I've been hearing about a lot of people getting sick from the flu. What is it, and how can I avoid getting sick?

The flu is a highly contagious respiratory illness caused by influenza viruses. Symptoms include fever, chills, coughing, sore throat, runny or stuffy nose, body aches, headache, fatigue, and sometimes vomiting and diarrhea. It can last for up to a week and can be serious for some people, especially those with underlying health conditions. To help prevent the spread of the flu, wash your hands often, cover your mouth when coughing or sneezing, stay home if you are feeling ill, and avoid contact with people who have the flu.
