By May 2014, it had been identified in 29 of the contiguous states. Incidence has been greatest in the hog dense states and also Oklahoma and Kansas, as shown in Figure 1. Data are number of positives based on sample genetic tests, taken from National Animal Health Laboratory Network (NAHLN), as reported in www.aasv.org/pedv/PEDv_weekly_report_140326.pdf.
