end of the year and the first half of next year. Will we return to the state of shutdown and production again? In fact, this kind of thinking is too worrying, as our internet celebrity professor Zhang Wenhong said: “For a long time, local Chinese cases will continue to be in a state of “near zero cases”, rather than no cases.” This time Beijing The current scale of the outbreak is still in a state of dissemination, which has not reached the point where a major outbreak has occurred. Our government has already had very mature experience in responding to the epidemic. As Beijing quickly raises the emergency response to public health emergencies to the second level and adopts strict and detailed investigations, we believe that Beijing’s epidemic will soon get Containment and gradual quelling, so it is unlikely that we will go back to work stoppage. The virus can survive under normal high temperature. Will the epidemic come again in the second half of the year? Yes, as the weather turns colder in the second half of the year, the epidemic may indeed return. Although the death rate of New Coronavirus is not as high as that of SARS, its transmission ability is strong. The most important thing is that there are no vaccines and special medicines to deal with, so it is likely that the new coronavirus will coexist with us for a long time in the future like flu, adenovirus and other viruses. If we relax our vigilance, it may be A local epidemic will erupt. Even so, we must also have firm confidence, because our country is the most successful country in the fight against epidemics. The previous anti-epidemic experience also tells us that the joint prevention and control measures we have taken are effective, so we need to This joint defense and joint control has become a normalized work, and Professor Zhang Wenhong also said: “For sporadic cases, as long as we maintain the current joint defense and joint control system, the spread index can quickly come down.” In addition, our vaccine research and development is also in the forefront of the world, I believe that our new crown vaccine will be available for market soon, so in the second half of the year we need to do not relax our vigilance, but also do not need to overreact. Regardless of the epidemic prevention strategy adopted abroad, China will continue to maintain a cautious attitude and maintain the hard-won stability. On the basis of the continued consolidation of epidemic prevention work and the continuous strengthening of the public health system, while steadily advancing the resumption of production, it will be quite a long time in the future. The “new normal” over a period of time. Finally, for everyone, wearing a mask, maintaining social distance, not gathering, and washing hands frequently is the best measure to prevent the new coronavirus. We must not forget at any time.

This epidemic in Beijing has touched the hearts of countless people! Since the local epidemic situation in the new market in Beijing recently, after checking the market environment samples, the imported salmon chopping board was tested positive and became a hot topic for everyone to discuss, which also led to the salmon being removed from Beijing’s major supermarkets overnight. At present, Beijing is still continuing to carry out all kinds of epidemic prevention and control measures, and the source of the virus is still under tension. Many people are worried that the outbreak in Beijing is related to eating seafood. Maybe it was spread from salmon to people. In addition, Wuhan was also the outbreak in the seafood market at the beginning, and some recently tested positive samples of salmon oral throat swabs and other in vivo specimens According to the news, the view of fish-to-people seems not unreasonable. At the same time, many scholars object to this view, insisting that fish cannot be infected with the new coronavirus. In the end, is it fish-to-human or human-to-human? Was the Beijing epidemic a succession of fish? The cause of the outbreak in Beijing is still under investigation, and it is unclear where the problem occurred. However, after a comprehensive official report and analysis by experts, the author believes that the probability of Beijing’s outbreak is not directly related to salmon, and our current prevention and control focus should still be on controlling people to people. The main reasons are as follows: (1) There is insufficient evidence of virus infection in the fish itself. It is understood that although the virus was detected on the board of the imported salmon this time, no new coronary pneumonia was detected for the salmon before entering the contaminated site through the test. virus. The salmon chopping board is not only touched by salmon, it may be the person who uses the chopping board, or other items may also be taken to the chopping board, and this needs further investigation. From June 13, the environmental sampling nucleic acid test results of seafood and aquatic markets across the country are negative, which further proves the “innocence” of salmon. Recently, some news about the positive test of in vivo specimens such as salmon oral throat swabs has not been officially confirmed, and the authenticity needs to be verified. At the same time, the possibility of seawater pollution is not ruled out. (2) Before our research on viruses was different between fish and human species, experts still favored the possibility that bats are the natural host of the new coronavirus. Among them, there is a certain relationship between bats and humans, which are mammals. We know that the new coronavirus is mainly transmitted through the respiratory tract, and the main symptoms are also in the lungs of the respiratory tract, and the fish have no lungs, especially the salmon is marine fish. If it is infected with the new crown, it will be difficult to spread in the vast ocean. (3) The presence of asymptomatic infections in the virus is more difficult than other viruses to deal with because of the presence of asymptomatic infections. This is the root cause of the virus’s elusive and unpredictable nature. Generally, due to asymptomatic or mild symptoms, even if it is transmitted, it will have little effect, but when an asymptomatic infected person goes to a densely populated place such as a new place and does not wear a mask, it will trigger a large outbreak. Therefore, this epidemic is likely to be related to asymptomatic infections, and the main reason may still be to return to the “human-to-human” transmission chain. Gao Fu’s explanation: People are not likely to pass on people. On June 16, Gao Fu, director of the Chinese Center for Disease Control and Prevention, once said, “(New Crown Virus) will lurking in some dark shadows, more polluted, and a bad environment. This is No one thought of it. After lurking, it was suddenly exposed to many people at a certain time. Beijing is probably not the patient who appeared in early June and the end of May this time. It is likely to be pushed one month in advance. There are already many Symptoms of infection or mild patients only produce so many viruses in the environment.” If Academician Gao’s guess is correct, this reminds us that imported seafood or meat products are contaminated and foreign viruses are more likely to enter the country! How do you understand the European viruses hot in the media, the viruses in Europe, and the old viruses in Europe? If it comes from the cold chain, then it is easy to explain that this shipment was not just packaged, because shipping still takes a long time, so the time the virus was packaged was a long time ago. The match is the interpretation of the ancient European virus. If it comes from a person, this is not easy to explain. A very early person who has been infected with the new crown virus of European direction has been lurking in Beijing for so long, and then went to the new place to infect other people? This feeling does not conform to the laws of science. In conclusion, at present, the source of the virus is not so easy to get answers. For cold chain transportation from all countries in the affected area, including air transportation and
The recent epidemic in Beijing has continued to develop, and many people have raised the question: Isn’t the new coronavirus spread from person to person? Why did some experts point out that the item might be spread to people? How is this good? The friend who asked this question himself had a certain misunderstanding about the spread of the new coronavirus. First of all, let’s take a look at the situation of Beijing’s epidemic. The Beijing epidemic, including related cases spread to other provinces, is mostly related to the wholesale market of the new place. Most of the confirmed cases at the beginning are the new place. Practitioners in the market or those who have been to the place of new occurrence, the subsequent confirmed cases are also closely contacted with the cases confirmed in the new place. Therefore, from the source of the possible spread of the virus this time, the source of the epidemic has been basically confirmed, and the experts on the specific transmission route have also given two possibilities, one is interpersonal transmission, the other is through Item spread. Needless to say, interpersonal transmission, close-to-person droplet transmission and close contact transmission are likely to cause viral infection, and this method of transmission of objects to people, many friends can not understand, but in fact Everyone may have forgotten that at the beginning of the New Crown Outbreak, many friends had worried that the meat dishes they bought would be infected with viruses and cause infections. Isn’t this a possibility for the items to spread to people? It has been pointed out for a long time in the relevant guidelines that the new coronavirus can be spread through droplet transmission and contact transmission. Droplet transmission is interpersonal transmission, and the scope of contact transmission is wider. In addition to the contact between people, if a person is in contact with a virus-contaminated item, it is useful to be infected with the virus before effective hand washing. If you touch your mouth and nose, it is possible to form an infection with the new coronavirus. Therefore, the possibility of the new coronavirus spreading through the items still exists. Judging from the situation of the Beijing epidemic, although the source of the epidemic has not yet been finalized, the possibility of spreading it from person to person is still very high, especially for imported fresh products transported by the cold chain, because the virus can last for a long time at low temperatures Survival, this item contaminates the virus, and the chance of the virus eventually causing human infection is still very high. A recent cluster outbreak in Germany also gave an example. According to a German TV report on the 17th, a meat processing factory in western Germany confirmed 657 cases of new crown infections. This factory is currently closed. This gathering Sexual outbreaks have resulted in at least 7,000 people being quarantined. The same meat processing plant has experienced an epidemic situation, which has also occurred in other overseas countries such as the United States. Therefore, the new coronavirus is not only spread from person to person. Harmony can also be spread, and special attention should be paid to the possibility of refrigerated and frozen fresh products spreading to people. #德肉联厂终终产品产品输输华# But for such a possibility, you don’t have to over-interpret and worry too much, as long as it can be handled correctly and carefully protected, the new coronavirus is made of fish, meat, etc. The possibility of passing fresh products to people is completely avoidable. Recently, the National Health and Safety Commission issued the “Guidelines for the Prevention and Control of the Normalization of New Coronary Pneumonia Epidemic Situations in Key Locations of Key Units in Key Areas in Summer in Low-risk Areas”. In this guide, the protection requirements of food consumers, food practitioners and other groups are added There are two main points: In particular, food consumers should wash their hands with soap and running water for at least 20 seconds after handling raw meat, poultry, aquatic products, etc. Do not rinse raw meat products directly under the faucet to prevent splash contamination. If we can take personal protection when purchasing fresh products, do not touch the nose and mouth with fresh hands, wash hands promptly after purchasing, and try not to wash meat, aquatic products and other products Rinse directly with a faucet (avoid splashing) and wash it by soaking. At the same time, after handling fresh food, remember to regulate hand washing again. Fresh food should not be eaten raw. Try to cook it after cooking. If you can strictly do the above Note: Fresh food can also be purchased and eaten. There is no need to worry too much about the problem of fresh coronavirus infection.
