=Swine Flu/ H1N1 Influenza Type A= In April 2009, this very harmful illness appeared in the United States. Originally, only pigs could get infected with this disease. It spreads to people the same way it spreads from hog to hog. People and pigs got this disease by direct contact or droplets holding the virus in the air after a pig sneezed. Pigs are very similar to humans physiologically so when pigs live closely to humans, some microbes that can infect pigs are able to change or mutate into strains that people can catch. Infected people can also infect pigs so it goes both ways.
