It is possible that the baby’s flu fever can heal itself. The flu is caused by the flu virus infection. It often shows fever, fatigue, and mental health in the clinic. It can be accompanied by cough and sputum. In severe cases, it may be complicated by pneumonia and myocarditis It can also be life-threatening. Influenza is caused by influenza virus infection. For viral infectious diseases, if the baby’s own resistance is strong enough, it may not heal itself by taking antiviral drugs. But generally for influenza virus, if it is diagnosed clinically, it is still recommended to take oral anti-influenza virus drugs, such as oseltamivir, and some drugs that are more targeted for influenza virus. At the same time, children with flu need to be well cared for. If the baby has a fever when it gets flu, then the fever may cause the child to be mentally unwell. It is still necessary to choose a fever based on the body temperature. method. If the body temperature exceeds 38.5 ℃, it is recommended to give the baby oral antipyretic drugs. If the body temperature does not reach 38.5 ℃, it is mainly to take some physical cooling methods. Therefore, if the baby’s resistance is relatively strong, it is possible to cure the baby’s flu fever. But generally because there are still some antiviral treatments for influenza viruses, you can still give your baby some antiviral treatment under the guidance of a doctor, and do good care and symptomatic support treatment.
Original Shijiazhuang cerebral palsy rehabilitation center Shijiazhuang cerebral palsy rehabilitation center Today, Hebei Xianghe Health Management Co., Ltd. focuses on early childhood development intervention and rehabilitation education Of viral pneumonia. RSV has only one serotype, but there are two subtypes of A and B. my country is dominated by subtype A. The disease is more common in infants and young children, especially in children under 1 year old. It is generally believed that its pathogenesis is the direct invasion of the lungs by RSV, causing interstitial inflammation rather than allergic reactions, which is different from RSV bronchiolitis. Symptoms of fever and dyspnea are mild in clinically mild patients. Moderate and severe patients have more obvious dyspnea, wheezing, cyanosis of lips, fanning of the nose and tridentation signs, fever can be low, moderate and high fever, lung Most auscultations have medium and fine damp rales. Chest X-ray examination showed small patches and patchy shadows on both lungs, and some children had emphysema of varying degrees. The total number of peripheral blood leukocytes is mostly normal. (2) Adenovirus pneumonia (adenoviruspneumonia) Adenovirus pneumonia is caused by adenovirus (ADN) infection. There are 42 serotypes of ADV, and the most common types of children with pneumonia are type 3 and 7. ADV pneumonia was the most common viral pneumonia in children in my country. It accounted for the highest number of viral pneumonia before the 1970s. The highest mortality rate was 3%. The incidence rate is now replaced by RSV pneumonia. Type 7 ADV has 15 genotypes, and the clinical manifestations of pneumonia caused by 7b are typical and severe. The disease is more common in children from 6 months to 2 years old, and occurs frequently in winter and spring. The clinical features are rapid onset, long duration of high fever, severe symptoms of poisoning, late rales, and X-ray changes earlier than the appearance of lung signs, which are prone to myocarditis and multiple organ dysfunction. Symptoms are as follows: ① Fever: up to 39°C, with long-lasting heat or relaxation heat, which can last for 2-3 weeks ②Severe symptoms of poisoning: pale or gray, lack of energy, alternating sleepiness and irritability. ③ Respiratory tract Symptoms: The cough frequently shows paroxysmal wheezing, dyspnea and cyanosis of varying degrees of severity. ④ Digestive system symptoms. Diarrhea, vomiting, and gastrointestinal bleeding. ⑤ Sleepiness, coma, or convulsions can occur due to cerebral edema. Physical examination found: ① The rales in the lungs appear late, and it takes more than 3 to 7 days after high fever to show actual changes in the fusion of lung lesions. ② Liver and spleen enlargement, due to the strong reaction of the mononuclear-phagocyte system Cause. ③ Measles-like rash ④ Myocarditis such as accelerated heart rate, low heart sounds, heart failure and other symptoms of heart failure. There may also be signs of central nervous system such as meningeal irritation. X-ray characteristics: ①The changes of lung X-ray examination appear earlier than the lung duo, so emphasis is placed on early radiography. ②Shadow shadows of different sizes may merge into a large lesion or even a large leaf. ③The lesion absorbs slowly, It takes weeks or months. From the late 1980s to the present, the 7b type of ADV has been gradually replaced by the 7d type, and the pneumonia caused by the 7d type is relatively light and atypical. ADV pneumonia is prone to secondary bacterial infections. The person with secondary bacterial infection showed persistent high fever. The symptoms worsened or once improved and worsened. The sputum changed from white to yellow pus. The peripheral blood leukocytes increased significantly, and the nucleus moved left. Chest X-ray examination showed increased or Discover new lesions. Some ADV pneumonia can develop into bronchiolitis obliterans (BO), causing repeated wheezing. (3) Influenza pneumonia (influenzapneumonia) Since the 20th century, humans have experienced several worldwide pandemic influenza virus infection pandemics. Each influenza epidemic is related to influenza virus mutation. The population is generally susceptible to influenza venom, especially in children, infants and young children younger than 2 years of age: influenza virus pneumonia has a higher incidence during influenza epidemics. Influenza viruses belong to the Orthomyxoviridae family, single-stranded RNA viruses. According to the different characteristics of nuclear protein (NP) and membrane protein (MP) in virus particles, influenza viruses are classified into three types: A (A), B (B), and C (C). Influenza A virus is based on its surface antigens hemagglutinin (H) and neuramin
