The flu is a highly contagious illness caused by viruses that can cause mild to severe illness. It can spread easily from person to person through coughing, sneezing and contact with objects or surfaces contaminated with the virus. Symptoms of the flu include fever, chills, body aches, fatigue, sore throat, congestion, runny nose and headaches. People at risk for more serious complications should seek medical attention immediately if they have these symptoms.
