The wild spread of Porcine Epidemic Diarrhea virus (PEDv) appears to be slowing. The American Association of Swine Veterinarians announced 187 positive tests for the disease in the week ending May 17.

While this latest figure brings the total number of confirmed cases to 6,804, the weekly number of cases continues to decline – the lowest since early January. According to Steve Meyer & Len Steiner in Wednesday’s Daily Livestock Report, the peak of confirmed cases was 315 during the week of February 22.

 “Veterinarians have long expected accession numbers to fall this spring as temperatures rise and as the number of naïve herds continues to decline,” Meyer and Steiner said in the report.

Meyer and Steiner also pointed that “pigs farrowed the week of May 10 will not reach market age until mid‐November so we will not see the expected declining impact of these lower accession numbers until this fall. But good news is still good news: Labs are seeing lower numbers of positive submissions.”

Meatingplace adds that there is no firm data on how many hogs have been infection, and each case reported could represent anywhere from a single animal to an entire herd at one site. Some estimate as many as 7 million pigs have been killed in the outbreak, first identified in the United States in April 2013.
