[Clinical features of influenza in children].

All age groups in a population become ill with fever, respiratory tract involvement and systemic symptoms by influenza A virus. An understanding of the differences in the clinical features of influenza between children and adults may be helpful for the diagnosis and the treatment of influenza in children. This paper summarizes the clinical features and the disease burden of influenza in children, the currently available rapid diagnosis kits for influenza A and B virus, the treatment of influenza A and B infections by anti-influenza medications(amantadine and zanamivir), the prophylaxis of influenza A and B infections by anti-influenza medications and vaccines, and the prognosis.
