Swine Enteric Coronavirus Diseases (SECD), including Porcine Epidemic Diarrhea virus (PEDv)


Since its appearance in the United States in April 2013, PEDv has spread within the swine industry. In early 2014, an additional related virus, porcine delta coronavirus (PDCoV), appeared in this country. Infections with these novel SECD can cause significant morbidity and mortality, particularly in young piglets.

Federal Order and Reporting Information

In response to a large number of SECD cases that were causing significant hardship for the U.S. swine industry, APHIS issued a Federal Order in June 2014 making SECD a reportable disease. At the same time, USDA made funds available to cover specific costs associated with the disease. On January 4, 2016, the United States Department of Agriculture’s (USDA) Animal and Plant Health Inspection Service (APHIS) issued a revised Federal Order to more effectively use remaining emergency funding.  SECD remains a reportable disease, which means that producers, veterinarians, and diagnostic laboratories are required to report all cases of SECD to USDA or State animal health officials. The reporting criteria are unchanged in the revised Federal Order.
The revised Federal Order eliminates the herd plan requirement, as well as reimbursement to veterinarians for completing those plans. It also eliminates reimbursement for biosecurity actions, like truck washing.
USDA and the States are collaborating with herd veterinarians and producers to manage the diseases in a manner that supports business continuity for commercial pork producers and maintains a plentiful supply of pork for consumers.
