CWD case in Shawano County signals spread in northeastern Wisconsin

Shawano County, Wisconsin, had its first confirmed case of chronic wasting disease (CWD) in wild deer, according to a WBAY news story yesterday. CWD is a fatal, prion-caused neurologic disease affecting the deer family.

The deer was hunter-harvested during the gun season in the town of Germania, indicating CWD has spread farther in northeastern Wisconsin. This new case could affect baiting and feeding regulations within a 10-mile radius, which includes Waupaca (0 prior cases), Portage (8), and Marathon (1) counties.

"It's unfortunate, but not a big surprise to have found it near there," Department of Natural Resources (DNR) district wildlife biologist Jeff Pritzl told WBAY. "But we do want to get a better handle now on figuring out where is the edge of the spread of the disease and infection rate and that type of thing, so we will be working with landowners in that area, the hunting public to further intensify our surveillance in that immediate area."

The CWD data available on the state's DNR site goes only through 2020 and does not list the new case. Thus far, the agency has not released a public report on the Shawano County finding.

Iran, South Korea report more H5N8 avian flu outbreaks in poultry

Iran today became the latest country to report highly pathogenic H5N8 avian flu in poultry this winter, with already affected countries in Asia and Europe reporting more detections in poultry and wild birds, according to the latest notifications from the World Organization for Animal Health (OIE).

Iran's outbreak began Dec 28 at a layer farm in South Khorasan province in the eastern part of the country, which killed 1,008 of 255,000 susceptible chickens. The event marks the first appearance of the virus in the country's poultry in nearly a year.

Elsewhere, South Korea reported nine more H5N8 outbreaks in poultry from six provinces plus the city of Sejong. The outbreaks started from Dec 28 to Jan 9, affecting commercial layer farms and duck farms. Taken together, the virus killed 648 of 666,700 birds. In a separate report, the country also confirmed 11 more H5N8 detections in wild birds, including 3 in Seoul.

In Europe, Russia noted another detection of H5N8 in wild birds.
