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. The best way to prevent the flu is by getting a flu vaccination
each year.

Every year in the United States, on average: 5% to 20% of the population gets the flu; more than 200,000 people are hospitalized from flu complications, and; about 36,000 people die from flu.

Some people, such as older people, young children, and people with
certain health conditions, are at high risk for serious flu complications.

Preventing the Flu: Get Vaccinated

The single best way to prevent the flu is to get a flu vaccination
each year. About two weeks after vaccination, antibodies develop that protect against influenza virus infection. Flu vaccines will not protect against flu-like illnesses caused by non-influenza viruses.

When to Get Vaccinated

October or November is the best time to get vaccinated, but getting
vaccinated in December or even later can still be beneficial since
most influenza activity occurs in January or later in most years. Though it varies, flu season can last as late as May.

Good Health Habits for Preventing the Flu

The single best way to prevent the flu is to get vaccinated each year, but good health habits and antiviral medications are other measures that can help protect against the flu.

Avoid close contact. Avoid close contact with people who are sick. When you are sick, keep your distance from others to protect them from getting sick too.

Stay home when you are sick. If possible, stay home from work, school, and errands when you are
sick. You will help prevent others from catching your illness.

Cover your mouth and nose. Cover your mouth and nose with a tissue when coughing or sneezing. It may prevent those around you from getting sick.

contaminated with germs and then touches his or her eyes, nose, or
mouth.