Children’s upper respiratory tract infections are mostly caused by viruses, often manifested as sore throat, stuffy nose, runny nose, cough, sputum, Western medicine antiviral drugs are generally effective. Lower respiratory tract infections include bronchitis, chronic bronchitis, pneumonia, and bronchiectasis. They are usually caused by infections such as viruses, bacteria, mycoplasma, chlamydia, and legionella. Their treatment must specify the pathogen causing the infection to select effective antibacterial and antiviral drug. Traditional Chinese medicine has a long history of treating acute respiratory tract infections. Whether it is upper respiratory tract infection or lower respiratory tract infection, the curative effect is relatively significant. The common pathogens of respiratory infections in children are Streptococcus pneumoniae, Haemophilus influenzae, Staphylococcus aureus, Chlamydia and Mycoplasma. Traditionally used penicillin or cephalosporin antibiotics, the efficacy is not good. Under the clinical background of antibiotic abuse and resistance limitation, Chinese medicine has given new ideas for the treatment of respiratory tract infections. Choosing some heat-clearing and detoxifying Chinese medicines to treat children’s respiratory tract infections often achieves good results. How to diagnose acute upper respiratory tract infection? According to the medical history, epidemic situation, nasopharyngeal inflammation symptoms and signs, combined with peripheral blood and chest X-ray examination can make a clinical diagnosis. Bacterial culture and virus isolation, or viral serology, immunofluorescence, enzyme-linked immunosorbent assay, hemagglutination inhibition test, etc., can confirm the cause of diagnosis. What are the clinical manifestations of acute upper respiratory tract infection? 1. Common cold is commonly known as “cold”, also known as acute rhinitis or upper respiratory tract catarrh, with nasopharyngeal catarrhal symptoms as the main manifestation. Most adults are caused by rhinovirus, followed by parainfluenza virus, respiratory syncytial virus, Echovirus, Coxsackie virus and so on. The onset is more acute, with dry throat, itching, or burning sensation at the beginning. At the same time or a few hours after the onset, there may be sneezing, stuffy nose, and runny nose. It will thicken after 2-3 days. May be accompanied by sore throat, sometimes hearing loss due to otitis, or tearing, dull taste, poor breathing, hoarseness, and a small amount of coughing. Generally no fever and systemic symptoms, or only low fever, discomfort, mild chills and headache. Examination showed nasal mucosa hyperemia, edema, and secretions, and pharyngeal mild hyperemia. If there are no complications, it usually recovers within 5-7 days. 2. Viral pharyngitis, laryngitis and bronchitis According to the inflammatory response caused by the virus to the upper and lower respiratory tract infections, the clinical manifestations can be pharyngitis, laryngitis and bronchitis. Acute viral pharyngitis is mostly caused by rhinovirus, adenovirus, influenza virus, parainfluenza virus, enterovirus, and respiratory syncytial virus. The clinical features are itching and burning in the pharynx, and the pain is not persistent or prominent. When there is pain in swallowing, it often indicates streptococcal infection. Cough is rare. Influenza virus and adenovirus infection may have fever and fatigue. Physical examination of the throat is marked with hyperemia and edema. Submandibular lymph nodes are swollen and tender. Adenovirus pharyngitis may be associated with ocular conjunctivitis. Acute viral laryngitis is mostly caused by rhinovirus, influenza A, parainfluenza, and adenovirus. The clinical features are hoarseness, difficulty speaking, pain when coughing, often fever, pharyngitis or cough. On physical examination, throat edema and congestion can be seen, local lymph nodes are slightly enlarged and tender, and wheezing can be heard. Acute viral bronchitis is mostly caused by respiratory syncytial virus, influenza virus, coronavirus, parainfluenza virus, rhinovirus, adenovirus, etc. The clinical manifestation is cough, no sputum or mucus, accompanied by fever and fatigue. Other symptoms often include hoarseness, non-pleural pain under the sternum. Dry or wet rales can be heard. X-ray chest X-ray showed increased and enhanced blood vessel shadow, but no lung infiltration shadow. Acute bronchitis of influenza virus or coronavirus often occurs in acute episodes of chronic bronchitis. 3. Herpes angina is often caused by Coxsackie virus A, manifested by obvious sore throat, fever, and the course of disease is about one week. Examination showed pharyngeal congestion, gray-white herpes on the surface of the soft palate, palatal pharynx, pharynx and tonsils, superficial ulcers, and blush around. More frequent attacks in summer, more common in children, and occasionally in adults. 4. Pharyngeal conjunctival fever is mainly caused by adenovirus and coxsackie virus. Clinical manifestations include fever, sore throat, photophobia, tearing, and obvious congestion of the pharyngeal and conjunctival membranes. The course of disease is 4-6 days, often occurring in summer and spread during swimming. More common in children. 5. Bacterial pharyngitis-tonsillitis is mostly caused by hemolytic streptococci, followed by Haemophilus influenzae, pneumococcus, staphylococcus and so on. The onset is acute, obvious sore throat, chills, fever, body temperature can reach 39 ℃. Examination showed obvious pharyngeal hyperemia, enlarged tonsils, hyperemia, yellow surface
