H1N1 is an influenza caused by strains of virus. These viruses usually infects pigs and is common among pigs in Midwestern US, Mexico, Canada, South America, Europe, Kenya, Mainland China, Taiwan, Japan and other parts of Asia.
Though there are reports of people in proximity to pig are infected, the chances of transmission of the swine flu virus from pigs to humans is most uncommon. Only about fifty such local transmissions have been reported for the past 60 years.
Unlike the earlier cases, the resilience and quick spreading of the current strain, a new one of influenza A virus subtype H1N1, of the microbe is a worrying factor and it is still worst as it spreads from human-to-human contact. There is now a question on our level of immunity to resist the infection.
