Illinois Chronic Wasting Disease: 2012-2013 Surveillance and Management
Report Paul Shelton and Patrick McDonald Forest Wildlife Program, Illinois
Department of Natural Resources August 30, 2013
Background
First CWD positive: A suspect adult female deer from northwest Boone County
was diagnosed with CWD in November 2002, after exhibiting clinical signs that
included food impaction, aspiration pneumonia, and behavioral
abnormalities.
Total samples through June 30, 2012: 66,045+
Total positives through June 30, 2012: 372
Number of counties affected through June 30, 2012:
10 (JoDaviess, Stephenson, Winnebago, Boone, McHenry, Ogle, DeKalb, Kane,
LaSalle, Grundy)
Distribution through June 30, 2012:
90% of positives were found in the four original CWD counties (Winnebago,
Boone, McHenry, and DeKalb), while 2 of those counties (Winnebago and Boone)
accounted for 71% of positives. The outbreak consisted of a central core of
disease along the Winnebago‐Boone county line, with more diffuse distribution at
increasing distance from that area (Fig. 1).

CWD Surveillance Protocols During FY2012‐2013 (July 1, 2012‐June 30,
2013)
Testing: All CWD testing was conducted using immunohistochemistry (IHC) at
Illinois Department of Agriculture’s (IDOA) Animal Disease Laboratory in
Galesburg, Illinois. Samples were initially screened using retropharyngeal lymph
nodes (RPLN), followed by confirmatory testing of recut RPLN tissue and
obex.
Sampling of hunter‐harvested deer: Three sources were used to provide
tissue samples from adult deer harvested by hunters: (1) mandatory firearm deer
check stations in high‐risk counties in northern Illinois; (2) designated
voluntary drop‐off testing locations in northern Illinois; and (3) cooperating
meat lockers/taxidermists who collected heads/sample tissues for IDNR.
Surveillance by other agencies/individuals authorized by special permits:
Recipients of special permits from IDNR authorizing lethal deer removals were
required to collect CWD samples when working in high‐risk CWD areas or in areas
needing additional surveillance. These permits included (1) Deer Population
Control Permits (used by some agencies to control urban deer populations); (2)
nuisance Deer Removal Permits (for crop depredation, etc.); and (3) Scientific
Permits (various research projects).
Suspect (“target”) deer surveillance: Upon receiving reports from the
public about sick deer, IDNR staff collected samples for CWD testing from deer
that exhibited signs/symptoms consistent with chronic wasting disease.
Surveillance from post‐hunting season sharpshooting: Sharpshooting was conducted
from mid‐January through the end of March by trained IDNR staff. Sharpshooting
was restricted to areas where CWD‐infected deer had been identified (limited to
lands within a 2‐section buffer around known positive sections).
CWD Surveillance Results FY2012‐2013
Total number of CWD samples collected statewide: 8,069. Figure 3 compares
our yearly collection efforts; Appendix A summarizes the samples
collected/positives identified by county and collection source.
Number of usable samples collected: 8,064
Number of CWD‐positive deer identified: 36. Table 1 presents a comparison
of the number of positive deer found each year by county.
Number of counties with positive deer: 12 — Boone (4), DeKalb (7), DuPage
(1), Grundy (3), JoDaviess (1), Kane (4), Kendall (1), LaSalle (1), McHenry (3),
Ogle (3), Stephenson (3), Winnebago (5). For distribution of positive sections,
see Figure 5.
Number of new CWD counties: 2 — DuPage and Kendall
CWD prevalence information for the 12‐county CWD area (adult deer from
hunting sources only) —
Average CWD prevalence (all adult deer): 0.54% (20/3702)
Average CWD prevalence (adult males): 0.52% (10/1919)
Average CWD prevalence (adult females): 0.56% (10/1783)

