More Than 200 US Pig Farm Samples Positive for Porcine Delta Corona Virus

26 May 2014

US - Porcine Delta Corona virus (PDCoV) has been detected in 207 samples from pig farms in 14 states.

For the latest weekly report - for the week of 17 May in a report dated 21 May from the USDA Animal Health Inspection Service and made available by the American Association of Swine Veterinarians (AASV) - 22 pig farms (termed "swine accessions") have tested positive for the PDCoV, bringing the cumulative total to 207.

The National Animal Health Laboratory Network (NAHLN) began collating testing data on PDCoV for the week of 30 March 2014. So far, 1,546 accessions have been tested, 215 in the most recent week reported, so the overall percentage found positive is 13 per cent.

No new states have reported one of more positive accessions in the latest week and so the total remains at 14 (Table 1 and Figure 1).

PDCoV was previously known as Swine Delta Corona virus (SDCv). It is related and causes similar effects to the virus that causes Porcine Epidemic Diarrhoea (PED).
