Game and Fish finds CWD in new deer hunt area near Osage
The Wyoming Game and Fish Department confirmed chronic wasting disease (CWD) in a doe mule deer in hunt area 7.

Cheyenne - The Wyoming Game and Fish Department confirmed chronic wasting disease (CWD) in a doe mule deer. The deer was harvested by a hunter in deer hunt area 7 about three miles west of Osage on October 1. CWD is a fatal neurological disease of deer, elk and moose. This is the first time CWD has been found in deer in hunt area 7, which is bordered by endemic deer areas 8, 6 and 9.
Consistent with the Centers for Disease Control, Game and Fish does not recommend people eat deer, elk or moose that test positive for CWD. The Wyoming Game and Fish Department is reminding hunters that they play a significant role in monitoring the further spread of this disease and providing valuable information for managing CWD.
As many deer and elk seasons open on October 15th, hunters are reminded they have many options to submit a sample for testing:
- Game and Fish check stations - these are established throughout the state during big game seasons.
- In the field - when in contact with a game warden, wildlife biologist, or other employee who are collecting CWD samples.
- Wyoming State Veterinary Lab - Hunters wishing to have their animal tested outside the Department’s monitoring program may contact the Wyoming State Veterinary Lab in Laramie for details and cost. The telephone number is (307) 766‐9925.
- Select meat processors and taxidermists - in certain locations during opening day or few days after seasons open a Game and Fish employee is present at some of these businesses. Availability varies greatly across the state.
- Game and Fish regional offices - in many cases if a hunter stops at a Game and Fish office to get a CWD sample collected, the hunter will have to leave the head at the office until such time a warden or biologist is available to take the sample as they are in the field a majority of the hunting season. But, stop by to check or call first to see what arrangements can be made.
Game and Fish personnel also continue to watch and sample for CWD from deer, elk and moose that appear sick. If you see a deer, elk or moose that appears to be sick or not acting in a normal manner, please contact your local game warden, wildlife biologist or Game and Fish office immediately. Game and Fish personnel collect and analyze more than 1,600 CWD samples annually throughout the state.
Please visit the Game and Fish website for more information on chronic wasting disease transmission and regulations on transportation and disposal of carcasses.

Interpretive Summary: Chronic wasting disease (CWD) is a fatal neurodegenerative disease that occurs in farmed and wild cervids (deer and elk) of North America and was recently diagnosed in a single free-ranging reindeer (Rangifer tarandus tarandus) in Norway. CWD is a transmissible spongiform encephalopathy (TSE) that is caused by infectious proteins called prions that are resistant to various methods of decontamination and environmental degradation. Little is known about the susceptibility of or potential for transmission amongst reindeer. In this experiment, we tested the susceptibility of reindeer to CWD from various sources (elk, mule deer, or white-tailed deer) after intracranial inoculation and tested the potential for infected reindeer to transmit to non-inoculated animals by co-housing or housing in adjacent pens. Reindeer were susceptible to CWD from elk, mule deer, or white-tailed deer sources after experimental inoculation. Most importantly, non-inoculated reindeer that were co-housed with infected reindeer or housed in pens adjacent to infected reindeer but without the potential for nose-to-nose contact also developed evidence of CWD infection. This is a major new finding that may have a great impact on the recently diagnosed case of CWD in the only remaining free-ranging reindeer population in Europe as our findings imply that horizontal transmission to other reindeer within that herd has already occurred. Further, this information will help regulatory and wildlife officials developing plans to reduce or eliminate CWD and cervid farmers that want to ensure that their herd remains CWD-free, but were previously unsure of the potential for reindeer to transmit CWD.
Technical Abstract: Chronic wasting disease (CWD) is a naturally-occurring, fatal prion disease of cervids. Reindeer (Rangifer tarandus tarandus) are susceptible to CWD following oral challenge, and CWD was recently reported in a free-ranging reindeer of Norway. Potential contact between CWD-affected cervids and Rangifer species that are free-ranging or co-housed on farms presents a potential risk of CWD transmission. The aims of this study were to 1) investigate the transmission of CWD from white-tailed deer (Odocoileus virginianus; CWDwtd), mule deer (Odocoileus hemionus; CWDmd), or elk (Cervus elaphus nelsoni; CWDelk) to reindeer via the intracranial route, and 2) to assess for direct and indirect horizontal transmission to non-inoculated sentinels. Three groups of 5 reindeer fawns were challenged intracranially with CWDwtd, CWDmd, or CWDelk. Two years after challenge of inoculated reindeer, non-inoculated negative control reindeer were introduced into the same pen as the CWDwtd inoculated reindeer (direct contact; n=4) or into a pen adjacent to the CWDmd inoculated reindeer (indirect contact; n=2). Experimentally inoculated reindeer were allowed to develop clinical disease. At death/euthanasia a complete necropsy examination was performed, including immunohistochemical testing of tissues for disease-associated CWD prion protein (PrPcwd). Intracranially challenged reindeer developed clinical disease from 21 months post-inoculation (months PI). PrPcwd was detected in 5 out of 6 sentinel reindeer although only 2 out of 6 developed clinical disease during the study period (< 57 months PI). We have shown that reindeer are susceptible to CWD from various cervid sources and can transmit CWD to naïve reindeer both directly and indirectly.
