Emergence of a virulent porcine reproductive and respiratory syndrome virus in Taiwan in 2018

Abstract

Summary In March 2018, an abortion storm caused by porcine reproductive and respiratory syndrome virus was confirmed in a farrow‐to‐finish pig herd in Taiwan. Open reading frame 5 and non‐structural protein 2 of the virus confirmed that the virus is closely related to the virulent strains circulating in the United States.
