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. SECD is a reportable disease.
Spread of the virus is by the fecal-oral route. Animals must ingest the virus from infected feces. The virus is shed in large numbers in the feces of infected animals. Any object that is contaminated with pig manure (vehicles, people, clothing, shoes, shovels and other animals) can be sources of infection.
Symptoms include acute diarrhea that spreads to pigs of all ages. Vomiting and listlessness may also be exhibited. Because the clinical signs of SECD infections can look like other gastrointestinal diseases that affect pigs, laboratory testing is the only way to confirm SECD.
A Federal Order issued on June 5, 2014 requires that anyone, including producers, veterinarians, laboratory personnel, or others with knowledge of the disease, who identifies a new occurrence of PEDV, PDCoV, or other novel enteric coronavirus must report the occurrence to State and Federal authorities.
