Abstract

An H1N2 influenza A virus was isolated from a pig in the United States for the first time in 1999 (A. I. Karasin, G. A. Anderson, and C. W. Olsen, J. Clin. Microbiol. 38:2453-2456, 2000). H1N2 viruses have been isolated subsequently from pigs in many states. Phylogenetic analyses of eight such viruses isolated from pigs in Indiana, Illinois, Minnesota, Ohio, Iowa, and North Carolina during 2000 to 2001 showed that these viruses are all of the same reassortant genotype as that of the initial H1N2 isolate from 1999.
