What is hemorrhoids? Can hemorrhoids be contagious?

&nbsp.&nbsp.&nbsp.&nbsp.&nbsp. Hemorrhoids is a disease in the anal area, that is, a red bump grows inside or outside the anus. As the hemorrhoids will gradually grow, the symptoms will also get worse. Common symptoms include blood in the stool, prolapsed hemorrhoids, pain, mucus or pus, and itching. &nbsp.&nbsp.&nbsp.&nbsp. Hemorrhoids may appear at any age, and the older the age, the higher the incidence. At present, the medical profession believes that the following causes of hemorrhoids are related: 1. Standing or sitting for a long time. 2. Genetic factors. 3. Drinking alcohol and eating spicy food stimulate the anus. 4. Constipation and diarrhea. 5. There is a wound in the anal area and the virus is infected. There are many reasons for hemorrhoids, so you should pay attention to your lifestyle. &nbsp.&nbsp.&nbsp.&nbsp.Can hemorrhoids be contagious? &nbsp.&nbsp.&nbsp.&nbsp. When it comes to infectious diseases, everyone is more afraid. If you are sick, if it is an infectious disease, you will worry about spreading it to your family, and your family will worry about spreading it to yourself. Patients suffering from infectious diseases will have a low self-esteem, which also affects his treatment. &nbsp.&nbsp.&nbsp.&nbsp. The so-called infectious disease must meet three conditions: source of infection, route of transmission, and target of transmission. The cause of hemorrhoids is not viruses or bacteria. Sometimes the bacteria that cause hemorrhoids are just incentives. In this way, there is no pathogen in hemorrhoids, and it is impossible to be an infectious disease. &nbsp.&nbsp.&nbsp.&nbsp. As for why many people think hemorrhoids are contagious, it is probably due to family inheritance. Hemorrhoids itself will not be passed on to the next generation, but if the father or mother’s anal vein wall is weak, it is easy to suffer from hemorrhoids, and this characteristic will be passed on to the children, and most of the family members suffer from hemorrhoids, which is mistaken for It is contagious. &nbsp.&nbsp.&nbsp.&nbsp.In addition, white-collar workers, drivers, clerks and other long-time sitting jobs have a high probability of suffering from hemorrhoids. There may be many employees in the same company who suffer from hemorrhoids, which are mistaken for infection. . &nbsp.&nbsp.&nbsp.&nbsp. Generally speaking, hemorrhoids are not contagious. To prevent hemorrhoids, it is necessary to exercise regularly, eat healthy and abstinent, and develop good bowel habits.

Now that you know the suffering of syphilis, you still want to cure it?

In film and television dramas, we can often see women in the ancient brothel standing at the door to welcome customers: uncle, come and play? ! In fact, this phenomenon was impossible before the Ming Dynasty. Because the literati and scholars of the ancients all thought that singing and singing in Fenghuaxueyue place was quite fashionable and cool. The women in the brothel are also very high-eyed. Unless there is a real “mine” at home, there is no poetry. It is very difficult to make a smile on their faces only by “Yuanfang” (money). Regarding these, we only need to look at Tang poems, Song poetry, Yuan opera, and Ming novels to find out. Some people might say that those cultural people are not afraid of getting “ill” when visiting brothels? Not to mention, they are really not afraid! People before the 16th century had never seen the severe disease of xìng at all, because people at that time had at most only seen Hualiu disease (gonorrhea). With the introduction of syphilis from abroad to China through Guangdong, people really realized the harm of sexually transmitted diseases. It was also from that time that there began to be people who did not sell their lives. Historical data show that in the 1940s and 1950s, there were approximately 10 million patients with syphilis in China. Moreover, the incidence of congenital syphilis is as high as 28% in children under 15 years of age. Our country has taken a series of measures such as banning the hospital. By 1964, syphilis was basically eliminated, until after the reform and opening up, syphilis was brought in from abroad. Data show that in 2018, a total of 494,867 cases of syphilis were reported nationwide (an increase of 3.99% from 2017). In Shanghai, syphilis has even become the most common infectious disease. Because syphilis can not only cause pustules and ulcers on the skin and mucous membranes of the whole body, but even destroy the patient’s appearance, it can cause irreversible damage to multiple organs in the late stage, and even cause death. At the same time, syphilis will increase the risk of HIV, and it can also be transmitted from mother to child to the fetus, leading to stillbirth, miscarriage or neonatal death. Therefore, everyone should pay attention to relevant protection, avoid unclean behavior and unhygienic tattoos, and it is strictly forbidden to share syringes. Although syphilis now ranks third in the category A and B legal infectious diseases, as long as penicillin is used, based on the principle of early, adequate, and standardized treatment, the first and second syphilis can be completely cured. However, because syphilis often has a certain degree of concealment and incubation period in the early stage, some people have a fluke mentality; or some people refuse to seek medical treatment for fear of being discovered by others for their own disorder… all of the above, the result In the end, it can only harm others and self, and regret it too!

