July Domestic Swine Disease Monitoring Report Now Available

The Swine Health Information Center's (SHIC) July Domestic Swine Disease Monitoring Report is available. In the July Domestic Swine Disease Monitoring Report, we learn porcine reproductive and respiratory (PRRS) virus cases dropped in June compared to May. Overall detection of PRRSV-positive cases was in the upper boundaries of the forecasted levels for the first three weeks of June. The overall percentage of porcine epidemic diarrhea virus (PEDV) RNA-positive cases in June also decreased compared to May and were within expected boundaries of forecasted levels for this time of year. Porcine delta coronoavirus (PDCoV) cases were just slightly lower in June compared to May and there was one positive case of TGEV RNA in June 2020. Mycoplasma hyopneumoniae-positive cases in June were within the forecasted levels for this time of year.

What is the Swine Disease Reporting System (SDRS)?

SHIC-funded, veterinary diagnostic laboratories (VDLs) collaborative project, with goal to aggregate swine diagnostic data from participating reporting VDLs, and report in an intuitive format (web dashboards), describing dynamics of disease detection by pathogen or disease syndrome over time, specimen, age group, and geographical space. For this report, data is from the Iowa State University VDL and South Dakota State University ADRDL. University of Minnesota VDL and Kansas State University VDL. Specifically, for PRRSV RFLP data, and syndromic information the results are from Iowa State University VDL. For all "2019 predictive graphs," the expected value was calculated using a statistical model that considers the results from three previous years. The intent of the model is not to compare the recent data (2019) to individual weeks of previous years. The intent is to estimate expected levels of percent positive cases based on patterns observed in the past data, and define if observed percentage positive values are above or below the expected based on historic trends.