When everyone thought that the new crown epidemic in China had achieved a staged victory and could breathe a sigh of relief, the development of the Beijing epidemic was unpredictable. Especially in less than a week, there have been more than 100 local confirmed cases. Many people are panicked and puzzled. How did the Beijing epidemic progress so fast? It has progressed faster than the previous case in Wuhan. So why? Why is the Beijing epidemic developing so fast? Facing the severe epidemic situation, Beijing has adjusted the emergency response level of public health emergencies from three to two. Even so, the Beijing epidemic still affects the hearts of people across the country. There should be several reasons for the rapid development of the epidemic: (1) The virus is highly infectious. We know that the new coronavirus is generally susceptible to people and has the characteristics of asymptomatic infections. So it is easy to hide from the crowd and not be found, it is more difficult to deal with than SARS. And there are many ways of transmission, not only through the respiratory tract, but also through contact and aerosol. This Beijing epidemic cannot rule out the possibility of imported fresh seafood pollution causing New Crown to enter Beijing, which shows the complexity and cunningness of New Crown virus. (2)Beijing has a large population, and the new development area has a huge flow of people. As the capital of our country, Beijing has a population of more than 20 million. With frequent personnel exchanges, it is more difficult to prevent and control than other places. Moreover, the initial location of the new epidemic market is the market for agricultural products supplying more than 80% in Beijing, and it is also the largest professional agricultural products wholesale market in Asia. Every day, there are at least tens of thousands of people. Due to the infectivity of the new coronavirus, the spread of so many people is also expected. (3) Faster and stronger detection methods The number of people diagnosed with the Beijing epidemic situation in recent days has been followed by 20 or 30 people, which is also related to the government’s strong screening efforts At present, Beijing is racing against time to carry out testing, traceability and epidemiological investigations. Our current detection methods are also much better than Wuhan’s original. According to official reports, Beijing can sample about 400,000 people a day, and nucleic acid detection kits are also in sufficient supply, so we will see more real diagnosis data. (4) Psychological negligence of the epidemic The Beijing epidemic also taught us a good lesson. I have to admit that after the new crown epidemic was under control in Wuhan, people in many parts of the country no longer had the previous vigilance against the new crown virus, thinking that the virus was already far away from us. Many people were there, many people did not wear masks in crowded places. The venue also canceled the temperature measurement for people entering. Psychological negligence of the virus is the main reason for this repeated epidemic. Conclusion Although the epidemic in Beijing has progressed so fast, with our previous experience of fighting the epidemic, I believe that the situation will be quickly controlled. But this experience also tells us not to relax our premature prematurely. The virus is not as easily defeated as we think. While preventing and controlling the input of foreign personnel, we must strengthen the quarantine of imported agricultural products.

The recent situation of the new crown epidemic in Beijing has made people all over the country very worried. Everyone knows that the place where the epidemic broke out again is the agricultural product wholesale market in the new place of Beijing. According to the Beijing Municipal Center for Disease Control and Prevention, since the rebound of the Beijing epidemic, the hundreds of newly diagnosed new crown cases have all been related to the place of new occurrence. And just after the Xinfadi farmers market, a new crest virus was detected in another vegetable market in Beijing! According to media reports, the sampling of the environment inside and outside the Guangtao Tiantao Honglian vegetable market in Xicheng District, Beijing, and the results of individual nucleic acid tests were positive. Recall that at the beginning of the new outbreak of new pneumonia in Wuhan at the beginning of the year-South China Seafood Market, why did the outbreaks occur in markets with a particularly concentrated population? Is it coincidence or inevitable? New crown epidemic outbreak in the market? It is not coincidental that a virus must break out, and there are three conditions: the source of infection, the route of transmission, and the target of transmission. For places that meet these three conditions at the same time, I think the most likely one is in the hospital and the other is in the market. Needless to say, the hospital, but because of the strict control, procedures and supervision of hospital sense prevention, it will not easily make the virus outbreak. This is not the case at the bazaar. First of all, the source of the commodities in the bazaar is complex, some are local and some are foreign, some are domestic and some are foreign. Once some products are contaminated by the new corona virus, or become the intermediate host of the new corona virus, then it will become a source of infection, just like the pangolin in the southern China seafood market, it is highly suspected as the intermediate host of the new corona virus, and this time The salmon in the new market is also likely to be contaminated by the virus. In addition, there is a large flow of people in the market, so it is inevitable that there will be people infected with new coronary pneumonia, which is also one of the sources of infection. The new coronavirus is mainly spread through droplets and contact, and the market environment can also meet this route of transmission. The market is densely populated and poorly ventilated indoors, which will form a relatively closed environment. Once there is a source of infection, its droplets can easily form aerosols in the air. Even if everyone wears a mask, it will inevitably inhale the new crown virus. Aerosols cause infections. Finally, whether it is the buyer or the seller in the market, it is inevitable that they will come in contact with different items. If you do not pay attention to hand hygiene, it will also cause virus infection. The last is the target of transmission. The population of New Coronavirus is generally susceptible, and everyone in the market will become the target of New Crown Virus. Therefore, it is no coincidence that every outbreak is in a market where the population is particularly concentrated, but that the market is the place where the three elements of virus transmission are the easiest to meet. This wave of epidemic in Beijing has given us a warning. This rebound of epidemic in Beijing has sounded the alarm for the prevention and control of the epidemic in the whole country, and has brought very important revelation. In the context of the global new crown epidemic, we must not only prevent the spread of human beings, but also cannot ignore the prevention and control of objects; we are most concerned about the input of foreign infected people, and may ignore the agricultural and sideline products from overseas to The hidden virus in the country enters the chain of transmission, which may give the virus a chance to spread. In conclusion, the epidemic in Beijing tells us again that even though the epidemic in most of our areas has basically subsided, the threat of the new coronavirus still exists, and there may be a small-scale outbreak in the future for a long time, so you must not relax Be vigilant, especially when crowds gather. On the contrary, everyone should continue to maintain social distance when going out.