Discussion: Illinois CWD in FY2012‐2013 Thirty‐six CWD‐positive deer were
identified from 8,064 usable samples collected statewide. Estimated prevalence
rates in the CWD counties remained low, with an overall rate of 0.54% in the
12‐county area. There has been no increasing trend in CWD prevalence since 2002
(Fig. 8), in contrast with increasing prevalence trends observed in many other
states where chronic wasting disease has been found. Estimated prevalence rates
in the original four CWD counties have averaged about 2.5 times higher than in
the 12‐county area during this period. There are some specific local areas of
concern in Illinois. These include (1) areas in which there is resistance to
management (and therefore limited sharpshooting), which has created refuges for
sick animals; and (2) recently‐established, outlying disease foci with
increasing prevalence rates, in which our initial management approach has
typically been limited to a small amount of sharpshooting for follow‐up
surveillance after discovery of CWD in the area.
Surveillance resulted in identification of positive deer in two new
counties this year: a suspect adult female deer near Yorkville in Kendall County
in July 2012; and an adult female taken under authority of a Deer Population
Control Permit in DuPage County in November 2012.
snip...
For the second straight year, highest CWD prevalence rates in adult deer
(12.77%) were found in Block 2,0, which includes the northwest corner of DeKalb
County (Fig. 6). There is opposition to disease management in this area, and the
Department has access to only a few properties for sharpshooting, so conditions
are unlikely to improve unless additional cooperators can be found. High
prevalence was also observed in Block 3,4 (Northeast DuPage County — a new
area), but those high rates were due to sample distribution in relation to the
block boundaries. After initial detection of the positive deer, additional
samples were collected locally for follow‐up evaluation, but the boundary of the
block is within a few hundred yards of the positive location, and most follow‐up
samples fell into Block 3,3. However, no additional positive deer were found,
and most suitable deer habitat in that area falls to the west in Block 3,3.
During winter 2012‐13, sharpshooting activities were confined to peripheral
areas outside the main disease core, and aimed at preventing disease spread.
Many of the sharpshooting locations were ‘spark’ areas, where CWD has been found
but is not known to be established. In those locations the primary goal was to
gather additional surveillance information to clarify the disease status of the
area, rather than to bring about significant population change. Because of this,
the number of deer taken at those locations was limited, and sharpshooting
ceased when surveillance quotas were reached. Higher numbers of deer were taken
from areas which have produced multiple CWD cases, particularly where deer
densities are high. Agency sharpshooters removed 661 deer, with an additional
229 removed by permittees with Deer Population Control Permits.
snip...
In 2013 scientists from the Illinois Natural History Survey, the University
of Illinois, Purdue University, and the Department of Natural Resources
published the results of a study that examined the effectiveness of the first
several years of IDNR’s management program for chronic wasting disease in the
northern Illinois deer herd. The paper appears in the Journal of Preventive
Veterinary Medicine (Vol. 110: 541‐548), and is available online (without
charge) at
http://www.sciencedirect.com/science/journal/01675877.
The authors concluded that IDNR sharpshooting was associated with a decline
in CWD prevalence in the areas where management occurred during the study
period. Some other findings of the study included:
• In areas with management, declines in CWD prevalence were more
consistently observed in young deer than in adults, suggesting that management
reduced the risk of new infections;
• In areas where no sharpshooting occurred, the odds of a female deer
having CWD were about 2.5 times higher than in areas where sharpshooters removed
moderate to high numbers of deer (9‐59 deer per section per year). Results for
male deer differed somewhat, with lower risk of CWD at different levels of
sharpshooting. Additional years of data should help clarify the nature of this
relationship;
• Deer taken by agency sharpshooters were about twice as likely to be
CWD‐positive than deer taken by hunters.
The results suggest that frequent and consistent sharpshooting events with
at least moderate culling intensity are needed to reduce CWD prevalence.

