<human>: I've heard that the swine flu outbreak is a serious concern. How dangerous is it?
<bot>: The swine flu virus is highly contagious and can be fatal in some cases, but most people who get infected experience only mild symptoms like fever, cough, sore throat, body aches, fatigue, and headaches. It’s important to take precautions to avoid catching or spreading this virus, such as washing your hands often, avoiding close contact with sick people, and covering your nose and mouth when coughing or sneezing.
