The World Animal Health Organization (OIE) issued April 21 an "alert" on the emerging novel swine enteric corona virus (SECoV) in the U.S. since April 2013, based on information submitted by the U.S. Department of Agriculture's Animal & Plant Health Inspection Service (APHIS).
In the report, APHIS deputy administrator Dr. John Clifford explained that SECoV is a disease in swine caused by emerging porcine coronaviruses, including porcine epidemic diarrhea virus (PEDV) and porcine delta coronavirus (PDCoV). SECoV affects swine causing diarrhea, vomiting and 50-100% 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 diarrhea in growing pigs. While adult pigs can become infected, mortality is low. SECoV is clinically indistinguishable from transmissible gastroenteritis, another swine disease caused by a coronavirus that is endemic in the U.S., the report said.
Since SECoV/PEDV are not OIE-reportable diseases, the voluntary report was issued due to the "emerging" status of the outbreak.
The report notes 5,978 cases in 29 states as of April 16: Missouri, Ohio, Kansas, Maryland, South Carolina, Tennessee, Vermont, Kentucky, South Dakota, Texas, Illinois, Indiana, Wisconsin, Colorado, Iowa, Montana, Nebraska, Idaho, Michigan, Pennsylvania, Wyoming, Arizona, California, North Carolina, North Dakota, Minnesota, Mississippi, New York and Oklahoma. Other data on the number of swine deaths and number of susceptible animals were noted as "not calculated because of missing information."
