Influenza Title

Influenza, or the flu, is a contagious respiratory illness caused by influenza viruses. Flu is spread through tiny droplets when a person coughs, sneezes, or talks. Although less common, a person can also get the flu by touching a contaminated surface or object, then touching their own mouth, nose, or eyes. Flu can cause mild to severe illness, which can result in hospitalization or death. The best way to prevent the flu is to get a flu vaccine each year.
