Influenza

Influenza is an acute viral infection that spreads easily from person to person in any age group and that can cause serious complications in certain risk groups. In addition to seasonal epidemics, influenza pandemics can occur when a new influenza virus subtype emerges or when an animal influenza virus begins to spread among humans.
