Progress made in controlling pig virus

Regional programs prove effective

Scientists and farmers have made progress in controlling and preventing the porcine reproductive and respiratory syndrome (PRRS) virus. According to a panel at the 2010 World Pork Expo, area regional control and elimination programs are among measures that have helped reduce virus transmission.

Swine veterinarians and disease researchers at the expo also said better understanding of air transmission and air filtration developments, with biosecurity and refined herd diagnostic techniques have also helped stop the disease from spreading.

The goal of regional programs is to eliminate the virus on farms in low-prevalence and low-density swine areas, then controlling it in high-prevalence, high-density areas.
