Abstract
Virus-containing bioaerosol is an important component of indirect disease transmission in swine-producing regions. The swine industry has begun to implement filtration systems for air entering swine facilities to reduce the risk of airborne spread of virus. It is necessary to know the size and virus distribution of swine bioaerosol to guide filter testing and selection. We present the size and virus distributions of bioaerosol sampled at swine facilities during porcine epidemic diarrhea virus or porcine reproductive and respiratory syndrome virus outbreaks. Variation of the size distribution in rooms housing different weights of swine will be discussed. Particles were sampled in real-time to characterize the size distribution and collected on impactor substrates for offline viral analysis. From these size and virus distributions, two different laboratory surrogate aerosols were developed using live virus and swine fluids relevant to the mode of virus transmission. A characterization of the laboratory surrogate aerosol size and virus distribution will be presented.
