PEDv update: 5,500 cases confirmed across 30 states

According to the National Animal Health Laboratory Network (NAHLN), last week, 257 more cases of Porcine Epidemic Diarrhea (PEDv) were confirmed.

This brings the number of confirmed cases to more than 5,500 since PEDv was identified in U.S. swine herds since April 2013. However, the latest weekly increase is the second lowest reported since mid-January, according to Ron Plain and Scott Brown with the University of Missouri.

NAHLN reports 28 states have confirmed cases of PEDv but suggests this count is actually slightly higher.

“The number of states reported to the NAHLN as having at least one confirmed case of PED now stands at 28. We are aware, however, that cases have also been diagnosed in Vermont and Virginia which would bring the actual state count to 30,” the report said.  

Plain and Brown, like other swine veterinarians across the country, are hopeful new outbreaks will continue to decline as the weather warms.

Purdue University agricultural economist Chris Hurt explained recently that the losses attributed to PEDv was expected to be greatest in the winter, and as the weather turns warmer, these losses will decrease.

"The large losses experienced in February probably mean that losses will continue to be large into March but may lighten as the weather warms into April and the rest of spring," he said.

Early estimates put the nation’s losses of piglets over the last several months to top 5 million, but this figure has since been revised downward with the USDA’s March Hogs and Pigs report.