CWD Testing Exception for HD Events
1
Overview
A requirement of the federal CWD interim final rule is that every
qualifying cervid twelve months of age and older that originates from a herd
participating in the CWD Herd Certification Program be sampled and tested for
CWD at the time of death. In addition, herd owners enrolled in the program are
required to report these deaths to the office of the State Animal Health
Official (SAHO).
An exception to this requirement can be made by the SAHO in the case of a
mass casualty / mortality event such as Hemorrhagic Disease (HD) caused by
(Epizootic Hemorrhagic Disease Virus (EHDV) or bluetongue virus (BTV). In these
events, CWD sample collection can be limited to two (2) animals per event. When
only two animals are to be sampled, the sample collector will sample the highest
risk animals available for testing. This includes older animals, males
preferentially over females, and those animals having any known pre-existing
health conditions. In addition to the above, since one cannot predict which
animals may die during a HD event, all males 4 years of age and older that die
during the event must have samples submitted for testing. All animals 12 month
or older that die and are in poor body condition must be sampled regardless of
the ongoing HD event. All deaths must continue to be reported even if an HD
event is ongoing.
Definitions
HD Event: A HD event is considered to be ongoing when there is acute, mass
morbidity / mortality occurring in a herd during the time of year when biting
midges are active and a diagnosis of HD has been made in the herd by the herd
veterinarian. The event will be considered to be over 10 days after the first
killing frost has occurred since the diagnosis was made.
Diagnosis: A veterinary diagnosis of HD will be considered to be valid if
it meets one of the following criteria:
1. The veterinarian has submitted blood samples from one or more animals in
the herd and the testing laboratory has confirmed HD infection.
2. The veterinarian or herd owner has submitted one or more animals to a
veterinary diagnostic laboratory and the laboratory has made the HD
diagnosis.
3. The veterinarian has submitted tissues from a field necropsy to a
veterinary diagnostic laboratory and the laboratory has made the HD
diagnosis.

Greetings Illinois Officials and Hunters et al,
amazing, a perfectly good time to test a mass kill event for cwd i.e.
during a supposedly ehd outbreak, where 100s of deer are dead at once, a perfect
time for cwd testing to find out the real numbers on cwd, and what do they do,
regulations call to test only 2 animals. and they call this looking for cwd
???
‘’An exception to this requirement can be made by the SAHO in the case of a
mass casualty / mortality event such as Hemorrhagic Disease (HD) caused by
(Epizootic Hemorrhagic Disease Virus (EHDV) or bluetongue virus (BTV). In these
events, CWD sample collection can be limited to two (2) animals per
event.’’
absolutely amazing, sad, but amazing.
I wish to update you on the CWD science from the PRION2013 congressional
abstracts, and other related science on the TSE prion disease.
the PRION2013 congressional abstracts on cwd will be toward the bottom,

Quick Shots: Outdoors 16 more CWD deer discovered
Tests for chronic wasting disease found 16 more confirmed cases in northern
Illinois this fall, bringing the total to 163 since the state’s first infected
deer was discovered in 2002 near Roscoe.
The positive tests came from deer killed by firearm and archery hunters and
a few suspicious deer taken by DNR staff.
Winnebago and DeKalb counties each had six; Boone County four.
All but one case was from deer in previously infected areas. The exception
was a deer killed in southern DeKalb County, about seven miles from the LaSalle
County line.
The state has included southern DeKalb in next month’s special CWD hunt
because of the new discovery.
The latest positives came from about 2,500 deer. Tests have not been
completed on all deer sampled during the firearm seasons.
Hunters find more than deer
Deer hunters in Michigan, Arkansas and Tennessee found methamphetamine labs
or their remnants this season, according to Gannett News Services. Meth is an
addictive stimulant made in home labs, which are often hidden in rural settings.
Midwest deer harvests increase
Midwest states had increased firearm deer harvests this season.
Illinois’ total was 115,192 deer, compared with 114,209 last year.
Wisconsin’s harvest was 336,211, compared with 325,630 in 2005.
Michigan’s harvest was up about 7 percent at about 258,000.
Minnesota doesn’t yet have a total but officials expect it to surpass
250,000, which would place it among the state’s five best harvests.
Court rules in muted swan fight
A District of Columbia Circuit Court of Appeals recently ruled in favor of
government agencies’ right to manage muted swans.
An animal-rights group contended the swans were protected under the
Migratory Bird Treaty Act.
Agencies in several states, including Wisconsin, Indiana and Maryland, have
been challenged as they try to control muted swan population.
The swans are considered destructive to the wetland systems. They also are
known to attack nesting native swans and waterfowl.