Summer diarrhea may be this disease? Do 8 points, the intestines are healthier

The three people took a diarrhea and cleared the area. After so long, they could finally go out and enjoy it. So they asked some friends to indulge in the night market. So, a few of us are really self-willed, from one end of the night market to the other, eat whatever you want, and when you go home, the trench is already flat, which is quite satisfying. But diarrhea started in the morning. As soon as I called, a total of 3 people had symptoms of diarrhea, and I took the medicine quickly. Since we ate while walking last night, no one of us can be sure what caused it. Who knows whether it’s skewers or oysters… In summer, we must pay attention to intestinal infectious diseases. Summer is coming, and intestinal diseases are frequent, especially if there are The collective illness of the collective diet may basically be an intestinal infectious disease. Why should be careful of intestinal infectious diseases in summer? 1. The temperature in summer is high, the bacteria multiplies faster, and the food is easy to spoil. 2. The amount of hot drinking water increases. Drinking a lot of water will reduce the concentration of stomach acid and reduce the acidity of the stomach. Pathogens will take advantage of the deficiency and make them sick. 3. There are many raw foods. Melons, pears and peaches are easily infected with bacteria in the process of growth, picking, transportation and sales. Eating unwashed fruits and vegetables can cause illness. As for street night markets and small vendors at night, cooking does not pay attention to hygiene, and the disinfection of tableware is not strict. Practitioners have not undergone health checks, and even patients with intestinal infections are engaged in direct food imports, which is more likely to spread diseases. 4. In summer, flies multiply in large numbers, fly around, pollute food, and people are susceptible to intestinal infectious diseases after eating. How to prevent intestinal infectious diseases? Sickness is the most appropriate for intestinal diseases. The preventive measures are very simple, that is, wash hands frequently, eat cooked food, drink boiled water, and do a good job in environmental hygiene. 1. Washing hands is the most important personal preventive measure. Washing hands before and after meals can wash about 90% of the microorganisms on the hands, greatly reducing the chance of pollution. 2. Do not drink raw water, because boiling water can kill pathogenic microorganisms. 3. Eat cooked food, eat less cold dishes, wash it when eating, and wash and sterilize raw fruits and vegetables; do not eat spoiled food, sick and dead poultry, livestock, stale food, do not buy; try to eat as little as possible Foods that cause pathogens, such as screws, shells, crabs, and other aquatic products, should be cooked and steamed before consumption. Eating raw, half-life, wine, vinegar, or salted food is not advisable. 4. Try not to eat leftover food. If the leftover food should not be stored for too long, it should be heated before consumption, subject to heat penetration. 5. The tableware should be strictly sterilized, and the cooking utensils used for raw and cooked food should be separated; it is best not to eat in small outdoor eating stalls on the roadside. 6. Do a good job of indoor and outdoor sanitation, remove garbage, dredge sewage ditches, and eliminate infectious diseases such as flies, mosquitoes, mice, cockroaches. 7. At the same time, individuals should pay attention to work-rest combination and ensure adequate sleep, improve self-immunity, and help prevent infectious diseases. 8. If you have symptoms such as vomiting and diarrhea,   must not be careless. Seek medical treatment immediately for early diagnosis and early treatment. But if you have to say, I just want to lose weight through diarrhea, I will not stop, but be careful, severe diarrhea may cause dehydration, and even more serious infections and complications. And if it is an intestinal infectious bacterial infection, bacterial dysentery, typhoid fever, paratyphoid fever, etc.; amoebic dysentery caused by amoeba histolytica; there are many types of viruses, including poliovirus and coxsackie virus , Ekovirus, new enterovirus, etc., can cause polio, hand, foot and mouth disease, viral encephalitis, herpes angina, and other diseases. It is easy to cause the group to get sick, and it will be big.

