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 the significant impact novel SECD, including PEDv and PDCoV, are having on the U.S. pork industry, USDA issued a Federal Order on June 5, 2014. There are two basic requirements of the Federal Order:

  1. Producers, veterinarians, and diagnostic laboratories are required to report all cases of novel SECD to USDA or State animal health officials.
  2. Herds/premises confirmed to be affected with these viruses must work with a veterinarian – either their herd veterinarian, or USDA or State animal health officials – to develop and implement a reasonable herd/premises management plan to address the detected virus and prevent its spread.

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.

Herd Management Plans

If you have an SECD-positive herd, you will need to complete a herd/premises management plan.  To learn more about SECD herd management plans, read the SECD Herd/Management Plan Requirements.
