The h1n1 flu virus is a respiratory disease caused by type influenza viruses. spread of the h1n1 flu virus is thought to be happening in the same way that seasonal flu spreads. flu viruses are spread mainly from person to person through coughing or sneezing (i.e., droplet spread). sometimes people may become infected by touching contaminated objects or surfaces with flu viruses on it and then touching their mouth or nose.influenza viruses can be transmitted from pigs to people and vice versa through coughs and sneezes; however, there is no risk from proximity to healthy pigs. because humans can also spread the disease to pigs, individuals with influenza symptoms should avoid close contact with pigs to reduce the risk of introducing a new influenza virus into domestic swine populations.