Subject: ILLINOIS FINDS 16 MORE CASES OF CWD WITH New cases found in
Northern Illinois
Date: January 10, 2006 at 11:57 am PST
FOR IMMEDIATE RELEASE January 9, 2006
DEER SEASON SAMPLING FINDS ADDITIONAL EVIDENCE OF CHRONIC WASTING DISEASE
New cases found in Northern Illinois
SPRINGFIELD, IL. – Sixteen additional cases of chronic wasting disease
(CWD) have been detected in northern Illinois through sampling of
hunter-harvested deer during the state’s 2005-06 deer seasons. The new cases
include two deer taken by hunters in Ogle County, the first time CWD has been
detected there.
“The Department of Natural Resources continues intensive sampling for CWD
as part of our effort to slow the spread of the disease in our wild deer herd,”
said Paul Shelton, manager of the IDNR Forest Wildlife Program. “We appreciate
the support of hunters who continue to voluntarily allow us to take tissue
samples from their deer to test for the disease. The sampling, testing and
surveillance is extremely important as we deal with CWD.”
Chronic wasting disease was first discovered in Illinois in November 2002
and to date Illinois has detected 112 positive cases.
The disease had been confined in northern Illinois in Boone, Winnebago,
McHenry and northern DeKalb until the two new cases were detected in nearby Ogle
County this winter.
“We were somewhat surprised to find these two cases in Ogle County because
no cases had been detected there previously despite very intensive sampling,”
Shelton said. “We’ve sampled nearly 2,000 deer in Ogle County since 2003 and
these are the only two cases we have found there to date. We are still awaiting
the results of approximately 350 other samples from Ogle County taken this
fall.”
Illinois biologists have collected samples from more than 2,500 deer in
seven northern Illinois counties so far during the 2005-06 firearm and archery
deer seasons and from suspect animals reported to the IDNR.
Hunters in Boone, Winnebago and McHenry counties a portion of DeKalb County
north of the East-West Tollway will participate in a CWD Deer Season Jan. 13-15
to help control deer densities and the spread of chronic wasting disease.
Hunters with unfilled 2005 firearm, muzzleloader or archery deer permits valid
for one of the open counties may use those to hunt. Hunters using unfilled
permits from the 2005 firearm, muzzleloader or archery season may take deer
appropriate for that permit (antlerless-only or either-sex). Special CWD season
permits were also issued previously. Check stations will be manned in the four
counties and successful hunters who submit samples for CWD testing will be
provided with an additional permit valid for the remainder of the season.
Confirmed CWD cases by county: Boone-53 Winnebago-42 McHenry-9 Dekalb-6
Ogle-2
Check station locations for the CWD Deer Season:
Boone County - Boone County Fairgrounds, Rt. 76 and Business Rt. 20,
Belvidere. DeKalb County - Potawatomi Woods Forest Preserve, 32199 Kirkland
Rd.(one-quarter mile north of Rt. 72), Kirkland. McHenry County - Sportsman’s
Choice, intersection of Routes 14 and 47, Woodstock. Winnebago County - Rock Cut
State Park, 6425 Hart Rd. (one mile east of Perryville Rd. on Hart Rd.), Loves
Park.
While not thought to be contagious to humans or livestock, CWD is known to
spread from animal to animal among deer and elk. The disease affects the brain
of the infected animal, causing it to become emaciated, display abnormal
behavior, lose coordination and eventually die.
Illinois expanded its chronic wasting disease surveillance effort in 2002
following the discovery of CWD in neighboring Wisconsin. For updated information
about CWD, check the IDNR web site at:
http://dnr.state.il.us/cwd. Hunters who
participated in the CWD sampling can check the status of their deer at this
site. Hunters who provided samples from deer that test positive are notified by
the IDNR.

