What is swine flu?猪流感是什么

It is a contagious respiratory disease of pigs caused by type A influenza viruses. Pigs are hit by regular outbreaks. There are many different types of swine flu and the current cases involve the H1N1 strain of type A influenza virus.
How do humans catch it?

While people do not normally catch it, humans can contract the virus, usually if they have been in close contact with pigs. It is also possible for the constantly changing infection to spread from person to person, which has happened in the latest outbreak. Experts believe it spreads in the same way as seasonal flu - through coughing and sneezing.
