MANITOBA, July 12, 2017 - Reports of porcine epidemic diarrhea virus have exploded in the last two months in Canada.

The government of Manitoba – the province sharing a border with Minnesota and North Dakota – says 51 premises have reported outbreaks of the disease since the beginning of May after just 10 confirmed reports in all of 2014-2016.

The source of the outbreaks has not been determined. The disease has not been detected in the U.S. since an outbreak beginning in 2013 resulted in more than 5,500 cases of the disease across 28 states and the death of millions of pigs. PEDv hits piglets especially hard, potentially killing as much as 100 percent of them at an infected facility. Older animals are still susceptible to the vomiting and diarrhea-induced dehydration brought about by PEDv but generally recover.