Scientific vaccination to improve disease resistance

Children with antibodies from the mother within 6 months of birth are generally less susceptible to infectious diseases. This kind of antibody protection from the mother is called passive immunity. After 6 months, the antibody from the mother in the child is gradually reduced, and the antibody produced by the child is very small, so the resistance is the worst at this time, and there is a high possibility of infection. So, how can you improve your baby’s immunity? Vaccination allows your baby to produce its own antibodies, which is a method to deal with various infectious diseases, called active immunization. The importance of vaccination: Without vaccination, once infected with the disease will seriously endanger the health of the child, and even cause life-long disabilities and death. Therefore, vaccination should be carried out on schedule. After birth, the baby should be vaccinated according to the planned immunization sequence. Parents must pay attention to take the child to be vaccinated on time. Are there any adverse reactions to vaccination? After the child is vaccinated, the body is stimulated by foreign antigens, which will produce an immune response, which is inevitable and beneficial. If the fever is below 38℃ after inoculation, generally no treatment is needed, and it will return to normal after 1-2 days. Some babies have redness or induration at the injection site, which is also a common adverse reaction, and generally does not require special treatment. It will subside after a few days. What should children pay attention to when taking vaccination? 1&nbsp.&nbsp. should be carried out when the child is in good health. Suspension of vaccination while being sick; 2&nbsp.&nbsp. The body temperature should be measured before vaccination. If there is fever, the vaccination should be postponed, and the injection should be suspended before the full recovery of health. 3&nbsp.&nbsp. After vaccination, do not take a bath that day, nor let your child get too tired. 4&nbsp.&nbsp. Allergic constitution should be explained to the doctor. 5&nbsp.&nbsp. Individual children may have a high fever after vaccination, please ask the doctor to see and give symptomatic treatment. Which children cannot be vaccinated temporarily? If your child has a fever, suffers from acute infectious diseases, asthma, rubella, eczema, or other diseases, such as heart disease, nephritis, and hepatitis, do not vaccinate temporarily. Don’t take polio sugar pills when your child has diarrhea. You can’t eat it until two weeks after getting sick. Children with seizures whose seizures have not been controlled, and children with a history of drug allergies, need to be evaluated by a doctor to decide whether to vaccinate.

To win the plague, you must know this knowledge!

&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp. 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.&nbsp. What is plague? &nbsp.·&nbsp.&nbsp.&nbsp.&nbsp.&nbsp. 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. &nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp. 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.&nbsp. The prevalence of plague&nbsp.·&nbsp.&nbsp.&nbsp.&nbsp. 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. &nbsp.&nbsp.&nbsp.&nbsp. 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. &nbsp.&nbsp.&nbsp.&nbsp. 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&nbsp.·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? &nbsp.·1.&nbsp. Source of infection&nbsp. (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.

Will hemorrhoids be contagious?

