Porcine Epidemic Diarrhea Virus (PEDv)

What's New This Week?

(Last updated: 05/22/2015)



Number of New Cases Reported -- Weekly aggregate update of new cases. USDA Veterinary Services Swine Health Team is now publishing the weekly report which not only includes the weekly accession information you are used to seeing but also additional data derived from the premises information collected as a result of the June 5, 2014 Federal Order. The accession information, as always, reports the number of positive cases tested at the veterinary diagnostic labs that week. The premises data, however, reports the number of positive and presumptive positive cases entered into the USDA's Emergency Management Response Services (EMRS) database. Therefore, the data contained in the accession and premises charts may not represent samples submitted to the diagnostic labs on the same week. Also, this report will only contain data collected since June 5th. USDA maintains all historic data on their SECD website at www.aphis.usda.gov/animal-health/secd. For the week ending 05/16/15, the report indicates there were 81 positive accessions from the 703 submissions (11.5% positive). There are currently 34 states with at least one confirmed positive case of PEDV entered into the USDA database. The report also includes information on cases submitted for porcine deltacoronavirus (PDCoV) as well. Last updated: 5/22/15.


PLEASE NOTE: the chart below now also contains the number of confirmed + presumptive positive premises by week since June 5, 2014.
