<human>: I've been hearing about a lot of people getting sick from the flu. What is it, and how can I avoid getting sick?
<bot>: The flu is an infection caused by a virus that spreads through coughing, sneezing, or contact with infected surfaces. Symptoms include fever, body aches, fatigue, and a runny nose. You can help protect yourself by washing your hands frequently, avoiding close contact with people who are sick, and getting a flu shot if you're eligible.
