By farm class, this figure breaks down as follows since the week of 15 April: suckling, 75; nursery, 58; grower/finisher, 216; sows/boars, 98 and 72 unknown. The total is up 30 from a week ago.

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, 173; Oklahoma, 128; Kansas, 59; Minnesota, 40; North Carolina, 26; Colorado and Indiana, 22 and Ohio, 14. Of these states, Oklahoma reported the highest number of new cases at 14.

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').

Since the week of 16 June, the total number of swine accessions testing positive is 1,229, up from 1,157 the previous week (+72). The most-affected states are: Oklahoma, 414; Kansas, 331; North Carolina, 147; Iowa, 141; Ohio, 53; Minnesota and Colorado, both 47 and Indiana, 22. Other states, where positive, reported 20 positives or fewer.