 Is hemorrhoids contagious? In the middle and late stages of internal hemorrhoids, there will be symptoms of internal hemorrhoids prolapse. What harm does internal hemorrhoids prolapse? Prolapse of internal hemorrhoids is caused by the lack of elasticity of the supporting tissue under the hemorrhoids due to injury. Generally, you can repay in the early stage of withdrawal, and you need to help repay by hand in a long time. It should be particularly emphasized that when prolapse of internal hemorrhoids, no matter what the circumstances, must be promptly received. Obstruction of local blood circulation will occur, and varicose veins or even thrombosis will occur in the protruding part, and the volume will increase. At this time, the anus is prone to contraction and contraction due to pain, which will make the prolapsed internal hemorrhoids unable to be recovered, resulting in incarnation or even necrosis, infection, suppuration, ulceration, etc. If the patient is in severe pain, unable to sit or walk, cannot defecate normally, or even cause bowel obstruction, the consequences will be very serious.  Is hemorrhoids contagious?   First look at the medical characteristics of infectious diseases. Infectious diseases are diseases caused by viruses and bacteria and spread by air, food, and other various contacts.  It can be seen that there are three necessary conditions for infectious diseases: source of infection, route of transmission, and target of transmission. The cause of infectious diseases is viruses or bacteria.   The occurrence of hemorrhoids is not caused by bacterial or viral infections. Hemorrhoids are caused by venous reflux obstruction, stasis, and varicose of the mucous membrane and muscular layer of the rectum and anus caused by various reasons. They are not directly related to viral and bacterial infections.   Sometimes the mucous membrane of the hemorrhoids is eroded, and even infected and purulent becomes an anal abscess, but it is not related to the cause of the hemorrhoids themselves, it is only a factor that induces hemorrhoids.   In addition, hemorrhoids themselves will not produce pathogens. Therefore, hemorrhoids themselves are not contagious. If a patient with hemorrhoids suffers from intestinal infectious diseases, then it is only possible to be infected with intestinal infectious diseases, and hemorrhoids can be induced over time, and hemorrhoidosis cannot be contracted immediately.   In short, hemorrhoids have a lot of harm to the human body, should arouse the attention of the majority of clinical workers, and treat every patient with hemorrhoids seriously. Hemorrhoids patients do not need to be too nervous, as long as they can be treated early and treated properly, they can avoid the occurrence of the above serious complications.

Why should we close management, wear masks and not get together during the epidemic?

Since the outbreak of the New Crown epidemic, everyone has heard the most and insisted on doing “closed management, wearing masks, not getting together and not gathering” every day, and after these measures, the outbreak can be effectively controlled. So why do you insist on these measures? In fact, these measures are inseparable from the three links of infectious diseases and the three principles of infectious disease prevention and control. First look at the three links of infectious diseases. They are the source of infection, the route of transmission and the susceptible population. Let’s analyze some of the new crown epidemic situation: first, the source of infection is the new crown virus, but animals and people infected with the new crown virus will become the source of infection; the transmission route is mainly through respiratory droplet transmission and close contact transmission; if the susceptible crowd, the crowd It is generally susceptible, but the elderly, people with underlying diseases, and obese people are more susceptible to infection and are prone to develop severe illness. The three principles for the prevention and control of infectious diseases are the corresponding measures for these three links, which are managing the source of infection, cutting off the transmission route and protecting the susceptible people. After tracing the location of the epidemic to the seafood market, the rapid closure of the South China seafood market in Wuhan and the new development and Beijing-Shenzhen markets was to manage the source of infection. When a certain number of aggregated cases occur, in order to prevent the spread of the epidemic, communities with aggregated cases will be closed, and even the city of Wuhan with a population of 10 million people will be closed for management, which is also to manage the source of infection. Why should you wear a mask? This should start from cutting off the transmission route, because the main transmission method of the new crown epidemic is through the respiratory tract droplets, so wearing a mask can effectively cut off this method; at the same time, there are some transmission methods including contact transmission, so we should also encourage everyone Wash your hands frequently, don’t touch your eyes, touch your nose, cook meals, etc. Because the new coronavirus is generally susceptible to the population, it is necessary to teach everyone about the spread of disease and make everyone aware of the disease. Everyone works together to protect themselves and control the epidemic. Therefore, we call on everyone to “not get together” “Do not gather and reduce gatherings” is to protect every susceptible person. Although the infectious disease is powerful, but understand the three links of its spread, and through scientific prevention and control, I believe that the new crown epidemic will be controlled. At the same time, in the normalization of epidemic prevention and control, everyone can also develop many good habits, such as maintaining social distance, using public chopsticks, etc., which is conducive to everyone’s health.

