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.
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.
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.
Factsheets on other swine diseases developed by the Center for Food Security & Public Health at Iowa State University can be found here.