Subject: 9 NEW CWD CASES FOUND IN NORTHERN ILLINOIS Date: December 20, 2003
at 6:58 pm PST
9 new CWD cases found in northern Illinois DOUG GOODMAN , Rockford Register
Star
Illinois has nine more confirmed cases of a fatal deer disease first
discovered in the state last fall near Roscoe, wildlife officials announced
Friday.
The new cases were found among 1,100 hunter-harvested deer tested for
chronic wasting disease during the first session of the firearm season last
month.
The latest cases include five in Boone County, three in Winnebago County
and the first-ever in DeKalb County. The state now has 30 confirmed cases.
Paul Shelton, state Department of Natural Resources wildlife program
manager, said the DeKalb deer was killed in the county's northern section near
the Kishwaukee River about 20 miles from Roscoe, where the majority of the cases
have been found.
"It's possible it could have traveled from the Roscoe area," he said. "Or
it's possible we could have missed a pocket (of diseased deer) during our
sampling where we don't have as high a prevalence of CWD among the deer. When
more data comes in, we'll get a clearer picture."
The tests also showed CWD in two other new areas -- just west of Rockton
and northeastern Boone County. The Rockton case was the first west of Interstate
90, while the earlier Boone cases were all on the western border along Winnebago
County.
"The numbers in themselves were not surprising. They were in line with what
we expected," Shelton said. "More important than the numbers is the distribution
of the (positive) samples."
The latest results were from tests in Winnebago, Boone, DeKalb, Stephenson,
McHenry and Ogle counties.
About 3,500 samples were taken during the firearms seasons in northern
Illinois, but not all the tests have been completed.
Shelton contacted hunters with deer testing positive Wednesday night.
He added the DNR appreciates the cooperation hunters have provided during
the testing process. "They've been fantastic."
Roscoe hunter Jim Hart said CWD has gained a level of acceptance among the
majority of his colleagues.
"A certain number of hunters have told me they are terrified of (CWD), but
most are accepting of it," he said, adding he knows of some hunters who quit the
sport this year for fear of the disease.

Background:
On November 1, 2002 Illinois Department of Natural Resources officials
received confirmation that chronic wasting disease (CWD) in a wild Illinois deer
had been found for the first time, the result of routine testing of a suspect
animal from Boone County. During the ensuing firearm deer season in November and
December, a total of 4,060 samples were taken from hunterharvested deer in 36
Illinois counties (Fig. 1). The following counties were sampled during that
season: Adams, Boone, Bureau, Carroll, Clark, Clinton, DeKalb, Effingham,
Fayette, Fulton, Hancock, Jefferson, Jo Daviess, Johnson, LaSalle, Lawrence,
Macoupin, Madison, Marion, McHenry, McLean, Ogle, Pike, Pope, Randolph, Rock
Island, Sangamon, Shelby, St. Clair, Stephenson, Union, Vermilion, Washington,
Whiteside, Williamson, and Winnebago. Six additional CWD-positive deer were
identified from these samples. Two clusters of infection were identified - one
located along the Boone-Winnebago county line northeast of Rockford, and the
other southeast of Woodstock in McHenry County (Figure 2).

Figure 3. Locations (to the nearest section) of deer collected for chronic
wasting disease testing after the close of the deer hunting season. Follow-up
Surveillance:
After identification of those areas in which CWD-positive deer were found,
the Department followed up with additional sampling (via sharpshooting) in those
two locations so as to better evaluate the status of CWD in the immediate area.
Sample locations were limited by the distribution of adequate habitat, by
suitability of sites for sharpshooting purposes (i.e., safety), and by the
willingness of landowners to allow access. A few additional samples were
collected from road-killed deer when found in the vicinity of the core sampling
area. In the Winnebago-Boone county area, samples were also taken from a
high-density deer herd several miles to the south. DNR staff contacted potential
landowners, both private and public, in an effort to gain access to suitable
properties. Sampling commenced on February 6 and continued through March 31.
Sharpshooting was normally conducted from late afternoon throughout the night
(but varied by site) by staff of USDA-APHIS Wildlife Services and IDNR.
Samples were collected and tested from 185 deer, including 62 from Boone
County, 29 from McHenry County, and 94 from Winnebago County. Figure 3 depicts
the distribution of samples in those counties. Twenty-seven samples were
collected from an area in southern Winnebago County not considered part of the
primary area of concern for CWD, so these samples will be excluded from analyses
pertaining to CWD prevalence, etc.
None of the 27 samples from southern Winnebago County tested positive for
CWD. In addition, none of the 29 samples from McHenry County were positive. In
the Boone-Winnebago sampling unit, 4 of 78 adult deer (5.1%) and 1 of 51 fawns
(2.0%) were CWD-positive. All positive animals except one originated from
sections already known to contain CWD-infected deer, with the new section being
located just east of Roscoe in Winnebago County. Table 1 presents a summary of
surveillance information found during this follow-up period.

