PED-Positive Submissions: Increase Slows?

19 September 2013

US - The total number of swine accessions and diagnostic case submissions testing positive for the Porcine Epidemic Diarrhoea (PED) virus is now 612, according the latest figures from the American Association of Swine Veterinarians (AASV) dated 18 September.

By farm class, this figure breaks down as follows since the week of 15 April: suckling, 106; nursery, 82; grower/finisher, 226; sows/boars, 112 and 81 unknown. The total is up 28 from a week ago.

Once again, no new states reported a positive result in the last week and so the total affected remains at 17. Those states with 10 or more positive tests are: Iowa, 181; Oklahoma, 155; Kansas, 77; Minnesota, 43; North Carolina, 40; Indiana and Colorado, both 24, Ohio, 16 and Pennylvania, 12. Of these states, Oklahoma reported the highest number of new cases at 13.

In mid-June, the reporting system was adjusted. For the weeks prior to 16 June, laboratories were able to provide diagnostic case submissions and the number of premises testing positive for PEDv. Since 16 June, the data refer only to diagnostic cases submissions ('swine accessions').

From the week of 16 June to week of 8 September, the total number of swine accessions testing positive is 1,451, up from 1,385 the previous week (+66). The most-affected states are: Oklahoma, 468; Kansas, 390; North Carolina, 191; Iowa, 152; Colorado, 73; Ohio, 58; Minnesota, 51 and Indiana, 25. Other states, where positive, reported 20 positives or fewer.

In the most recent week reported (week of 8 September), the following states reported one or more positive results: Kansas (25), North Carolina (11), Ohio (3), Oklahoma (26) and Tennessee (1).