The recent epidemic in Beijing has been repeated, and people throughout the country are paying close attention! At present, the emergency response level of public health emergencies in Beijing has been adjusted from three levels to two levels. All grades of primary and secondary schools in Beijing have ceased to attend classes at schools, and colleges and universities have stopped returning to school. Since the outbreak of the outbreak in the new market, the situation of Beijing’s epidemic prevention and control is grim, and the government is stepping up screening. The current situation in Beijing is similar to that in Wuhan. Many people have raised a question: Beijing will be closed like Wuhan. ? Beijing and Wuhan are different. There are three differences. According to the current situation, Beijing is unlikely to be closed. Although it seems that Beijing has reported more cases than Wuhan initially reported, the situation is also very complicated, but today Times are different. The following aspects were different from Wuhan at that time: (1) The source of the virus was different. Although it was an outbreak in the seafood market, the original virus source in Wuhan has been a mystery, but the virus in Beijing has been analyzed by experts. The European virus lineage, which may be traced back to March and April, is highly likely to be imported abroad. At that time in Wuhan, because everyone knew little about the new coronavirus, its transmission route, whether it was passed from person to person, survival time, etc. were gradually understood over time, but now we do not fully understand the new coronavirus, but it is also considered With certain experience, I can find the source of viral genes in the first time. Of course, further source analysis is waiting for the experts to announce. (2) The response efficiency of the government and the citizens is not the same When Wuhan’s outbreak just started, the government and the citizens did not attract enough attention, and it was the Spring Festival of the annual peak of traffic, so they ordered the closure of the city. As soon as the epidemic was discovered, Beijing immediately closed the market and surrounding communities and concentrated relevant personnel to perform nucleic acid tests. Within a week, the government responded in a timely manner. The public is also familiar with the new coronavirus. After the previous experience of quarantine at home, they will also cooperate with the government’s various measures, which is very helpful to control the epidemic. (3) Preparation is not the same as supplies. Beijing’s medical staff, medical facilities, prevention and control materials, and knowledge of virus prevention and control knowledge are much better than Wuhan. After the national anti-epidemic campaign in the past few months, both medical staff and the general public have a scientific understanding of the epidemic and will not panic as before. Masks, protective clothing and other materials have been fully stocked by the state’s strong support and rework in all walks of life, and there will be no shortage or robbery. Conclusion According to the current situation, Beijing is unlikely to be closed, but this epidemic has also made us aware of the complexity and uncertainty of the new coronavirus. Ordinary people can pay attention to protection in their daily lives, so they can protect themselves well and prevent the virus from spreading. Scattering is the biggest contribution to the country. It is recommended to do the following in daily life: (1) Try not to eat raw food, even if it is delicious salmon, temporarily hold back not to eat raw! Including cold vegetables and fruit salad. (2) Wash your hands promptly after returning to the vegetable market or after contact with fresh food. Wash your hands before eating, and wash your hands immediately after returning home. (3) Knife, chopping board for raw meat, bowls and dishes with raw meat, wash them with detergent as soon as possible, and sterilize the cabinet after disinfection, prepare a set of knives, chopping board, dishes, bowls, especially for handling raw meat. (4) You must wear a mask when you go to a place with a lot of people. Although the weather is hot now, compared with the terrible new crown virus infection, you have to put it on! (5) Seek medical treatment in time for symptoms such as fever or cough, especially when the symptoms get worse, you must go to see a doctor in time, and you should not delay treatment on your own. Especially for compatriots in areas with high risk of outbreaks, it is particularly important to visit emergency or hot clinics in a timely manner. If necessary, eliminate the new coronavirus infection through nucleic acid detection, so you can rest assured.

