Answer 1

Swine flu is caused by a strain ofinfluenza 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 properly cooked pork products. Swine flu is very contagious
