Improved measures for prevention and treatment have helped slow the spread of porcine epidemic diarrhea, but the virus remains a significant threat, a Purdue University swine specialist said.
Allan Schinckel, professor of animal sciences, said any hog exposed to PEDv could trigger another outbreak.
"It is critical that producers and veterinary care practitioners remain vigilant," Schinckel said. "Still, we are in better shape than last year."
PEDV causes intestinal disease in swine of all ages but has an especially high mortality rate among pre-weaned piglets. In 2014, PEDv was blamed for the deaths of millions of baby pigs, reducing hog production by about 7 percent and driving up pork prices.
Fewer deaths have been reported in 2015, due in part to increased biosecurity including the increased use of disinfectants in trailers, pens and other places where hogs are transported and regrouped, Schinckel said.
In addition, new vaccines have been licensed for use.
"That has been especially important for the long term because vaccines can reduce the severity of the disease if the disease has a second wave in the next two years," Schinckel said.
To help producers, veterinarians, students and faculty stay informed on the latest developments, Purdue's Pork Interest Group will host a PEDv meeting April 13. The meeting will also be presented as a live webinar.