At the beginning of the outbreak of the new crown epidemic in my country early in the year, a friend once asked why there have been fewer people suffering from colds and illnesses around me recently? Recently, with the control of the epidemic, all parts of the country have basically resumed work and resumed production and returned to school. People with colds and coughs have gradually increased. In addition, there has been a certain rebound in the epidemic in Beijing in recent days. Many friends have begun to worry. Will cold, cough, fever and other symptoms be related to the new crown epidemic? Regarding this issue, I suggest that everyone should still look at it scientifically and rationally. Why are there more people who have a cold or cough recently? For this question, we can compare why there were fewer colds during the epidemic. In the epidemic outbreak stage, everyone is very careful. Whether it is wearing a mask, washing hands, ventilating, and gathering as little as possible, most people are very careful and careful. Such epidemic prevention and control measures , Not only can effectively reduce the risk of spreading the new coronavirus, but also reduce the spread of other infectious viruses, such as cold viruses, such as influenza viruses, such as some other pathogens transmitted through droplets and contact, etc., by wearing Protective measures such as masks and hand washing can indeed reduce the risk of infection as much as possible, so one of the phenomena we have seen is that when everyone is well protected, colds occur around them, and the number of sick people is greatly reduced, even if it is It turns out that some people who have poor resistance and often catch colds rarely have a cold. Why are there more people who have a cold or cough recently? In fact, this phenomenon is not at all surprising. Now that the domestic epidemic situation has been initially controlled, most areas have been reduced to low-risk areas, and they have been fully resumed work and school. Two reasons have led to the occurrence of colds. Increased, first of all, the mobility of people has become greater, whether it is resumed work or resumed school, or the re-opening of various commercial complexes, tourist attractions, have greatly increased the mobility of personnel, and the probability of personnel gathering has also increased on a large scale. In this case, the probability of catching a cold virus will also greatly increase, and of course the number of people with a cold will also increase. Another reason for the increased cold and cough is the gradual relaxation of the protection awareness of the crowd. Let’s take a look at the surrounding area. How many people have not worn masks for a long time, how many people have given up the habit of washing hands frequently, and how many people have resumed their lives at the same time, they have started to take out food all day, not paying attention to food hygiene The reduction of such protective measures and the relaxation of prevention and control consciousness will of course lead to the spread of the virus. In addition to the recent hot weather, friends who have the conditions have turned on the air conditioners in their homes. Low, the chance of catching a cold or cold will also increase greatly. Therefore, it is now found that the number of people who have a cold and cough around them has increased. In fact, it is an external manifestation of our gradual relaxation of epidemic prevention and control awareness. If we can persist in the prevention and control during the epidemic, in addition to normal life and work, Trying to reduce the number of closed places where people are crowded is believed to be helpful in preventing the occurrence of infectious diseases such as colds. Recently, many people have cold and cough symptoms. Is it related to the new crown? On this issue, we still have to look at and think dialectically. New coronavirus infections will have such symptoms as fever, cough, chest tightness, shortness of breath, etc. There may also be some atypical symptoms. Therefore, it is impossible to judge fever and cough by symptoms. New crown virus infection, cough, fever 1. Whether the symptoms such as runny nose are related to the infection of the new crown, we first need to look at the epidemic prevention and control situation and risk level of the location. If the new crown epidemic in the location has been cleared long ago, and no other outbreaks have occurred, In the absence of the typical symptoms of New Coronary Pneumonia, linking cold symptoms to New Crown Virus infection is a bit too worrying. You may take more rest at home, drink more water, pay attention to a healthy and reasonable diet, and take cold medicines to relieve symptoms related to symptoms. To see if you can heal without worrying too much. However, if you are in the epidemic outbreak itself, or have had close contact with the relevant diagnosed person in the epidemic outbreak, or even if you are not in the epidemic place, you have fever, cough, chest tightness, shortness of breath and other typical symptoms, while taking cold medicine And other related drugs, and the symptoms can not be effectively relieved, you may also do a nucleic acid test of a new coronavirus
Looking at the national epidemic data today, Beijing has newly added 27 confirmed patients. In recent days, there have been more than 100 new cases in the local area, 4 new cases in neighboring Hebei Province, and 1 new case in Sichuan Province. These The cases are closely related to the wholesale market of the new origin of the epidemic in Beijing. Although the epidemic occurred in the large wholesale market with personnel and material mobility, the prevention and control of the epidemic have certain difficulties. Fortunately, the related cases of this outbreak can find the source, which also makes us full of hope and confidence that the outbreak can be effectively controlled. According to recent news from various sources, the new coronavirus was found on the sampling board of the newly cut imported salmon, and the main virus strains of the epidemic were also found during the gene sequencing of the virus in the epidemic. Genetic testing showed that the new coronavirus mainly came from Europe, so many friends speculated that the outbreak was mainly caused by contaminated virus during the cold chain transportation of overseas fresh products. So thinking about the epidemic outbreak in Wuhan area is also the seafood market, some friends asked, will it be imported because of the fresh food abroad, during the cold chain transportation process? For this problem, we analyze it from two aspects. First of all, did the source of Beijing’s epidemic really come from overseas cold chain imports? So far it has not been fully confirmed. But it is undeniable that this possibility is still very large. Whether the virus was found on the cutting board of the salmon, or the gene sequencing showed that the virus originated in Europe, these evidences initially point to the occurrence of the outbreak and belong to the possibility of overseas imports. bigger. But in the end how it was imported from abroad, and what kind of product was brought into the virus, it is worth further detailed investigation and research, and further sampling data