Why plague and cholera, which were once popular in the world, are defined as Class A infectious diseases and what are Class A infectious diseases

According to the “Law of the People’s Republic of China on the Prevention and Control of Infectious Diseases”, there are 39 types of infectious diseases, including Category A, Category B, and Category C. Type A infectious diseases refer to severe infectious diseases that are highly contagious, have a high case fatality rate, and are prone to cause pandemics. Including plague and cholera. Once a Class A infectious disease is discovered, it must be reported through the infectious disease epidemic situation monitoring information system within 2 hours in urban areas and within 6 hours in rural areas. Mention the plague, everyone will think of the famous black death in the Middle Ages. In the middle of the 14th century, a plague called “Black Death” raged wildly on the European continent at that time, killing nearly 50 million people. This figure is equivalent to 1/3 of the total population of Europe at that time. The plague raged three times around the world. It was not until 1894 that the deadly pathogen of the Black Death, plague bacillus, was discovered. The fleas, after sucking the blood of rodents such as mice infected with plague, bite people again and cause infection. Why can plague become a Class A infectious disease? 1. High mortality plague is divided into three types: bubonic plague, pneumonic plague and septic plague. The bubonic plague is relatively weak, and can only cause 50-60% of patients to die without medical intervention; the pneumonic plague has raised a grade, with a mortality rate of more than 95%, which becomes very scary; Septicemic plague, the patient died of hemorrhage after the onset of the disease. Not only is the mortality rate close to 100%, but the body of the dead body is black after death. 2. Strong infectivity, it is difficult to control the plague can be spread through contact, droplets, the most important way of transmission is flea bites. There is a possibility of plague in areas with rodent infestation. 3. The epidemic time is long. The three pandemic of the plague lasted nearly two and a half years, the second was more than three hundred years. The most recent one did not completely end until 1959, and it also took nearly a hundred years. With the improvement of sanitary conditions, plague is no longer possible, but there are still sporadic occurrences in China. The most recent cases are 2 cases in Inner Mongolia in 2019. Why is cholera a Class A infectious disease? Cholera is a severe intestinal infectious disease caused by Vibrio cholerae. The most common symptom is diarrhea. The stool is watery like swill. The patient will be fatal due to severe dehydration. If not treated, the case fatality rate is between 50% and 60%. After active treatment, the case fatality rate can be controlled below 1%. Vibrio cholerae can survive for a long time in seawater, river water and well water. If the water containing Vibrio cholerae is directly consumed without treatment, Vibrio cholerae can enter the human body by mouth. Vibrio cholerae can be transmitted by water, food, living contact and vector insects (flies). There have been seven cholera epidemics in history. Among them, the one in 1991, the seventh, was the most serious and affected many countries, with nearly 600,000 patients. Every time a cholera pandemic begins, it starts in the coastal areas and gradually deepens inland. In terms of time, there is no typical cycle, it can be all year round, usually in summer. The latest cholera epidemic was in Yemen in 2016, involving nearly 200,000 people, half of whom were children. Cholera spreads quickly, spreads widely, and is harmful. The most obvious feature is the sudden outbreak (even multiple regions simultaneously), and its ability to cause a global pandemic across regions and years. When a cholera outbreak occurs in large areas, there is a huge need for fluid replenishment, medication and isolation requirements for each patient, including clean drinking water that the public must have, etc. Compared with other infectious diseases, this huge demand for explosive growth of medical supplies, clean water sources, and other relief materials such as medical personnel and treatment sites in a short period of time will directly reach the limit of the country’s emergency capabilities. Therefore, China has classified cholera as a Class A infectious disease. The typical characteristics of Class A infectious diseases are strong contagiousness, rapid spread, and high mortality, which pose a serious threat to national public health. This new outbreak of new coronary pneumonia has the characteristics of strong infectivity and rapid spread. Although the mortality rate is not as good as the previous plague and cholera, it is extremely harmful to the public. Therefore, it is controlled as a category B infectious disease.

