Is influenza A still contagious after the fever goes down?

Influenza A may still be contagious after the fever is gone, and the absence of fever does not mean that the virus is completely gone.
Influenza A is mainly caused by influenza A virus infection, and fever may appear after infection. After cooling treatment, the body temperature can drop gradually, only the fever symptoms have been controlled, not the disease has been cured. The influenza A virus is still present in the body, but the titer or amount has decreased.
Although fever does not continue to occur at this time, as long as the virus is still present and active, there is a possibility of transmission. The virus can be transmitted through respiratory droplets and other means to uninfected people. It is therefore necessary to continue isolation and treatment to avoid widespread transmission.
