I've been hearing a lot about the swine flu. What's going on?

The swine flu is a new strain of influenza that was discovered in 2009. It's caused by a virus called H1N1, which is similar to the viruses that cause seasonal flu. Symptoms include fever, coughing, sore throat, body aches, fatigue and chills. Most people recover from it without any complications, but some people can develop more serious illnesses such as pneumonia or even death.