Will the dead body caused by the new crown infection be thrown into the sea, and will it infect people? Read the truth behind the article

At present, there are about 180,000 deaths due to new coronary pneumonia in the world. The top three countries are the United States, Spain and Italy in order, and behind the data are all living lives. While feeling sad, people can’t help but wonder, how do these countries deal with dead bodies that have died from infection with the New Coronary Pneumonia virus? Will any country throw it into the sea, and if it is thrown into the sea, will it be transmitted to people through the marine life chain? Will the birds eating rotten corpses be infected? To know the answers to these questions, we must first know how each country handles the body of the new crown? How to deal with the dead bodies of patients with new crowns? Large-scale infectious diseases have appeared many times in human history. Various countries and relevant departments have formulated relevant laws or regulations on this. Generally, people who die due to infectious diseases will be cremated. Article 46 of the Law of the People ’s Republic of China on the Prevention and Control of Infectious Diseases of our country stipulates that: If a category of infectious disease dies, it shall be treated immediately with physical hygiene and be cremated nearby. If other communicable diseases die, if necessary, deal with physical health after cremation or deep burial, in accordance with relevant regulations. (Regardless of nationality, race, and religion, death in China must be cremated nearby). Since the outbreak of New Coronary Pneumonia, our country has classified New Coronavirus as a second-class infectious disease and treated it as a first-class infectious disease. Therefore, all patients who died of New Coronary Pneumonia were cremated. The new coronavirus dies within 30 minutes at a temperature of 65 degrees, so cremation is the most effective and safest way to kill the virus. In New York, USA, because there are too many deaths and more than the daily processing capacity of funeral homes, the government buried many new corpses after disinfection and burial on an uninhabited island called Hart Island. It is also relative to completely isolate the virus through burial. It is safer, but the premise is to carry out effective disinfection of the corpse, otherwise it is very easy to cause transmission during transportation. Countries such as Italy and Spain have generally adopted the method of cremation. Both of these methods can ensure safety. However, cremation costs are relatively expensive in some economically backward countries such as India and Africa. Many residents cannot afford cremation fees and will adopt the method of water burial. If some people do not undergo nucleic acid testing before death, they do not know whether it is carried by a virus If they are thrown into the sea or river after death, if this is the case, the body is not likely to be sterilized, and it is very likely to carry the virus. The virus can be transmitted through direct contact or feces. If the fish eat After corpses, humans ate uncooked fish again, which is likely to be transmitted to people through the food chain, but the probability is very small. As for whether flying birds eat rotten corpses carrying the new coronavirus, will they be infected? There is not a lot of scientific research to explain this, and we cannot make a blind judgment. To sum up, we cannot be overly nervous and self-defeating for the epidemic, but we cannot be overly optimistic, because our understanding of the new corona virus is still very limited, so we must be vigilant, be prepared for a protracted war, and put an end to any possible occurrence The problem, therefore, for safety reasons, it is recommended that all countries in the world strictly deal with the dead bodies of patients who died due to the new crown, adopt the method of cremation, which has the highest safety factor, and be responsible for the life of themselves and others.

