Porcine reproductive and respiratory syndrome virus (PRRSV) control has been challenging and frustrating for researchers, veterinarians and producers in the swine industry worldwide since the first discovery of the disease in 1989. The aim of PRRSV control is to reach stability among the breeding females, thereby producing non-infected offspring from a previously infected sow population. The target animals for PRRSV control are the breeding and growing pig population. The procedure for achieving PRRSV control for a breeding herd includes stabilization (mass exposure or mass vaccination), herd closure, introduction of exposed non-shedding replacement gilts (isolation and acclimation) and monitoring stabilization. The procedure for growing pigs includes vaccination and nursery depopulation. The common procedures of PRRSV control include biosecurity and a surveillance programme. This review paper describes several options for each procedure that could be implemented practically in commercial herds.