and scientific analysis are needed to further prove. In the follow-up work, it is very important to clarify the specific source of the virus. At the same time, we should also do the inspection and quarantine of imported items, especially cold chain transport items, to minimize the possibility of importing virus infection through “items” . It should be noted that the gene sequencing of the virus shows that it originated in Europe, but it does not mean that the virus must have been imported from Europe. After all, many investigations and studies have shown that the outbreaks in the United States and Russia are also related to European coronaviruses. Homology, therefore, we should do more comprehensively and meticulously to prevent foreign imports. Secondly, whether the epidemic situation in the Wuhan seafood market is the spread of seafood or other ingredients transported by cold chains abroad, it is still really difficult to verify. After all, the current epidemic situation in Wuhan has been basically controlled, and sampling and testing again from the seafood market may not necessarily be able to The new coronavirus was detected. After the outbreak of Beijing, the Environmental Health and Food Safety Institute of the Wuhan Center for Disease Control and Prevention conducted the third environmental sampling test of supermarkets and farmers’ markets. As of June 15, more than 3,000 samples were collected The nucleic acid test results of New Coronavirus are negative. Therefore, it is difficult to prove whether the virus from the South China Seafood Market came from overseas cold chain imports. If you want to investigate this possibility, one way you can think of is to wonder whether the virus samples of related cases related to the seafood market were preserved in the early stage of the Wuhan epidemic, and whether the virus could be determined by gene sequencing of such samples. Is the genotype of the virus similar to and related to viruses outside the country? If it can be confirmed that the virus type of the relevant cases in the Wuhan seafood market is related to the virus type in the overseas epidemic, then the possibility that the epidemic in the Wuhan seafood market originated from overseas cold chain transport imports is relatively large. Although it has been a lot of uncertainty for a long time, the source of the investigation and research is always a matter of active verification and scientific judgment. I hope that with the continuous deepening of the investigation of the epidemic, we can really find Beijing The exact source of the outbreak has even found the true source of the outbreak in our country.
The recent rebound of the Beijing epidemic has caused turmoil in the hearts of the people throughout the country. Since the initial media reports that dozens of employees in the new market in Beijing have positive swallowing swabs, it has led to multiple discussions. Some people are worried that Beijing’s improper handling of the epidemic may As a result of the second outbreak, authoritative experts also voiced this: Beijing’s joint defense and joint control system is very complete and believes that epidemic control is a high probability event. It seems that we are more relieved, but the news reports that the pharyngeal swab is positive. It is worth discussing. How is the pharyngeal swab checked? Does pharyngeal swab positive mean diagnosis of new coronary pneumonia? How is the throat swab checked? Is a positive throat swab a diagnosis? In fact, pharyngeal swabs are just a sampling method for inspection. The person being inspected opens his mouth and sounds “ah”. The inspector presses his tongue with a tongue depressor, and then uses a long cotton swab from the palate on both sides of the person being inspected. Wipe the bow, pharynx, and tonsils to obtain secretions for testing. So pharyngeal swabs are actually cotton swabs with pharyngeal secretions. The determination of the new coronavirus requires a pharyngeal swab for nucleic acid detection of the virus. If the nucleic acid test is positive, it means that the person being tested is infected with the new coronavirus. Because the examination of pharyngeal swabs is a simple and convenient sampling method for viruses transmitted by the respiratory tract, most pharyngeal swabs are currently used to determine whether there is a new coronavirus in the body. So for those 45 people, the new coronavirus has been detected, is it a diagnosis? This is related to our country’s diagnostic criteria for confirmed patients. According to the latest “New Coronavirus Pneumonia Diagnosis and Treatment Program (Seventh Edition)”, the diagnosis of new coronary pneumonia requires fever, dyspnea and other respiratory symptoms, and the lung images suggest that there are new coronavirus infection characteristics, or blood routine Examinations suggest that more than two of the viral infections should be combined with epidemiological history. On this basis, a positive nucleic acid test can confirm the diagnosis. For example, since the outbreak of the new Beijing epidemic, according to the staff of the Beijing Center for Disease Control, some of these 45 people have no symptoms, so they can only be regarded as asymptomatic infected persons, but not as confirmed patients with new coronary pneumonia, they need to accept 14 days Isolation observation, if symptoms appear, follow the diagnosed case treatment, if there are no symptoms re-examine the pharyngeal swab, there are two tests that are more than 24h apart and the test is negative to release the isolation. How to treat multiple cases of pharyngeal swab positive in Beijing Xinfadi market? Beijing Xinfadi Farmers’ Market is not a large market, with a total area of more than 1,500 acres, a total construction area of 210,000 square meters, an average daily flow of more than 80,000 people, and more than 5,500 fixed booths. It can be said that this is an area with a very high population density and a very large mobility of people. Some people even call it the logistics headquarters of Beijing. There are many cases of pharyngeal swabs positive, and subsequent reports confirmed dozens of new crown infections, which have a certain impact on the market supply, although it does not hinder the overall situation. In addition, due to the high population density in the new development market and the flow of 100,000 people per day, the challenge for epidemic prevention and control can be described as huge. First, the workload of tracking close contacts is extremely huge, and the potential The risk of the spread of the epidemic is also quite large. It can be said that the work pressure in all aspects of tracking, tracing, prevention and control is very huge. Conclusion Positive pharyngeal swabs are a medical term and a means for us to detect new coronavirus infections. The new epidemic situation can be detected in time thanks to this inspection. At the same time, Beijing’s joint defense and joint control system has also played a huge role. Although the current situation of Beijing’s epidemic prevention and control is grim and there are certain uncertainties in the subsequent development, due to Beijing’s rapid and precise measures in prevention and control measures, I believe that the epidemic will be controlled as soon as possible.