What is scarlet fever and how to prevent it

Scarlet fever is an acute respiratory infectious disease caused by group A β-streptococci. Clinical manifestations are fever, angina, and diffuse rashes on the skin of the whole body, and some patients may have “myrica tongue” (red tongue, red and swollen tongue papillae). Complications of joint and kidney allergies may occur in some cases. The disease spreads through the respiratory tract. Occurrence season winter and early spring season. The age of onset is mainly in children aged 2 to 10 years. To this end, the nursery institutions should strengthen the morning inspection and find that the patients leave the hospital for treatment in a timely manner. Strengthen the disinfection of tableware and toys in collective units such as nursery institutions, and pay attention to indoor air circulation. Families should pay attention to opening windows regularly and drying clothes frequently. Be trained in good personal hygiene. What is scarlet fever? How to prevent scarlet fever? Winter and spring seasons, the temperature is changeable, is the season of respiratory tract infections. The immune function of children and adolescents is relatively low, and it is a key population for the prevention of respiratory infectious diseases. So, how to do prevention and nursing work? 1. Keep work, study and living environment ventilated and ventilated, classrooms should open windows after each class, other teaching and living rooms should be opened windows 2-3 times a day , More than 30 minutes each time. Especially in the bedroom, the doors and windows must be opened when leaving. 2. Try not to organize teachers and students to go to places where the crowd is concentrated. 3. Pay attention to personal hygiene. Wash your hands often with soap and running water, especially after sneezing, coughing, and cleaning your nose. Do not share tea sets and tableware. 4. Pay attention to increase and decrease clothing and balanced nutrition, strengthen outdoor exercise to ensure adequate rest and enhance physical fitness. 5. The school should strengthen the morning inspection work, find suspicious patients in time, and at the same time strengthen health education to teach teachers and students about disease prevention. 6. If students find fever, cough, fatigue, muscle soreness and other symptoms, they should immediately tell the teacher or parents and seek medical treatment in a timely manner. The teacher should seek medical attention in a timely manner if they find symptoms of appeal. 7. School sanitation rooms should be regularly disinfected according to regulations. 8. The school should report the morbidity in the school in time according to the regulations. If the school finds a suspected patient confirmed by the medical and health institution, it should be reminded online according to a famous doctor: Scarlet fever is an acute respiratory infectious disease. Generally, it is transmitted through the respiratory tract through coughing and sneezing.

There are so many foreign infections, what if we reach group immunity?

67% of people were accidentally found to be infected during blood donation. On April 2, according to the European Union News Agency, 67% of blood donors in a small town in Italy have antibodies. The town is located in the most severe area of ​​Lombardy in Italy. Of the 60 people who donated blood, 40 had a positive test for the new coronavirus, but they did not have any symptoms, did not know that they were infected, and had produced viral antibodies in their bodies. These people are completely unaware that they are carriers of the virus and have been active in the town. Some of them are still working. At present, these people have been quarantined at home. No one wants to have so many people infected, indicating that many people have been infected outside the detection, then these people who do not know that they have been infected are mobile sources of infection, and will definitely allow more people to be infected. With more than 67% of the entire population, will it really be able to achieve the group immunization promoted by the United Kingdom? Conditions for group immunization So-called group immunization. An infectious disease has many people in the population who have acquired immunity. This proportion is related to the spread of the disease. The spread of the disease is low, so the proportion of people who get immunized is lower. In general, infectious diseases have the concept of a basic number of infections, which is represented by R0. In epidemiology, it means that a person infected with a certain infectious disease will have no external intervention and no one has immunity. The average number of other people who spread the disease to others. In general, the condition for infectious diseases to spread among susceptible people is R0> 1. If R0 of the new coronavirus this time is about 3, that is, an average of 3 people per person. According to this ratio, it takes 66.7% of human infections to form group immunity. If the actual R0 of the virus is greater than 3, then more infection ratios are needed to achieve group immunity in the mathematical model. Measles must achieve group immunity. The proportion should reach 99%. According to this infection rate, it means that we have completely surrendered to the virus, and Germany, which has the lowest mortality rate of the new crown infection, is also about 2%, so it is really too expensive to make people immunized after infection. Take the 66 million people in the United Kingdom, for example, the group reached immunization, with more than 40 million infected people. The case fatality rate is 2%. There are 800,000 deaths. But now the data released by the United Kingdom is more than 10%. Now the British prime minister also lives Enter the ICU. Foreign control is not good in case of group immunization, what do we do now is not very ideal for foreign control, from the perspective of Italian towns, if this continues, if the infection rate in some foreign countries reaches the number of group immunization, then they have formed a natural protection . Our country cannot be closed forever. What should we do? Should we also let go? Use this method? In fact, to achieve group immunity, there can be a natural process or intervention with a vaccine. The latter is the most ideal, it can reduce disasters to a minimum, and even eliminate certain infectious diseases, such as smallpox. Although the United Kingdom claims to require group immunization, some countries also have poor control, but it is not a matter of two days to achieve group immunization. At the same time, various countries are actively controlling the spread of the epidemic. degree. During this time, what we need to do is to actively research effective vaccines. At present, the fastest vaccine success will take about 1 year. During this time, all countries in the world could not achieve group immunization at this rate of infection. So don’t worry about the fact that foreign countries are really immunized. Are we dangerous? Because we were able to achieve group immunization through vaccination.

