CDC: Influenza A(H1N1)pdm09 Virus among Healthy Show Pigs, United States

[Click on link for full document] Abstract Within 5 months after the earliest detection of human influenza A(H1N1)pdm09 virus, we found molecular and culture evidence of the virus in healthy US show pigs. The mixing of humans and pigs at swine shows possibly could further the geographic and cross-species spread of influenza A viruses. Gregory C. GrayComments to Author , Jeffrey B. Bender, Carolyn B.