The New Crown Epidemic, which has been steadily declining, has been affected by the new epidemic in Beijing in recent days, which has once again touched the hearts of many friends. Today’s data has not been released, but in recent days, the number of newly confirmed local cases in Beijing has exceeded 50, and these newly confirmed cases are all related to the new wholesale market. Such a situation It reminds many friends of the beginning of the outbreak in Wuhan, and the seafood market in South China was also the hardest hit by the epidemic. Why is the fresh market always easy to become a place for virus transmission? What should be the difference between this outbreak and the outbreak in Wuhan? Today we will analyze it carefully. The epidemic occurred in the fresh market, whether it is the wholesale market in Beijing’s Xinfa District or the seafood market in South China, of course, there are certain commonalities. Such markets are often large in scale, many kinds of fresh food, population density, and mobility of people are also relatively In such a case, if a virus is contaminated on fresh products that are refrigerated, the low temperature environment is more suitable for the survival of the virus, so the probability of direct or indirect contact transmission will be greater. Once the virus forms and spreads, due to the influence of factors such as high personnel mobility and strong virus spreading ability, the uncertainty of this new crown virus epidemic that is related to the fresh market will be greater, and the difficulty of prevention and control is often also Very large. However, if we analyze carefully, the epidemic situation in the new-origin market is still very different from the epidemic situation in the South China seafood market in Wuhan. First of all, the South China seafood market in Wuhan was in the early stage of the outbreak. Because of the new virus, the outbreak situation here, due to various reasons, began to attract attention after a long period of time. Compared with the South China Seafood Market, after the outbreak in Beijing, the relevant disease control departments were able to quickly deduce the new location of the wholesale market as a related place, and in a very short time, quickly carried out environmental sampling and surrounding The investigation of the crowd, therefore, although the fresh market at the same time, from the perspective of the speed of epidemic control, due to the accumulated experience in epidemic prevention and control, the new epidemic occurred in the new place, from the speed of control to the scope of control, should be fast too much. Second, from the investigation of the source of the epidemic situation, the situation in the South China Seafood Market is also different from that in Beijing’s new market. Where did the virus in the South China seafood market come from? There is no clear conclusion in the end, but from the current news, whether the new crown virus is found in the imported salmon cutting chopping board in the new market, or the recently announced gene sequencing results, this new crown The type of virus mainly comes from Europe. If we use this information to make a preliminary judgment, the source of the virus is likely to be imported from abroad. One possibility that cannot be excluded is that the freshness of the new crown virus is contaminated outside the country. The product brought the new coronavirus to the market, which caused related human infection problems. I believe that the current epidemic in Beijing is only the initial stage. In the process of comprehensive investigation, the source of the virus and the spread of the virus will be more clearly confirmed, but at the same time, we should also believe that due to the rapid Response mechanism, rapid disease control measures, the possibility of further large-scale outbreak of this epidemic is not very big, but if it is confirmed that the virus is caused by imported fresh commodities, how to further strengthen the epidemic Anti-input, how to do a good job of foreign defense imports from overseas immigrants, to foreign defense imports of foreign entry goods, is one of the topics worthy of our deep consideration and consideration.
