Evaluation of the infectivity of three porcine reproductive and respiratory syndrome virus (PRRSV) variants

23 Jul 2025

Abstract excerpt

Abstract Porcine reproductive and respiratory syndrome virus (PRRSV) continues to burden the US swine industry significantly. In some instances, the virus evaded biosecurity measures, remaining viable in sufficient concentrations to cause an outbreak. Little is known about differences in infectivity among viral variants. In this study, we compared the infectivity of three PRRSV variants by estimating the median...
