Flu basics, prevention, and treatment
Influenza viruses cause flu. The viruses spread from person to person when infected people cough, sneeze, or touch objects. Flu can be mild or severe and can even cause death. Older people, children under 5 (especially children under 2), pregnant women, and people with certain health conditions are at a higher risk for serious complications from the flu.
Flu season usually begins in December and lasts until April or May in the U.S.
What is the best way to prevent the flu in children?
Flu vaccination is the best way to prevent flu infection. All people 6 months and older should get the flu vaccine each year. Healthy children over 2 may get either the shot or the
nasal spray vaccine. Your child’s doctor can help you choose the best option for your child.
When you and your family get the flu vaccine, you're not only protecting yourselves, you're also protecting your community. It’s also important to get the flu vaccine each flu season so the healthcare system isn’t overloaded if there are surges of respiratory syncytial virus (
RSV) and COVID-19.
For
most people, it's best to get the flu vaccine in September or October, but it’s never too late to get the vaccine at any point in the season.