0-6 years old | Unplanned vaccines (on)

Vaccines are an important weapon to protect your baby’s health. However, the “unplanned vaccines” that have emerged in recent years have left many parents at a loss, some say that they should be given to their babies, while others say not. Whether the unplanned vaccine will be vaccinated or not, please see the opinions given by experts. Essential difference between unplanned vaccines and planned vaccines The division of vaccines within and outside the plan is mainly based on the infectiousness, epidemic and degree of infectiousness of infectious diseases. The infectious diseases involved in the planned immunization are not only widespread in all parts of the country. Both healthy babies and babies with weak constitutions are susceptible to infection. They are also highly contagious and have a high mortality and disability rate. If it is not well controlled and spreads, it will cause great harm to human beings. Its “plan” carries the meaning of “compulsory” vaccination. Some of the infectious diseases targeted by unplanned vaccines are local or local epidemics (such as hemorrhagic fever, etc.); while some are widespread and highly infectious, they are self-limiting diseases that can heal themselves and return well ( (Such as rubella, chickenpox); some are not harmful to healthy babies, only threaten frail babies (such as flu, pneumonia, Haemophilus influenzae type B infection, etc.); some infectious diseases are closely related to man-made environmental conditions Related, such as rabies, although the mortality rate is extremely high, but as long as you do not keep dogs and cats, it is not easy to be infected. For these infectious diseases, the state does not need to provide preferential treatment. You can choose according to your own conditions and abilities without intervention. If a baby who does not complete the planned immunization may affect admission, admission or school, and a baby who does not receive the unplanned immunization will not be affected. Two unplanned vaccines for mumps vaccine are advocated: Once mumps develops, although most people turn out well, due to more mumps complications, they are prone to encephalitis, orchitis, ovarian inflammation, myocarditis, arthritis, etc. Mumps is also one of the causes of acquired deafness. Orchitis and ovarian inflammation can even affect the baby’s reproductive function in adulthood. Therefore, it is recommended that the baby be vaccinated in time for mumps. It is generally believed that babies who have not had mumps for more than 8 months of age should be vaccinated against mumps, especially babies who have lived collectively in nurseries and kindergartens, because collective life increases the chance of infection. Of course, babies who have had mumps do not have to choose anymore. Medical tips: Babies who have been injected with gamma globulin need to be vaccinated for mumps after a month interval; babies with severe infectious diseases, fever and a history of allergies should not be vaccinated against mumps. Because the measles and mumps vaccines are produced from chicken embryo cells and contain a small amount of neomycin, there are people who are allergic to eggs and neomycins to disable the leprosy vaccine and monovalent mumps vaccine. Chickenpox vaccine: Choose according to the specific situation, if the baby has poor resistance, it should be selected; it can be used for babies with good health. The reason for not using is that chickenpox is a benign self-limiting “infectious disease” and is not included in the scope of infectious disease management. Even if your baby has chickenpox, there are very few complications. However, varicella-zoster virus has a high degree of transmission through the respiratory tract, and after the primary infection of varicella, the virus can latent in the body for a long time, and then herpes zoster can occur when it encounters low resistance in adulthood. Therefore, it is recommended for babies participating in group activities. For babies who live scattered and do not participate in group nursery, do not need to be vaccinated. Medical tips: Those with a history of serious diseases, allergies, and immunodeficiency are prohibited. Babies in the general disease treatment period and fever period should use it slowly. * The content of this article comes from the Internet, only for sharing.
