The flu is caused by several influenza viruses (which are not the same as the virus that causes COVID-19). Most flu outbreaks happen in late fall and winter. 
Getting a flu shot in the autumn can help prevent the virus for the entire flu season. Most people with the flu get better after a few weeks, but they can pass it to other people who are higher risk of health problems, such as babies, pregnant women, older adults, and people with other serious illnesses. Find out the symptoms of the flu and what to do if you get sick.
