The H3N2 infection (respiratory infection) is brought on by the influenza virus. Both animals and birds can contract the virus. It has undergone several strains of mutation in birds and other animals especially pig. H3N2 is a type of Influenza A virus usually leading to localised infections. It usually circulates in pigs but when found in humans it is called a variant virus. According to the Centres for Disease Control (CDC) and the World Health Organization, a virus which has undergone significant mutation is a potential agent for human to human transmission leading to uncontrolled replication and spread.
