    Flu Facts

    Influenza (the flu) is a contagious respiratory illness caused by influenza viruses that infect the nose, throat and lungs. It can cause mild to severe illness, and at times can lead to death. The best way to prevent catching and spreading the flu (influenza) is to get a vaccine each year.

    What is the "Stomach flu?"
    Although often used to describe illnesses with nausea or diarrhea, the "stomach flu" isn't influenza. These symptoms are commonly caused by gastroenteritis.

    How serious is it, and who is at most risk?

    Each year in the U.S., about 200,000 people are hospitalized due to flu complications; most are 65 years and older; children 5 years old and younger make up 20,000 of those hospitalized.

    Highest risk:

    • Elderly
    • People with chronic health conditions

    Is there a vaccine, and who should get it?

    The seasonal flu vaccine is available now. Most adults and children – except infants under 6 months – should be vaccinated to reduce the chance of getting the flu and help stop the spread of the virus. If you have an egg allergy, consult your physician before receiving a flu vaccine.
