Indirect transmission of influenza A virus (IAV) in swine is poorly understood and information lacking on levels environmental exposure encountered by people during outbreaks IAV barns. We characterized viral load, viability persistence air surfaces was detected pigs, from five confirmed with 48% (47/98) oral fluid, 38% (32/84) pen railing 43% (35/82) indoor samples testing positive RT-PCR. isolated fluids yielding a mixture subtypes (H1N1, H1N2 H3N2). Detection RNA sustained the maximum estimated between 7 11 days reported onset. Our results indicate that swine, aerosols barns contain significant potentially representing an hazard to both people.
