Porcine respiratory coronavirus (PRCoV) is a natural mutant of Transmissible gastroenteritis virus (TGEV) and was first identified in Belgium in 1984. PRCoV has been identified in Europe, USA, Canada, Croatia, Japan, and Korea. Current prevalence of PRCoV is unknown. PRCoV spreads readily via aerosol and direct contact between pigs, but symptoms of disease are mild, making detection difficult. The primary consequence of PDCoV is its potential to confound diagnosis of TGEV, a much more severe disease.
Notice: PRCoV shares the same species name as TGEV and has high genetic similarity. However, there are few to no commonalities in epidemiology, pathogenesis, and clinical signs. TGEV and PRCoV will be differentiated whenever possible, but in the event classification is uncertain, the sample will be labeled as TGEV by default.
