Although influenza A is capable of significant impacts in swine production, including the possibility of transmission between pigs and people, little is known of the exposure risks for viral transmission at the time of active outbreaks. We performed a systematic sampling of aerosols and surfaces for the presence and persistence of influenza A viruses during outbreaks in swine herds, and found detectable virus in aerosols and on surfaces including the isolation of influenza from air samples. These findings suggest that workers entering swine barns during active influenza infection in pigs could be at risk of zoonotic infection and that programs to ensure adequate respiratory protection at such times could reduce worker risk. Findings from the study will be helpful for the industry to develop evidence-based guidelines to minimize the impact of influenza A infections on swine production and worker health.