Results of All Random Surveillance Data Combined
We combined the sample/test data from the follow-up surveillance
(sharpshooting) with information gathered during the 2002 firearm deer season.
In order to do this, we limited firearm deer season data to those samples taken
from sections within 2 miles of a known positive section. This resulted in an
additional 56 samples from an approximately 69.5 mi2 area of Boone-Winnebago
counties, and 12 samples from a 38 mi2 portion of McHenry County (Figure 4). All
of the samples from the firearm deer season were from adult deer, as no fawns
were sampled during that season. Results of the combined surveillance testing
are presented in Table 2.

Suspect Animal Surveillance Testing
Deer with clinical signs of illness continue to be submitted for CWD
testing by IDNR field staff. To date, four such deer have been diagnosed as
having CWD. All four originated from the Boone- Winnebago unit.
Surveillance Using Deer Population Control Permits
Four Illinois counties (Cook, DuPage, Kane, and Lake) in northeastern
Illinois are closed to firearm deer hunting, thus precluding the collection of
CWD samples by the same methods as in other counties. In addition, collection of
samples from hunter-harvested deer in other counties is unlikely to provide
significant representation of deer residing in urban/suburban areas. In an
effort to collect samples from such locations, we requested that land-managing
agencies controlling urban/suburban deer herds through the use of a Deer
Population Control Permit (DPCP) collect samples for CWD testing. Participating
permittees were provided supplies and training, as well as assistance in getting
samples to the laboratory.
Approximately 317 samples were collected and tested through the DPCP
program, primarily in northeastern Illinois. Preliminary data indicate that DPCP
samples were taken in Cook (30), DuPage (159), Lake (68), Winnebago (9), and
JoDaviess (51). An additional 5 samples were taken in Lake County in conjunction
with an ongoing research project in Highland Park. None of the samples from any
source were found to be positive for CWD.

Minimum deer densities in the areas of concern were determined by
helicopter surveys flown on 5 March 2003 over snow cover. Minimum

Illinois officials say Chronic Wasting Disease (CWD) in the state appears
to be confined to small areas of Boone, Winnebago, and McHenry counties.
The Illinois department of Natural Resources (DNR) says 185 tissue samples
collected in February 2003 turned up 7 new cases. Forest Program Manager Paul
Shelton says the results are encouraging signs that the state can control the
neurological disease that kills deer.
Shelton says fairly intensive testing has not turned up any cases in
central and southern Illinois.

