You can still get infected by other subtypes of influenza viruses after you get well from influenza A.
Influenza A is influenza A, a type of influenza. The surface antigenicity of influenza A viruses varies greatly, and according to the antigenic differences, influenza A can be categorized into 18 H subtypes and 11 N subtypes, of which H5N1, H9N2, H7N9 can directly infect humans. And there is a lack of immunoprotection between subtypes, and repeated infections can occur.
Therefore, after influenza A is well, it is also necessary to take protective measures to avoid infection with other subtypes of influenza A viruses. At present, the most effective way to prevent human influenza from becoming pathogenic and epidemiologic is still vaccination, which is also the basic measure to prevent influenza. In endemic areas, we can choose the appropriate vaccine to be vaccinated to establish an immune barrier to avoid infection by the pandemic strain as much as possible.
In addition, we need to wear masks, avoid close contact with suspected patients, and pay attention to personal hygiene, ventilation and disinfection.
