Swine Viral Disease Matrix

2018

The Swine Health Information Center, in collaboration with the National Pork Board and the National Pork Producers Council, has developed a prioritized list of endemic and foreign swine pathogens – the Swine Viral Disease Matrix. The complete Matrix includes an assessment of the diagnostic capabilities for selected pathogens based on a review of available literature.

The Swine Viral Disease Matrix originated in an USDA literature review looking for a PEDv pathway into the US. The American Association of Swine Veterinarians reviewed and modified it. Then, in 2015, SHIC took over the responsibility of oversight. It is a living document; a SHIC working group regularly reviews it for content and priority. When a new or emerging disease is identified, there are also ad hoc considerations of content and priority.

The SHIC Monitoring and Analysis Working Group prioritized the list to help focus the SHIC on the US pork industry’s highest risks. The Working Group scored the risk using three criteria, each measured on a 1 (least) to 10 (most) scale.

The Swine Viral Disease Matrix is prioritized based on the average 1-10 score of each pathogen in the three above criteria. The Working Group will continue to review and update the Matrix as new conditions and information emerge.
