The flu is a contagious disease caused by influenza germs. Flu can cause mild to serious illness, and can sometimes lead to hospitalization or even death.

The best way to prevent the flu is to get a flu shot. With COVID-19 still spreading, it’s even more important to get a flu shot so you can stay as healthy as possible. 

Need a Covid-19 shot AND a flu shot? It's safe to get both shots at the same time. You do not need to wait between shots.

Flu is spread from person-to-person by coughing, sneezing, talking or singing.

How to Stop Flu

Everyone over 6 months of age should get a flu shot each year. It's never too early or too late to get one. Flu vaccine is very safe.

You should also stay home if you’re sick. Cover coughs and sneezes, and wash your hands frequently with soap and water or use hand sanitizer to avoid getting sick.

Problems from Flu

Some people are more likely to have serious problems from the flu that can lead to hospitalization or even death:

  • People with chronic medical conditions like asthma, diabetes and heart disease
  • Anyone under age 5 or over 65
  • Pregnant women

If you have one of these conditions it is especially important to get vaccinated against the flu. If you think you have the flu, contact your health care provider.

Stay Home If You're Sick

If you think you have the flu or any other respiratory illness, you should stay home to keep it from spreading.
