Over the next few months, you might notice more classmates than usual absent from school. It’s that time of year again: flu season.
Flu season in the United States usually lasts from October through March. Last flu season was one of the worst in recent years, according to the U.S. Centers for Disease Control and Prevention. Millions of Americans caught the flu. In most cases, people were treated by doctors and got better in a couple of weeks. In very severe cases, people had to go to the hospital.
Doctors don’t yet know how bad this year’s flu season will be. But they do know how the illness spreads—and what you can do to protect yourself.
