USDA reports swine coronavirus outbreaks to OIE

On April 21 Dr. John Clifford, from USDA APHIS, submitted information about 29 outbreaks of Novel Swine Enteric Coronavirus disease (SECoV) to OIE that affected 5978 pigs in 29 states.

The 29 states were Ohio, Indiana, Iowa, Colorado, Minnesota, Pennsylvania, Missouri, Oklahoma, South Dakota, Illinois, Michigan, Kansas, New York, North Carolina, Tennessee, Texas, Wisconsin, Kentucky, Maryland, Nebraska, California, Wyoming, South Carolina, Arizona, Idaho, Montana, North Dakota, Vermont, and Mississippi.

The source of the outbreaks is unknown.

According to the OIE, SECoV is a disease in swine caused by emerging porcine coronaviruses, including Porcine Epidemic Diarrhoea Virus (PEDV) and Porcine Delta Coronavirus (PDCoV).

SECoV affects swine causing diarrhoea, vomiting, and 50% to 100% mortality of infected piglets. The clinical presentation of SECoV infections in growing pigs can be variable in its severity and not readily distinguishable from many other causes of diarrhoea in growing pigs. While adult pigs can become infected, mortality is low. SECoV is clinically indistinguishable from Transmissible Gastroenteritis (TGE), another swine disease caused by a coronavirus that is endemic in the United States.
