Human swine flu is a respiratory infection caused by the swine flu virus. When people are infected with swine influenza virus, they develop flu-like symptoms. The use of Tamiflu (Oseltamivir) is effective in the early stage of virus infection, but it is resistant to Amantadine and Rimantadine. Preventive measures are mainly to avoid contact with influenza-like patients and maintain personal hygiene, etc. If you suspect swine flu infection after entering the country, you should wear a mask at home or when seeking medical treatment, and explain your travel history to your doctor. Symptoms of swine flu The symptoms of human swine flu infection are similar to those of the flu, with patients experiencing fever, cough, fatigue, and loss of appetite. In terms of prevention, there is no need to pile on the human flu vaccination at this stage, as the seasonal flu vaccine is not effective in preventing swine flu. The correct approach is to practice good personal hygiene, get enough sleep, exercise regularly, reduce stress, and get enough nutrition; wash your hands regularly, especially after touching public objects before touching your eyes, nose and mouth; cover your mouth and nose with tissues when sneezing and coughing; keep ventilation indoors, etc. The main manifestations of the swine flu cases found in the United States were sudden onset of fever, cough, muscle pain and fatigue, with some patients also showing diarrhea and vomiting; the cases found in Mexico also showed symptoms such as red eyes, headache and runny eyes. There are many predisposing factors that cause the occurrence and prevalence of swine flu, which can be broadly summarized into 3 aspects: first, human factors, second, weather factors, and third, environmental factors. Swine influenza symptoms: human infection with swine influenza is caused by swine influenza virus The disease has a high incidence, incubation period of 2-7 days and a disease duration of about 1 week. At the beginning of the disease, the sick pigs suddenly become feverish, have poor spirit, lose or lose appetite, often lie down together, are reluctant to move, have difficulty in breathing, cough fiercely, and have mucus coming out of their eyes and nose. If the treatment is not timely during the onset, it is easy to complicate bronchitis, pneumonia and pleurisy, which will increase the death rate of pigs. How to prevent swine flu? The human influenza case is associated with an animal influenza virus, and the virus that has been confirmed in the laboratory to have caused the outbreak is the swine influenza virus subtype A/H1N1, a new swine influenza virus that has never been seen in humans or pigs before; the human swine influenza outbreak is occurring in multiple communities; and the people who develop the disease are mostly young adults, rather than those who are susceptible to seasonal influenza –the elderly and children, which is very similar to human avian influenza. WHO is highly concerned about this human swine flu outbreak in Mexico and the United States. Swine flu symptoms: human swine flu is caused by the swine flu virus Pathological changes of swine flu are mainly in the respiratory organs. The mucous membranes of the nose, pharynx, larynx, trachea and bronchi are congested, swollen and covered with sticky fluid on the surface, and the small bronchi and fine bronchi are filled with foam-like exudate. The thoracic and pericardial cavities accumulate large amounts of plasma mixed with fibrin. Lesions of the lungs often occur in the dorsal and basal parts of the apical, cardiac, intermediate, and diaphragmatic lobes, with distinct boundaries with the surrounding tissues, ranging in color from red to purple, collapsed, firm, and tough like leather, with an enlarged spleen and enlarged juicy cervical, mediastinal, and bronchial lymph nodes. Can swine influenza virus be transmitted between people? There have been confirmed cases of interpersonal transmission of swine influenza virus, which is similar to seasonal influenza, usually through coughing and sneezing of the infected person. Is there an anti-swine flu vaccine? There is currently only an anti-swine flu vaccine for pigs, not specifically for humans. As of now, the common anti-swine flu vaccine is not significantly effective against swine flu in humans. Swine flu symptoms: Human infection with swine flu is caused by the swine flu virus Can I get swine flu from eating pork? The swine flu virus is afraid of high temperatures, so you will not get swine flu from eating cooked pork. Pork heated to 71 degrees Celsius will kill the swine flu virus, and people will not get swine flu from eating pork or pig products. There is no specific drug for human infection with swine flu. There are four anti-influenza drugs commonly used, but the mutant virus has been clinically shown to be resistant to two of them. Treatment: resistant to Amantadine and Rimantadine. Use Tamiflu capsules (Roche) and Rimantadine spray (Glaxo).
