The flu is a highly contagious respiratory illness caused by influenza viruses. Symptoms can include fever, chills, coughing, sore throat, runny or stuffy nose, body aches, headaches, and fatigue. It can be serious for some people, especially young children, the elderly, and those with certain health conditions. People who are at risk of developing complications from the flu should get vaccinated as soon as possible.
