Influenza Virus Surveillance in Coordinated Swine Production Systems, United States.

ABSTRACT: To clarify the epidemiology of influenza A viruses in coordinated swine production systems to which no animals from outside the system are introduced, we conducted virologic surveillance during September 2012-September 2013. Animal age, geographic location, and farm type were found to affect the prevalence of these viruses.
