Source: American Association of Swine Veterinarians A seven-year study of large North American sow farms conducted by the University of Minnesota has confirmed that the vast majority of porcine reproductive and respiratory syndrome (PRRS) outbreaks have been due to aerosol spread of the virus. PRRS virus aerosol transmission among herds is a major concern in pig-dense regions and filtration of incoming air, in combination with standard biosecurity procedures, has been demonstrated to prevent transmission of PRRS virus into susceptible herds. read more
