Senecavirus A / Seneca Valley Virus (SVA)

Senecavirus A is a vesicular disease in swine that causes symptoms similar to reportable, vesicular diseases, such as Foot and Mouth Disease and Swine Vesicular Disease. Although it is not in itself reportable, because it cannot be visually differentiated from the reportable diseases, it is responded to in a similar manner. Any identification of blisters (vesicles) must be reported to your herd vet.

More information on SVA can be found in the following factsheets:

Porcine Deltacoronavirus (PDCoV)

PDCoV – formerly referred to as “swine deltacoronavirus (SDCv)” – shows very similar clinical signs to PEDv and can be prevented in the same ways. SDCv has been found in the U.S. and Canada. Find out more:

Birds can become infected with an avian deltacoronavirus, which is hard to differentiate structurally from the porcine virus. However, many labs across Canada can now perform analyses to differentiate the two. Numerous environmental samples taken from assembly yards in the Prairies in 2015/16, which were believed to be PDCoV, were later determined to be the avian virus which does not affect pigs.

Porcine Reproductive and Respiratory Syndrome (PRRS)

Porcine reproductive and respiratory syndrome (PRRS) is a production-limiting, viral disease that affects swine herds globally. There are many strains of PRRS, the most devastating being highly pathogenic PRRS.

Certain regions are engaged in Area Regional Control & Elimination (ARC&E) projects, which help pork producers and other sector stakeholders collaborate to control and/or eliminate this disease from a region. Those producers wanting to participate in the Manitoba Coordinated Disease Response (MCDR) initiative can fill out the MCDR Agreement for their farm, which currently covers PED and PRRS, and submit it to This email address is being protected from spambots.

The Canadian Swine Health Board’s PRRS Regional Control & Elimination Playbook outlines some of the measures that can be taken in regions affected by PRRS, depending on the status of the region.

The Ontario Swine Health Advisory Board (OSHAB) has also developed a number of tools and documents to help pork producers in Ontario establish ARC&E projects.

Porcine Circovirus 3 (PCV3)

A new strain of porcine circovirus has been detected in the USA. A factsheet produced by Iowa State University on PCV3 can be found here
