Healthy Show Pigs Showed Evidence of H1N1 Flu in 2008, 2009

21 August 2012

US - Researchers collaborating across the country report that they detected evidence of the human influenza A(H1N1)pdm09 virus in apparently healthy show pigs within five months of its first detection.

Within five months after the earliest detection of human influenza A(H1N1)pdm09 virus – in 2008 and 2009 – Gregory C. Gray of the University of Florida and co-authors report that they found molecular and culture evidence of the virus in healthy show pigs in the US.

In a paper ahead of print in Emerging Infectious Diseases, they add that the mixing of humans and pigs at shows could further the geographic and cross-species spread of influenza A viruses.
