    The Health Bureau stated that according to the latest notification from the mainland health department, a total of 2 cases of human infection with H9N2 avian influenza were confirmed in Hunan and Guizhou provinces, and residents were urged to avoid contact with birds and pay attention to personal and food hygiene.
    According to the report, one of the patients is a 5-year-old boy who lives in Yueyang City, Hunan Province. He developed symptoms on April 26, 2022, and was diagnosed on June 2, 2022. His condition is mild and there were live poultry market activities before the onset. history. The other patient is a 2-year-old boy who lives in Bijie City, Guizhou Province. He developed symptoms on May 8, 2022, and was diagnosed on June 1, 2022. His condition is mild and he has a history of live poultry market activity before the onset.
    Influenza viruses are mainly divided into three types: A (A), B (B), and C (C). Type A can cause a worldwide pandemic, so it is particularly important; type B generally only causes local epidemics, and type C often only causes sporadic case. Influenza A virus has two main antigens on the surface of hemagglutinin ( H emagglutinin, H) and neuraminidase ( N euraminidase, N); hemagglutinin has 1 to 16 types, and neuraminidase has 1 to 16 types. Type 9. Influenza A viruses are named after different combinations of H and N, such as H1N1 in the 2009 pandemic and now H7N9, H10N8, etc. Influenza A is important because the H and N antigens are easy to change to produce new subtypes; but humans are not immune to the new subtypes, so they often cause different degrees of prevalence; when a brand new influenza virus appears in humans At that time, because human beings have no resistance at all, there is a possibility of a worldwide pandemic. The reasons for the generation of new influenza viruses are the recombination of the genes of human influenza viruses and non-human influenza viruses (such as avian influenza viruses), or the re-emergence of old subtype strains, or the change of host specificity of animal influenza viruses.
    To prevent influenza A infection, the Health Bureau urges the public to pay attention to the following:
    • Avoid going to markets and farms where there are many people and where there are outbreaks of avian influenza A, where poultry is sold or displayed;
    • Avoid contact with sick people, birds or other animals and their secretions and excrement; if there is contact, wash hands immediately;
    • Do not eat undercooked poultry meat, offal, blood products and eggs;
    • Pay attention to personal hygiene and wash your hands frequently;
    • If you have symptoms such as fever, cough, and difficulty breathing, you should wear a mask, seek medical attention as soon as possible, and report your travel history and animal contact history to the doctor.
