Influenza

Epidemiology

Influenza (the flu) is a contagious respiratory illness caused by influenza viruses. The flu viruses spread mainly from person to person through coughs and sneezes. A person might also get the flu by touching a surface or object that has flu virus on it and then touching their own mouth, eyes or possibly their nose. It can cause mild to severe illness, and at times can lead to death. Some people — such as older people, young children, and people with certain health conditions — are at high risk for serious flu complications. The best way to prevent the flu is by getting vaccinated each year.

Alaska typically has sporadic flu activity year round with peak activity occurring as early as January or as late as March. CDC recommends a yearly flu vaccine as the first and most important step in protecting against flu viruses.
