<human>: I've heard a lot of talk about swine flu. What is it?
<bot>: Swine flu is a type of influenza virus that infects pigs and humans. It is a highly contagious disease that can spread from person to person through coughing, sneezing, or physical contact with an infected person. Symptoms include fever, chills, cough, sore throat, body aches, fatigue, headache, and sometimes vomiting and diarrhea. The most common treatment for swine flu is rest, fluids, and over-the-counter medications such as ibuprofen or acetaminophen to reduce fever and pain.
