  • China - Macao announces new avian flu H9N2 case in Guangdong province - July 31, 2018

    Guangdong confirmed a case of human infection with H9N2 avian influenza


    source: Health Bureau (SS) Release date: July 31, 2018, 19:37
    The Health Bureau received a notification from the Mainland Health Department today (July 31) that a case of human infection with H9N2 avian influenza was confirmed in Guangdong Province. According to the report, the patient is a 24-year-old woman and currently lives in Shenzhen. Symptoms appeared on July 21 and were admitted to hospital on July 23. The condition is now mild.
    Influenza viruses are classified 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 causes only local epidemics, and Type C usually causes only sporadic cases. . Influenza virus surface with hemagglutinin ( H emagglutinin, referred to as H) and the enzyme neuraminidase enzyme ( N euraminidase, referred to as N) two major antigens; total 1 hemagglutinin type ~ 16, 1 ~ Total neuraminidase Type 9. Influenza A viruses are named after a combination of different H and N, such as the 2009 pandemic H1N1 and the current H7N9, H10N8 and so on. The reason why influenza A is important is that H and N antigens are easy to change to produce new subtypes; but humans are not immune to new subtypes, so they often cause different degrees of prevalence. When a new type of flu virus appears in humans, there is a possibility of a worldwide pandemic because people are completely unresisting. The reason for the emergence of the new influenza virus is the recombination of the genes of the human flu virus and the non-human flu virus (such as the avian flu virus), or the re-emergence of the old subtype strain, or the animal flu virus changes the host traits.
    To prevent the spread of influenza A, the Health Bureau appeals to the public to pay attention to the following matters:
    • Avoid places where there are many people, and where there are people selling or displaying birds in markets such as areas where people are infected with the Avian Influenza A;
    • Avoid contact with patients, birds or other animals and their secretions, excretions; if contact, wash hands immediately;
    • Do not eat birds, viscera, blood products and eggs that have not been thoroughly cooked;
    • Pay attention to personal hygiene and wash your hands often;
    • If you have symptoms such as fever, cough, or difficulty breathing, wear a mask, seek medical attention as soon as possible, and detail the history of travel and animal contact to the doctor.
