By farm class, this figure for the total number of swine accessions/diagnostic case submissions breaks down as follows between the weeks of 15 April and 6 October: suckling, 144 (+13); nursery, 111 (+9); grower/finisher, 268 (+11); sows/boars, 132 (+4) and 110 (+8) unknown. The total is up 44 from a week ago.

Kentucky has reported a positive result for the first time in the last week and so the total affected now stands at 18. Those states with 10 or more positive tests are: Iowa, 203; Oklahoma, 174; North Carolina, 117; Kansas, 91; Minnesota, 51; Colorado, 27; Indiana, 26; Ohio, 17 and Pennsylvania, 16.

For the week of 5 to 12 October, North Carolina accounts for the most new positive tests (22 out of the total of 44) but there is no clear development in terms of pig age affected there or in other states.

In mid-June, the reporting system was adjusted. For the weeks prior to 16 June, laboratories were able to provide diagnostic case submissions as wel as 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 6 October, the total number of swine samples testing positive is 2,145, up from 1,919 the previous week (+226). The most-affected states are: North Carolina, 580; Oklahoma, 529; Kansas, 450; Iowa, 192; Minnesota, 139; Colorado, 79; Ohio, 72 and Indiana, 26. Other states, where positive, reported 20 positives or fewer.

In the most recent week reported (week of 6 October), the following states reported one or more positive results: Iowa (12), Kansas (17), Michigan (1), Minnesota (60), Missouri (1), North Carolina (124), Ohio (1), Oklahoma (9) and Pennsylvania (2).

The total number of environmental samples testing positive for PEDv has been reported weekly since the week of 16 June. The total has reached 484, which is 55 more than the previous week's figure. The totals for each state are as follows (with the increase in brackets: Colorado, 14 (=); Iowa, 38 (=); Kansas, 53 (=); Minnesota, 155 (+55); Missouri, 1 (+1); North Carolina, 10 (+2); Ohio, 7 (+1); Oklahoma 157 (=); Pennsylvania, 2 (+1); South Dakota, 1 (=); Virginia, 2 (=); unknown, 49(=).

Note: As a result of the US government shutdown, the National Animal Health Laboratory Network was unable to coordinate the PEDv case information this week. In the interest of maintaining the reporting, the Veterinary Diagnostic Lab at the University of Minnesota agreed to compile the information this week and the diagnostic labs at ISU, KSU and SDSU supported this effort by providing their case accession information to Minnesota for publication. AASV thanks all the labs that pulled together to make this happen.
