Swine flu H3N2v spreads from pigs to humans, humans to humans

A new strain of swine flu, H3N2v, is infecting people in the US. From July 12 to Aug 9, 2012, 113 people were infected in Indiana, 30 in Ohio, and one each in Hawaii and Illinois. Most of the infected patients are children, and all had been in close contact with pigs, mainly at agricultural fairs. H3N2v, also known as Type A H3N2, has the M gene from the human H1N1 flu virus, which makes it easier for the virus to infect and be transmitted among humans. The virus is normally spread from pigs to humans. Human-to-human transmission is possible, but less likely than with seasonal flu. Symptoms of H3N2v infection include fever, aches, cough, runny nose, nausea and diarrhea. A vaccine is currently in development.