Another 49 deer with chronic wasting disease have been found in Wisconsin,
all within the area where the brain disease was discovered a year ago, reported
the state Department of Natural Resources (DNR).
The new cases bring the total number of diseased deer found in the Mount
Horeb area to 190, about 2 percent of the deer that were examined, the agency
said. All but 2 of the diseased deer were killed in Dane and Iowa
counties.
The disease that threatens the state's $1 billion hunting industry had
never been found east of the Mississippi River until it was detected 13 months
ago near Mount Horeb in southwestern Wisconsin.
Scientists have tested the brains of 39 012 of the 40 111 hunter-killed
deer statewide and donated for analysis for chronic wasting disease, in an
unprecedented attempt to determine how far the disease had spread into a
whitetail herd estimated at 1.6 million deer, according to the DNR.
The ailment creates sponge-like holes in a deer's brain, causing the animal
to become thin, act abnormally, and die. Scientists believe it is spread by
animal-to-animal contact. There is no scientific evidence it can infect humans,
but people are advised not to eat an infected deer.
Of the diseased deer found so far, 99 were in Iowa County, 89 were in Dane
County, one in Richland County, and one in Sauk County. Only 6 deer with the
disease have been found outside the 411-square-mile eradication zone around
Mount Horeb where the DNR wants all the deer killed to try to wipe out the
disease from the herd. Those 6 were found in the so-called management zone
nearby and suggest that the rate of the infection in that area is 0.10 percent,
the DNR said.
Wildlife officials will make no decision on whether to expand the
eradication zone to include land near those deer until the state Natural
Resources Board acts on some proposed permanent regulations concerning the
disease, DNR spokesman Bob Manwell said.
The Wisconsin Veterinary Diagnostic Laboratory in Madison had reported it
had analyzed all deer samples for the disease. Manwell said getting the final
test results may take another week or 2. The results so far are positive because
the disease seems clustered in a fairly small area, Manwell said.
"We have not found those outliers way out that everybody was kind of
fearful of," he said. "Some of our fears are beginning to lessen a little bit."
The DNR still does not know how the disease got into the herd, Manwell
said.
"We are not anywhere near saying we got this thing in hand or under
control," he said. "Granted, it is a relatively low prevalence in the overall
population. We are going to be watching it carefully over the years to
come."
[Byline: Robert Imrie]
-- ProMED-mail
[Although the Wisconsin DNR is to be commended for its desire to eradicate
the disease, it seems inappropriate to attempt to eradicate all the animals
within a certain designated area. The animals are known to travel some distances
and to jump fences and would not recognize a man-made designated area. A survey
might seem appropriate, but the eradication attempt does not seem well
thought-out, especially in view of the low percentage of positives. -

Illinois Department of Natural Resources
FOR IMMEDIATE RELEASE February 5, 2003
DNR TO DO ADDITIONAL CWD TESTING
SPRINGFIELD, Ill. – The Department of Natural Resources is undertaking
additional testing of white-tailed deer in Boone, McHenry and Winnebago counties
for chronic wasting disease, where seven confirmed cases of CWD have
occurred.
IDNR will be taking samples at Rock Cut State Park in Winnebago County,
owned by the Department; Kinnikinnick Conservation Area owned by the Boone
County Conservation District; and select properties owned by private
individuals. The deer removal is being conducted by teams comprised of USDA
Wildlife Services staff and IDNR biologists. Properties that have been selected
are located in the areas in which CWD-positive deer have been found, and contain
significant blocks of deer habitat where the animals tend to concentrate during
winter.
Chronic wasting disease is a fatal neurological disease found in deer and
elk. The disease affects the brains of infected animals, causing them to become
emaciated, display abnormal behavior, lose coordination and eventually die. It
is not known to be contagious to livestock or humans.
So far, about 3,500 tests for CWD have been completed on the 4,100 samples
taken from hunter-harvested deer. A total of seven deer have tested positive,
including six taken during the firearm deer season in November and December. All
of the positive cases have been in Boone, McHenry and Winnebago counties.
"This additional testing, concentrating on known CWD areas, will allow us
to better assess the status of CWD in northern Illinois," said Paul Shelton,
IDNR's Forest Wildlife Program Manager. Shelton noted that biologists have been
unable to conduct aerial deer population surveys due to a lack of snow cover in
the vicinity of known CWD-positive animals, but they intend to conduct the
surveys as soon as weather conditions allow.
Additional samples will help biologists determine how long CWD may have
been present and the distribution and prevalence of the disease. Sampling is
expected to be completed by the end of February or early March, with results
several weeks later. The test results will help the Department further refine
its strategy for dealing with the disease. The deer carcasses will be held in an
approved facility until CWD test results are available. Deer that test negative
will be processed and donated to food pantries.

