The flu is a contagious respiratory illness caused by influenza viruses. It can cause mild to severe illness, and at times can lead to death.
People who have the flu often feel some or all of these symptoms:
Runny or stuffy nose
Sometimes diarrhea and vomiting
* Not everyone with flu will have a fever
Preventing the Flu
Get a Flu Vaccine
The CDC recommends a flu vaccine for everyone 6 months of age and older.
The flu vaccine can reduce flu illnesses, doctors' visits, and missed work and school due to the flu.
Take Preventative Actions
Avoid contact with sick people, cover your nose and mouth with a tissue when coughing or sneezing, wash your hands often, and avoid touching your eyes, nose, and mouth.
