<human>: I've heard that the flu is going around. What are the symptoms and how can I prevent it?
<bot>: The main symptom of the flu is a fever, chills, cough, sore throat, body aches, fatigue, and runny or stuffy nose. To help prevent the flu, you should wash your hands often with soap and water for at least 20 seconds, avoid touching your face, cover your mouth when coughing and sneezing, and stay home from work or school if you feel sick.
