Technical Abstract: Porcine reproductive and respiratory syndrome (PRRS) has been a major economic problem for the United States swine industry since its first clinical recognition more than a decade ago. It is now widespread, and there is a question of whether the tools currently being used for its prevention and control will appreciably reduce its prevalence. Although vaccines for PRRS are used extensively in the United States, they seem to be generally less effective than many of those used for other virus-induced diseases of veterinary importance. Moreover, there is some concern about the safety of attenuated PRRS vaccines. Nevertheless, a great deal has been learned about PRRS and PRRS virus during about the last 10 years, and although the battle against PRRS has yet to be won, there is reason for hope. The discussion in this manuscript focuses on some of what is known about PRRS today, especially in regard to its epidemiology and control in North America.
