Porcine reproductive and respiratory syndrome virus (PRRSV) has been reported to be the most costly pathogen causing reproductive disease and decreased growth performance. The virus continues to evolve and considerable variability exists among isolates in virulence, apparent protection from vaccination and our time required to eliminate the virus from sow herds. Lacking any data on prevalence or incidence in the industry, we started a Swine Health Monitoring Program in 2012 (Tousignant et al).
