The flu is more than just a bad cold. Influenza, also known as the flu, is a contagious and sometimes severe disease caused by viruses that infect the nose, throat, and sometimes the lungs. Influenza can cause anything from mild symptoms to severe illness that can result in hospitalization or death.
If you have the flu, you might have these symptoms:
The flu virus is spread mainly by tiny droplets made when people with the flu cough, sneeze, or talk. These droplets can land in the mouths or noses of people who are nearby. Less often, a person can get influenza by touching a surface or object that has the virus on it and then touching their own mouth, nose, or even their eyes.
The best way to prevent influenza is to get vaccinated each year. Everyone 6 months and older needs a flu vaccine. Most insurance plans cover the cost of a flu vaccine.

Treatment can make symptoms milder and reduce the risk of other health complications and death. Talk to your health care provider about flu medications.
