Influenza A RNA copies/m3 of air concentrations detected in the swine facilities using two personal bioaerosol samplers.

Personal samples were collected among veterinarians working in swine production facilities that were infected with influenza A (H1N1 or H3N2) virus. Swine veterinarians were called to the swine facilities during a suspected influenza A infection and collected bodily fluids for a diagnosis. Samples were collected at various time during or after this initial evaluation of the infected swine herd. The NIOSH bioaerosol sampler and the PHISH collected samples at a flow rate of 3.5 L/min and 10 L/min, respectively. Total RNA copies/m3 were determined by qPCR. The summary of the data is reported as geometric mean (GM) and geometric standard deviation (GSD).