News from Beijing is very unsteady this weekend! At the weekend, the most interesting news is the news of Beijing’s diagnosis of multiple cases of new coronavirus infections, because Beijing, as the capital of the first good, once the development of the epidemic area has unbearable consequences! What is very strange is that the origin of the diagnosis of the patient this time is the seafood market, but the blame is not on the bat. This time is salmon, imported salmon. Due to the special nature of the capital, the masses automatically filled up a lot of thrills. Plot. Why did the virus reappear in the seafood market and Beijing? Is salmon really the heart of the empire? Here we are still rational to discuss one or two. Why did New Coronavirus appear again in Beijing? As an international metropolis with a very high population density, it is actually not an accident that Beijing again broke out. Similar to the previous local outbreak in Heilongjiang and Liaoning, Beijing is also located in the north. At present, we cannot determine the specific cause of the emergence of new coronavirus in Beijing, and further investigation is required to know. But it should not be that the salmon is infected with the virus and then spread to humans, although salmon may indeed carry a variety of parasites. This is because the new crown can basically infect humans and other mammals. There is no evidence that fish can be infected with the new crown virus. According to the previous research of the new coronavirus by scientists, we know that the new coronavirus is mainly transmitted through the respiratory tract or contact. As a fish without lungs and only gills, it is difficult to infect the new coronavirus through air breathing, and the imported salmon is a marine fish. In the vast sea, the bats in the deep forest and old forest that scientists initially suspected are very far away. Even if the sea corona virus is contaminated with new coronavirus, it can be easily diluted. Scientists have previously studied the infection method of the new coronavirus and found that the new coronavirus mainly binds to the ACE2 receptor on the cell membrane, and studies the ACE structure of different animals to find that the virus is not easy to bind to the ACE2 receptor of fish. And the chopping board test was positive, but there were no reports of salmon test positive. Therefore, the possibility of salmon infection with new coronavirus is very low, but just in case, it is better not to eat raw food, it is better to cook it cooked. The new crown epidemic in Beijing may be related to pollution in the transportation and processing of seafood. Before this, there had been outbreaks of infections in food processing companies abroad. The transportation of seafood from abroad to my country may be contaminated by viruses, and then shipped to China after being frozen and stored. Conclusion: The epidemic has not passed yet, everyone still needs to be alert to the outbreak of the new coronavirus in Beijing, and also warned us that the new coronavirus is more difficult to deal with than we thought. It may swept over again at any time, and only normalized epidemic prevention and control In order to contain it again. At the same time, we need to pay attention to that pollution is not equal to infection, infection is not equal to disease, and carrying is not equal to the host. Therefore, we should attach great importance to the monitoring of cold chain transportation. After all, low temperature is conducive to the survival of the virus. In the post-epidemic era, we need to pay more attention to food safety and practice. Personnel detection.

This weekend, the news of newly diagnosed cases in Beijing and the market of new places has been screened. For this, I agree with the opinion of Professor Zeng Guang, the chief expert of the Chinese Center for Disease Control: This new case in Beijing will not be an emergency for Beijing. Response to the level of prevention and control has an impact, and at present, individual cases will not affect the risk level of Beijing. According to this view, the control of people returning to Beijing from other places will be strengthened, but there will be no essential changes, and those who return should be able to return, but at the same time, both returnees and local residents need to continue to implement various anti-epidemic measures according to the previous prevention and control strategies. . Does the addition of multiple confirmed cases in Beijing mean that the epidemic can recur? Three new diagnoses were confirmed, reminding us that we should be alert to the possibility of local rebound in the epidemic, but the possibility of another pandemic is not high. The specific analysis is as follows: (1) The virus is highly contagious. The new coronavirus is more contagious than SARS, and there is a general population Susceptible, there are characteristics such as asymptomatic transmission. Therefore, the new coronavirus pneumonia is more hidden than SARS and more difficult to deal with. (2) The epidemic situation may rebound at any time. In April, Heilongjiang once broke out that the epidemic situation may break out twice, and the news of “1 pass 80+” appeared. After the efforts of the government and citizens, all the infected people found contact and isolation only on June 9. The example of Heilongjiang and the news of new cases in Beijing remind us that the virus has been watching around us, and a little slack will swept through. (3) The epidemic is still raging abroad. More than 7 million people have been diagnosed abroad. Various countries are taking measures, and some countries are not well under control of the epidemic situation, which has caused great pressure on my country to import from abroad. After all, with the development of globalization today, it is easy to go from one country to another, at most one ticket. The virus will follow people to any place in the world. (4) Vaccines have not yet been marketed. At present, there are already vaccines in our country that have begun clinical trials, but the immunogenicity, protection effect and safety of the vaccines still need a lot of time to study. Whether they can be successfully marketed and used Whether it can meet expectations is currently uncertain. The best expectation is that it will be developed by the end of this year. However, the vaccine will be successfully marketed, and we must consider whether the production capacity can meet people’s needs, whether the protection time will be short, and so on. Conclusion The domestic epidemic situation can only be said to have achieved a staged victory at present, and it is still a long way from complete control. Through the most primitive method, 1.3 billion people across the country were isolated at home, and the mobilization and containment of the people made the virus nowhere to spread. Only this stage of victory was achieved. Looking at the development of the epidemic situation abroad, we know how rare our current state is. Barry is only half of 90. The results we have achieved so far are hard-won. The fight against the virus may be a long-term protracted war. You can’t think that you can overcome the virus and relax yourself. For your health, you should pay attention to washing your hands, ventilating, and avoiding crowds. At this point, you must wear a spare mask when you go out.
