Seasonal influenza is an acute viral infection that is spread by person-to-person transmission. Influenza, commonly referred to as the flu, circulates worldwide and can affect anyone in any age group, although annual epidemics peak during winter in temperate climates. Seasonal influenza can be type A, B, or C. Type A influenza viruses are considered to be the most virulent of the three types, and can be further classified by serotype based on antibody response to the virus.
