A viral disease of domestic pigs, first recognized in the United States and Germany in the late 1980s, that causes late-term reproductive failure in sows, including stillbirths and weak piglets, along with respiratory disease in pigs of all ages. It spread to nearly every major pig-producing country within a decade of its discovery and is considered the costliest disease of the global swine industry, driven in large part by the virus's unusually high mutation rate, which continually produces new strains that evade existing vaccines.
