However, during the acute phase of the illness or if there are severe complications, it is not recommended to shower or wash the hair.

Under normal circumstances, "Jia Liu" (甲流) refers to Influenza A. Children infected with Influenza A need to be isolated.

Under normal circumstances, "swine flu" refers to influenza A, and "fever" indicates an elevated body temperature. Influenza A is contagious one day before the onset of fever.

When coughing or sneezing, cover the mouth and nose with tissues or towels to prevent droplet transmission.
