SHIC Explores Expansion of National Disease Surveillance Reporting System


The Swine Health Information Center National Disease Surveillance Reporting System was developed as a result of a project to standardize veterinary diagnostic laboratory data using HL7 messaging. SHIC’s support for this work resulted in a model capturing disease dynamics from daily VDL test results by pathogen across time, sample, age group and geographic space. SHIC is currently exploring the potential expansion of the diagnostic database to increase the scope of grower disease diagnostic inputs and regional disease surveillance.

The SDRS providing SHIC’s monthly domestic swine disease surveillance reports is operated at Iowa State University. The goal is to aggregate swine diagnostic data from participating VDL reports and present it in an intuitive format via shared reports and web-based dashboards. SHIC is currently discussing the participation of other state VDLs using USALIMS (Animal Laboratory Information Management System) to seamlessly integrate this information into SDRS. This work could expand the surveillance system to add value to SHIC stakeholders who use the data in their work to protect the health of swine herds.

USALIMS is an off-the-shelf laboratory information management system available for purchase by VDLs. It is fully integrated with its official sister state animal health companion system, USAHERDS, providing automated interstate veterinary permit laboratory test results such as horses negative for equine infectious anemia or streamlining issuance animal movement permits. Seven states currently use both for this purpose. Currently, 18 states use USALIMS to record, report, and bill their veterinary diagnostic laboratory results/information, including animal necropsies submitted to them for diagnostic purposes. USALIMS also provides HL7 messaging for USDA National Animal Health Network laboratories, providing the base architecture needed to extend to include the messaging framework used by SDRS.

Since its inception in 2018, data from four major swine VDLs, Iowa State University, University of Minnesota, South Dakota State and Kansas State, have been compiled for analysis and reporting surveillance of swine pathogens in SHIC’s monthly national disease surveillance report. The Ohio VDL then joined the SDRS. The agents currently monitored are porcine reproductive and respiratory syndrome virus, porcine circovirus 2, porcine epidemic diarrhea virus, swine influenza A virus, porcine deltacoronavirus, transmissible gastroenteritis virus and M. hyopnuemoniae. Pig test results of participating VDLs are organized at the case level by SDRS staff after recovery. Statistical algorithms are then used for global and regional monitoring. An advisory group was formed to help contextualize and interpret the data collected. Reports are then produced and published.

SHIC, launched by the National Pork Board in 2015 solely with funding from Pork Checkoff, continues to focus its efforts on preventing, preparing for, and responding to new and emerging swine diseases to benefit swine health in the United States. SHIC is funded by America’s pork producers to fulfill its mission of protecting and improving the health of America’s hog herd. For more information visit the website or contact Sundberg via E-mail.
