SHIC Initiated Swine Disease Reporting System Continues to Expand with PCV2
May 4, 2022 — Paul Sundberg
The Domestic Swine Disease Reporting System, funded by the Swine Health Information Center, collects and disseminates information on endemic and emerging diseases affecting the US swine herd. Following the addition of influenza A virus in swine in April 2022, porcine circovirus type 2 information will be included starting in May 2022, in response to stakeholder requests. Monitoring these two viruses known for different clinical manifestations adds value to SDRS reports while providing needed information for producers and veterinarians.
Tracking IAV-S and PCV2, along with porcine reproductive and respiratory syndrome virus and Mycoplasma hyopneumoniae, the SDRS now monitors the whole suite of porcine respiratory disease complex. Historical PCV2 data has been fully incorporated and a new page will be included in SDRS report #51. Monthly updates about PCV2 DNA detection will now be a regular component of SDRS reports and dashboards are also available on the SDRS webpage under the PCV2 detection dashboard.
SDRS, a collaborative project with data from Iowa State University, University of Minnesota, South Dakota State University, Kansas State University, and Ohio Animal Disease Diagnostic Lab, is currently the only publicly available source of swine health information from veterinary diagnostic labs. SDRS reports contain information aggregated from these participating VDLs, providing data to assist veterinarians and producers in making informed decisions on disease prevention, detection, and management. In addition to the porcine respiratory disease complex, SDRS also reports porcine epidemic diarrhea virus, porcine deltacoronavirus, and transmissible gastroenteritis virus, the three agents classified as porcine enteric coronaviruses.
After aggregating then summarizing the data and information for the viruses and bacterial agents or diseases being monitored, the input of an SDRS advisory group, which consists of veterinarians and producers across the US swine industry, is included. The intent is to provide farm-level context to the observed data and to summarize the implications to the industry. The advisory group identified PCV2, one of the major respiratory pathogens affecting the swine industry, as a gap in reporting due to its role as an element of the porcine respiratory disease complex.
SDRS reports are the result of a VDL data standardization project SHIC supported. The SDRS model describes dynamics of disease detection by pathogen over time, specimen, age group, farm type, and geographical space. The report provides benchmark comparison data, providing tools for detecting trends, regionalization, and understanding how to react to outbreaks. The SDRS is the only source of information on active pathogens in all phases of production including boar studs and the breeding and grow-finish segments. The SDRS team welcomes input for the report, which keeps evolving based on input from the industry and the advisory group since it was initiated in 2017.
SDRS reports are published in the monthly SHIC newsletter (subscribe here) and on the first Tuesday of each month on the SDRS website and sent to those who subscribe to the reports (send subscription request to sdrs@iastate.edu). The website dashboard is updated daily, a real-time data source.
SHIC, launched by the National Pork Board in 2015 solely with Pork Checkoff funding, continues to focus efforts on prevention, preparedness, and response to novel and emerging swine disease for the benefit of US swine health. As a conduit of information and research, SHIC encourages sharing of its publications and research. Forward, reprint, and quote SHIC material freely. SHIC is funded by America's pork producers to fulfill its mission to protect and enhance the health of the US swine herd.
