What is Swine Flu - H1N1 Virus ?
Swine flu, now called H1N1 influenza A, is a type of flu virus. The virus is thought to have originated from Mexico, but has since spread globally. Although it was previously known as swine flu, it is not contracted from pigs or by eating pork. It was renamed H1N1 influenza A to avoid people making a connection to pigs. It is a human influenza virus and is being spread by people. It is thought to be a combination of three different flu viruses - swine flu, bird flu and human flu. The new strain is extremely contagious and is quickly spreading across the globe.
