Chronic Wasting Disease (CWD): A chronic wasting disease sample collected by Montana Fish, Wildlife and Parks in late October from a hunter-killed deer was found to be suspect for chronic wasting disease. The sample was collected from a mule deer buck harvested in hunting district 510 south of Billings. The animal was killed in an area with a mixture of private and public land 10 miles southeast of Bridger. A second sample collected from the animal is being sent to the lab at Colorado State University for further testing, with results expected next week. If the result is positive, it will mark the first time CWD has appeared in wild deer, elk or moose in Montana. CWD does not pose a known risk to human health, but the CDC recommends to avoid consumption of animals with CWD.

Norovirus: Two counties (Missoula, Silver Bow) reported norovirus outbreaks at nursing homes this week. All have implemented control measures and worked well with the health department to control spread. For those where specimens have been collected, norovirus was found to be the causative agent. There have been three outbreaks of norovirus reported in recent weeks. The first one involved a restaurant in Yellowstone County.
