Five Additional Deer Test Positive for Chronic Wasting Disease In Hampshire

County, West Virginia

Preliminary test results have detected the Chronic Wasting

Disease (CWD) agent in five hunter-harvested deer collected in Hampshire

County during the 2007 deer firearms hunting season. “As part of our agency

’s ongoing and intensive CWD surveillance effort, samples were collected

from 1,285 hunter-harvested deer brought to game checking stations in

Hampshire County,” noted Frank Jezioro, Director for the West Virginia

Division of Natural Resources (DNR). The five CWD positive deer included

one 2.5 year-old doe, two 2.5 year-old bucks, one 3.5 year-old buck, and one

4.5 year-old buck. Four of the five deer were harvested within the

Hampshire County CWD Containment Area (i.e., that portion of Hampshire

County located North of U.S. Route 50). The fifth deer was also harvested

in Hampshire County, but it was killed outside the CWD Containment Area near

Yellow Springs, West Virginia.

CWD has now been detected in a total of 19 deer in Hampshire

County (i.e., one road-killed deer confirmed in 2005, four deer collected by

the DNR in 2005, five deer collected by the DNR in 2006, one hunter-harvest

deer taken during the 2006 deer season, three deer collected by the DNR in

2007 and five hunter-harvested deer taken during the 2007 deer season).

Operating within guidelines established by its CWD – Incident Response Plan,

the DNR has taken the steps necessary to implement appropriate management

actions designed to control the spread of this disease, prevent further

introduction of the disease, and possibly eliminate the disease from the


The following disease management actions have been implemented

by the DNR within Hampshire County.

· Continue CWD surveillance efforts designed to determine the

prevalence and distribution of the disease.

· Lower deer population level to reduce the risk of spreading the

disease from deer to deer by implementing appropriate antlerless deer

hunting regulations designed to increase hunter opportunity to harvest

female deer;

· Establish reasonable, responsible and appropriate deer carcass

transport restrictions designed to lower the risk of moving the disease to

other locations;

· Establish reasonable, responsible and appropriate regulations

relating to the feeding and baiting of deer within the affected area to

reduce the risk of spreading of the disease from deer to deer.

“Landowner and hunter cooperation throughout this entire CWD

surveillance effort in Hampshire County has been fantastic,” Jezioro noted.

“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. The DNR remains committed to

keeping the public informed and involved in these wildlife disease

management actions.”

CWD is a neurological disease found in deer and elk, and it

belongs to a family of diseases known as transmissible spongiform

encephalopathies. The disease is thought to be caused by abnormal,

proteinaceous particles called prions that slowly attack the brain of

infected deer and elk, causing the animals to progressively become

emaciated, display abnormal behavior and invariably results in the death of

the infected animal. There is no known treatment for CWD, and it is fatal

for the infected deer or elk. It is important to note that currently there

is no evidence to suggest CWD poses a risk for humans or domestic animals.

“Our well trained and professional wildlife biologists, wildlife

managers and conservation officers are working diligently to fully implement

the DNR’s CWD – Incident Response Plan, which is designed to effectively

address this wildlife disease threat,” said Jezioro. “Hunters, landowners

and other members of the public should feel confident that we have some of

the best wildlife biologists and veterinarians in the world, including those

stationed at the Southeastern Cooperative Wildlife Disease Study in Athens,

Georgia, working collaboratively on this situation.”

14. Preliminary research findings suggest that the potential risk of

transmission of vCJD via dental procedures may be greater than previously

anticipated. Although this research is incomplete, uses an animal model

exposed to relatively high doses of infectivity, and there are no data from

infectivity studies on human oral tissues, these findings suggest an

increased possibility that vCJD may be relatively efficiently transmitted

via a range of dental procedures. Ongoing infectivity studies using human

oral tissues and the other studies suggested here will enable more precise

assessment of the risks of vCJD transmission through dental procedures.

-- Cases are listed based on the year of death when available. If the

year of death is not available, the year of sample receipt is used.

-- Referrals: Cases with possible or probable prion disease from

which brain tissue or blood in the case of familial disease were submitted.

-- Inconclusive: Cases in which the samples were not sufficient to

make a diagnosis.

-- Non-vCJD type unknown are cases in which the tissue submitted was

adequate to establish the presence but not the type; in all cases,

vCJD could be excluded.

[In submitting these data, Terry S. Singeltary Sr. draws attention to

the steady increase in the "type unknown" category, which, according

to their definition, comprises cases in which vCJD could be excluded.

The total of 26 cases for the current year (2007) is disturbing,

possibly symptomatic of the circulation of novel agents.

Characterization of these agents should be given a high priority. - Mod.CP]

There is a growing number of human CJD cases, and they were presented last

week in San Francisco by Luigi Gambatti(?) from his CJD surveillance


He estimates that it may be up to 14 or 15 persons which display selectively

SPRPSC and practically no detected RPRPSC proteins.
