title: A surveillance of human influenza virus in swine in southern Taiwan.
abstract: From September 1970 to December 1971, samples were taken monthly from farm pigs, piglets and abattoir pigs in Southern Taiwan for virus isolations and serologic studies. A total of 10 strains of hemagglutinating agent were isolated in January and July 1971, following 2 epidemics of human influenza occurring in December 1970 and June 1971, respectively. Three strains were antigenically confirmed as influenza A similar to A/Hong Kong/68 virus.
