Modeling PRRS virus aerosol transmission within and between farms
October 1, 2006By Jeffrey Zimmerman
The objective of this research was to try to understand two major stages of aerosol transmission: 1) how much PRRSV is aerosolized by pigs and 2) how long does airborne PRRSV remain infectious. How...
