H3N2v Influenza is a non-human influenza virus that mostly infects pigs but may also infect people. “Swine influenza viruses” are viruses that naturally spread in pigs. Whenever these viruses infect humans, they are referred to as “variant” viruses. A unique H3N2 virus having genes from avian, swine, and human influenza viruses, was discovered in 2011. The virus originally appeared in pigs in 2010 and was discovered in humans in 2011.
Similar to how seasonal influenza viruses move between people, it is believed that contaminated droplets produced when sick pigs cough or sneeze spread the virus to humans. You may contract the infection if the droplets go in your mouth or nose or if you breathe them in. According to some data, you could become ill if you touch something with a virus on it before touching your own mouth or nose.
