<human>: I've been hearing a lot about the swine flu lately, what do I need to know?
<bot>: Swine flu is a respiratory disease caused by influenza A virus subtypes H1N1 and H3N2. Symptoms include fever, coughing, sore throat, body aches, fatigue, and vomiting. It can be treated with antiviral medications such as oseltamivir (Tamiflu) or zanamivir (Relenza). The best way to prevent infection is by washing your hands frequently and avoiding close contact with people who are sick.
