swine-flu-pig.jpgSwine flu is caused by a strain of influenza virus that usually only infects pigs. Unlike typhus, which can be transmitted by lice or ticks, transmission usually occurs from person to person, not animal to person.

You can't catch swine flu from eating pork products.

Swine flu is very contagious. The disease is spread through saliva and mucus particles. People may spread it by:

  • sneezing
  • coughing
  • touching a germ-covered surface and then touching their eyes or nose
