The following position statement is provided for historical purposes only.

This statement replaced the 2009 position statement on Pandemic H1N1 2009 influenza, and has now been replaced by the current AASV position on Influenza A Viruses approved by the Board of Directors on April 3, 2018.

AASV Position Statement: Influenza A Viruses

Influenza A viruses (IAVs) are a cause of respiratory disease in swine that can decrease pig performance, negatively affect health, and are sporadically transmitted to and from humans. The emergence of the pandemic (H1N1) 2009 influenza virus reminded us of the importance of cross-species transmission of influenza viruses. The continuous presence of a diverse array of IAVs in the swine population makes it apparent that reducing the burden of disease caused by IAV is important.

It is the position of the AASV that we

- promote research and surveillance programs for IAVs with the goal of discovering effective methods to control disease through farm-specific efforts, including but not limited to improved vaccines;

- encourage veterinarians and producers to review the IAV health plan including the vaccination of swine with approved IAV vaccines according to label directions and based on veterinary recommendation for strain matching;

- support the recommendation that people working with swine take all available precautions, including vaccination (with their human health professional’s approval), to prevent infection with influenza; and

- recommend pork producers, swine veterinarians and diagnostic laboratories actively participate in IAV surveillance programs that provide information regarding IAV evolution and epidemiology.
