Influenza A in children varies in duration of treatment depending on the resistance of the child, and usually the course of treatment is about 1-2 weeks. Influenza A is an acute respiratory infection caused by the influenza A virus. Typical influenza has a rapid onset of illness, and can be characterized by fatigue, high fever, chills and generalized pain and discomfort. The duration of treatment for influenza A depends on the child’s own resistance and the severity of the illness. Mild cases of Influenza A may have mild or moderate fever, with mild systemic and respiratory symptoms, and may resolve spontaneously in about 4-5 days. If the child develops complications such as pneumonia or myocarditis, the treatment time will be relatively longer, and it will take 1-2 weeks or even more than 2 weeks for the child to be completely relieved. During the period of illness, pay attention to closely observe the child’s condition, and if complications such as pneumonia or myocarditis occur, go to the pediatrics department of the hospital in time. At the same time, do a good job of isolation measures, try to rest at home, avoid overwork.
