What Is the Flu?

Influenza (the flu) is a contagious respiratory illness caused by influenza viruses. Experts believe that flu virus “droplets” are spread when a person coughs, sneezes or talks and those flu germs are inhaled by others. Sometimes a person can be infected by touching a surface or object that has the flu virus on it and then touching their own mouth or nose.
