I've been hearing about the new swine flu. Is it really dangerous?

The swine flu is a type of influenza virus that can infect humans and animals, including pigs. It was first identified in 2009 and has since spread worldwide. Symptoms can include fever, coughing, sore throat, fatigue, body aches and sometimes vomiting and diarrhea. In some cases, people have also reported difficulty breathing or pneumonia. The World Health Organization (WHO) says the disease is mild for most people but can be more serious for others, especially those with underlying health conditions. The CDC recommends getting a flu shot if you haven't already.
