Influenza A is a virus that can be transmitted through the air from infected pigs and by pigs rubbing their noses together. Although there have been cases where outbreaks have been documented without any new pigs being introduced, implying that the disease has alternate routes of infection. Studies have found a relation between effected farms in a dense area. The objective of this study is to find out if aerosol transfer of influenza A was possible by testing aerosol from highly infected farms. The study was done in two parts, part one consisted of taking air samples at the hog farm that was infected, and the second phase was done taking samples at varying distances down wind from the farm. In phase one 15 air samples were taken for 30 minutes each. For phase two samples were taken in from the exhaust from the barns, and half a mile and a mile down the road for a total of sixty samples. During the first visit all of the air samples tested positive, the second visit found 6 of 15 samples from inside the barn tested positive while 2 of 15 samples from outside the barn tested positive. This research shows that it is possible for infected farms to spread influenza A throughout the air and that the aerosol spreading of the disease may be the route of infection for barns that never came into contact with outside pigs.
