I've been hearing a lot about the swine flu. Is there anything I should know about it?

The swine flu is caused by a type of influenza virus called H1N1, which is a strain of influenza that has not been seen before in humans. It was first identified in Mexico in 2009 and spread quickly around the world. Symptoms can include fever, coughing, sore throat, body aches, fatigue, chills, vomiting, diarrhea, and sometimes a rash. In some cases, people may also have difficulty breathing or be hospitalized for severe pneumonia.
