Sixteen Additional Deer Test Positive for Chronic Wasting Disease In Hampshire County, West Virginia

Preliminary test results indicate the Chronic Wasting Disease (CWD) agent was present in 16 hunter-harvested deer collected in Hampshire County during the 2009 deer firearms hunting season.

“As part of our agency’s ongoing CWD monitoring effort, samples were collected from 1,091 hunter-harvested deer brought to game checking stations in Hampshire County and one station near the southern Hampshire County line in Hardy County,” noted Frank Jezioro, Director for the W.Va. Division of Natural Resources (WVDNR).

The 16 CWD positive deer included one 4.5 year-old doe, one 2.5 year-old doe, one 1.5 year-old buck, 10 2.5 year-old bucks, and three 3.5 year-old bucks. Thirteen of the latest positive deer were harvested within the Hampshire County CWD Containment Area (i.e., that portion of Hampshire County located North of U.S. Route 50). However, three were located outside the containment area but still within Hampshire County. The area in Hampshire County from which CWD has been detected continues to expand, and the number of infected deer detected this year is 2.5 times more than last year.

CWD has now been detected in a total of 62 deer in Hampshire County (i.e., two road-killed deer, one in 2005 and one in 2008; four deer collected by the WVDNR in 2005; five deer collected by the WVDNR in 2006; one hunter-harvest deer taken during the 2006 deer season; three deer collected by the WVDNR in 2007; six hunter-harvested deer taken during the 2007 deer season; 11 deer collected by the WVDNR in 2008; six hunter-harvested deer taken during the 2008 deer season; eight deer collected by the WVDNR in 2009; and 16 hunter-harvested deer taken during the 2009 deer season).

“The WVDNR will continue to update management actions designed to control the spread of this disease, prevent further introduction of the disease, and possibly eliminate the disease from the state as information from deer testing within West Virginia is gathered and scientists across the country provide more information on how to combat CWD in white-tailed deer,” Jezioro said.

So far, the following disease management actions have been placed into operation by the WVDNR within Hampshire County:

· Implemented CWD testing efforts designed to determine the prevalence and distribution of the disease;

· Established antlerless deer hunting regulations designed to increase hunter opportunity to harvest female deer, adjust deer populations to desired levels and reduce the risk of spreading the disease from deer to deer;

· Established deer carcass transport restrictions designed to lower the risk of moving the disease to other locations;

· Established regulations designed to prohibit the feeding and baiting of deer within the affected area and reduce the risk of spreading the disease from deer to deer.

“Despite our agency’s best efforts, we continue to struggle with CWD in Hampshire County,” said Jezioro. “I am particularly concerned that some individuals are not complying with regulations prohibiting the feeding and baiting of deer within the Hampshire County CWD Containment Area.”

The WVDNR intends to renew its outreach efforts with the public on the critical need for compliance with this regulation. In addition, appropriate enforcement actions will be taken if these problems are not resolved.

“As we strive to meet this wildlife disease challenge and implement appropriate management strategies, the continued support and involvement of landowners and hunters will be essential,” Jezioro said. “The WVDNR remains committed to keeping the public informed and involved in these wildlife disease management actions as we go forward.”

Chronic wasting disease (CWD) is the only known transmissible spongiform encephalopathy affecting free-ranging wildlife. Experimental and epidemiological data indicate that CWD can be transmitted horizontally and via blood and saliva, although the exact mode of natural transmission remains unknown. Substantial evidence suggests that prions can persist in the environment, implicating it as a potential prion reservoir and transmission vehicle. CWD- positive animals can contribute to environmental prion load via biological materials including saliva, blood, urine and feces, shedding several times their body weight in possibly infectious excreta in their lifetime, as well as through decomposing carcasses. Sensitivity limitations of conventional assays hamper evaluation of environmental prion loads in water. Here we show the ability of serial protein misfolding cyclic amplification (sPMCA) to amplify minute amounts of CWD prions in spiked water samples at a 1:1 x106 , and protease-resistant prions in environmental and municipal-processing water samples from a CWD endemic area. Detection of CWD prions correlated with increased total organic carbon in water runoff from melting winter snowpack. These data suggest prolonged persistence and accumulation of prions in the environment that may promote CWD transmission.

The data presented here demonstrate that sPMCA can detect low levels of PrPCWD in the environment, corroborate previous biological and experimental data suggesting long term persistence of prions in the environment2,3 and imply that PrPCWD accumulation over time may contribute to transmission of CWD in areas where it has been endemic for decades. This work demonstrates the utility of sPMCA to evaluate other environmental water sources for PrPCWD, including smaller bodies of water such as vernal pools and wallows, where large numbers of cervids congregate and into which prions from infected animals may be shed and concentrated to infectious levels.

Dear Sir/Madam,

In the Archives of Neurology you quoted (the abstract of which was attached to your email), we did not say CWD in humans will present like variant CJD.

That assumption would be wrong. I encourage you to read the whole article and call me if you have questions or need more clarification (phone: 404-639-3091). Also, we do not claim that "no-one has ever been infected with prion disease from eating venison." Our conclusion stating that we found no strong evidence of CWD transmission to humans in the article you quoted or in any other forum is limited to the patients we investigated.
