Influenza, commonly known as the flu, is a contagious respiratory illness caused by influenza viruses that can cause fever, cough, sore throat, runny nose, muscle or body aches, and fatigue. These viruses spread through droplets released into the air when someone who is sick coughs, sneezes, or talks. While most people recover from the flu within a few days to less than two weeks, some people are at high risk of developing serious complications, such as pneumonia, bronchitis, or sinus and ear infections.
There are several ways to avoid getting the flu. The most important step is to get vaccinated each year. The flu vaccine is safe and effective, and it is the best way to protect yourself and others from the flu. Other ways to avoid the flu include washing your hands frequently with soap and water, avoiding touching your face, and staying home if you are sick.
