As of the evening of the 6th, the sudden onslaught of H7N9 avian influenza has led to 18 infections and 6 deaths. Bird flu is coming, how should the public properly view the awareness and do the necessary protective measures? Will H7N9 repeat the “SARS” epidemic? ”In the spring, 10 years after the SARS epidemic, H7N9 avian influenza has arrived. There is no evidence that H7N9 is contagious and is circulating, and there is no trend of a pandemic soon. H7N9 is a completely different virus from SARS, and the likelihood of it spreading like SARS is extremely low. According to information released by the World Health Organization, it is still unknown whether the H7N9 virus will cause a pandemic. Other influenza viruses of animal origin have occasionally infected humans, but have not caused pandemics. No human-to-human transmission has been detected in the H7N9 outbreak. No epidemiological link has been found between confirmed cases, and all close contacts of the cases have been placed under medical observation and no abnormalities have been found. How to eat poultry, meat and eggs to be safe? The bird flu has cooled down the poultry business, and meat, eggs and other foods have also been affected. How can poultry, meat and eggs be eaten to ensure dietary safety? ”To ensure dietary safety, you should not eat animals infected with the virus and do not consume raw meat.” The World Health Organization recommends that food be cooked in such a way that raw and cooked food is separated, and ensure that imported meat and eggs are adequately heated. Careful hand washing is needed after contact with raw meat and cleaning and disinfecting utensils that have come into contact with raw meat. The National Center for Food Safety Risk Assessment suggests that avian influenza viruses are generally heat-sensitive and resistant to low temperatures, and can be inactivated by heating at 65°C for 30 minutes or boiling (100°C) for more than 2 minutes. The virus can survive for 1 week in feces at lower temperatures and 1 month in water at 4°C. As a precaution, the National Center for Food Safety Risk Assessment recommends that, although the source and mode of transmission of H7N9 avian influenza virus infection cannot be determined, one should not touch or eat sick (dead) poultry or livestock meat, and not buy fresh, live or frozen poultry or livestock and their products without quarantine certificates; raw poultry, livestock meat and eggs must be cooked thoroughly; in the process of food processing and consumption, one must separate raw and cooked food to avoid Cross-contamination, handling raw poultry, livestock and meat of the board, knives and containers can not be used for cooked food; to maintain good personal hygiene habits, do not drink raw water; keep hand hygiene, wash your hands often. Wash your hands before, during and after making food, before and after meals, and after handling raw poultry and animal meat and raw eggs. What should I do if I have cold symptoms? ”The incubation period for human H7N9 avian influenza infection is generally within 7 days. Patients generally show flu-like symptoms, such as fever, cough, less sputum, which can be accompanied by headache, muscle aches and general discomfort.” The Health and Family Planning Commission recently issued a treatment plan for human H7N9 avian influenza (version 1, 2013) points out that patients with severe human H7N9 avian influenza develop rapidly, manifesting as severe pneumonia, with body temperature mostly persisting above 39°C, respiratory distress, which can be accompanied by hemoptysis; it can progress rapidly to acute respiratory distress syndrome, mediastinal emphysema, sepsis, shock, impaired consciousness and acute kidney Acute kidney injury, etc. ”If cold-like symptoms appear, especially in patients who have been in contact with birds, it is important to seek medical attention in a timely manner to achieve early detection, early diagnosis and early treatment so as not to miss the best time for treatment.” Hospital nosocomial cross-infection prevention and control is very important. Minor illnesses should try to go to local medical institutions, do not concentrate on large hospitals; medical institutions to do patient triage, fever clinic admission of patients after timely screening; doctors to strengthen their own protection, especially respiratory, infectious and other doctors in contact with fever patients to wear masks, good protection.
