Natural history of influenza in swine in Hawaii: prevalence of infection with A/Hong Kong/68 (H3N2) subtype virus and its variants, 1974-1977. 1979

G D Wallace

From September 1974 to January 1978, about 25% of 254 swine farms, studied on four of six Hawaiian islands, had swine with antibody to A/Hong Kong/68 (H3N2) subtype of influenza virus. Of 290 swine 2 to 5 years of age in a single herd, 72% had antibody. Antibody titers were consistently higher to A/England/42/72 and A/Port Chalmers/1/73 antigens than to A/Victoria/3/75 or A/Hong Kong/1/68 antigen. Few swine had antibody to the A/Hong Kong/68 antigen. Antibodies to H3N2 and Hsw1N1 subtype of virus persisted at high titer in the same animals for more than 3 years; however, titers to the Hsw1N1 subtype were considerably higher. The occurrence of H3N2 infection in swine appeared shortly after the occurrence of the same H3N2 variant in human population. To date there is no evidence that the H3N2 subtype has become established in swine in Hawaii.

D009980	Influenza A virus	The type species of the genus ALPHAINFLUENZAVIRUS that causes influenza and other diseases in humans and animals. Antigenic variation occurs frequently between strains, allowing classification into subtypes and variants. Transmission is usually by aerosol (human and most non-aquatic hosts) or waterborne (ducks). Infected birds shed the virus in their saliva, nasal secretions, and feces.

D006254	Hawaii	A group of islands in Polynesia, in the north central Pacific Ocean, comprising eight major and 114 minor islands, largely volcanic and coral. Its capital is Honolulu. It was first reached by Polynesians about 500 A.D. It was discovered and named the Sandwich Islands in 1778 by Captain Cook. The islands were united under the rule of King Kamehameha 1795-1819 and requested annexation to the United States in 1893 when a provisional government was set up. Hawaii was established as a territory in 1900 and admitted as a state in 1959. The name is from the Polynesian Owhyhii, place of the gods, with reference to the two volcanoes Mauna Kea and Mauna Loa, regarded as the abode of the gods.