NEW EVIDENCE OF SUB-CLINICAL PRION INFECTION: IMPORTANT RESEARCH FINDINGS
RELEVANT TO CJD AND BSE
A team of researchers led by Professor John Collinge at the Medical
Research Council Prion Unit1 report today in the Proceedings of the National
Academy of Sciences, on new evidence for the existence of a 'sub-clinical' form
of BSE in mice which was unknown until now.
The scientists took a closer look at what is known as the 'species barrier'
- the main protective factor which limits the ability of prions2 to jump from
one species to infect another. They found the mice had a 'sub-clinical' form of
disease where they carried high levels of infectivity but did not develop the
clinical disease during their normal lifespan. The idea that individuals can
carry a disease and show no clinical symptoms is not new. It is commonly seen in
conventional infectious diseases.
Researchers tried to infect laboratory mice with hamster prions3 called
Sc237 and found that the mice showed no apparent signs of disease. However, on
closer inspection they found that the mice had high levels of mouse prions in
their brains. This was surprising because it has always been assumed that
hamster prions could not cause the disease in mice, even when injected directly
into the brain.
In addition the researchers showed that this new sub-clinical infection
could be easily passed on when injected into healthy mice and hamsters.
The height of the species barrier varies widely between different
combinations of animals and also varies with the type or strain of prions. While
some barriers are quite small (for instance BSE easily infects mice), other
combinations of strain and species show a seemingly impenetrable barrier.
Traditionally, the particular barrier studied here was assumed to be
robust.
Professor John Collinge said: "These results have a number of important
implications. They suggest that we should re-think how we measure species
barriers in the laboratory, and that we should not assume that just because one
species appears resistant to a strain of prions they have been exposed to, that
they do not silently carry the infection. This research raises the possibility,
which has been mentioned before, that apparently healthy cattle could harbour,
but never show signs of, BSE.
"This is a timely and unexpected result, increasing what we know about
prion disease. These new findings have important implications for those
researching prion disease, those responsible for preventing infected material
getting into the food chain and for those considering how best to safeguard
health and reduce the risk that theoretically, prion disease could be contracted
through medical and surgical procedures."

Professor Collinge is a consultant neurologist and Director of the newly
formed MRC Prion Unit based at The Imperial College School of Medicine at St
Mary's Hospital. He is also a member of the UK Government's Spongiform
Encephalopathy Advisory Committee (SEAC). The MRC prion unit is was set up in
1999, and its work includes molecular genetic studies of human prion disease and
transgenic modelling of human prion diseases.
Prions are unique infectious agents that cause fatal brain diseases such as
Creutzfeldt-Jakob disease (CJD) in humans and scrapie and BSE (mad cow disease)
in animals. In some circumstances prions from one species of animals can infect
another and it is clear that BSE has done this to cause the disease variant CJD
in the UK and France. It remains unclear how large an epidemic of variant CJD
will occur over the years ahead.
The strain of prion used here to infect the mice is the Sc237 strain (also
known as 263K) which infects hamsters, and until now was assumed not to infect
mice.
This research was funded by the Medical Research Council and Wellcome
Trust.
The Medical Research Council (MRC) is a national organisation funded by the
UK tax-payer. Its business is medical research aimed at improving human health;
everyone stands to benefit from the outputs. The research it supports and the

Subject: CWD--ILLINOIS--THREE MORE POSITIVE CWD CASES FOUND !!!
Date: December 16, 2002 at 12:44 pm PST
Illinois Department of Natural Resources
FOR IMMEDIATE RELEASE December 16, 2002
THREE MORE POSITIVE CWD CASES FOUND IN ILLINOIS
SPRINGFIELD, ILL. – Chronic wasting disease (CWD) has been detected in
three more deer in northern Illinois, the Department of Natural Resources
announced today, bringing to four the number of confirmed cases of the disease
in Illinois. CWD is not known to be contagious to livestock or humans.
Two of the three new cases were found in the vicinity of the first CWD case
reported in early November. One positive case each was returned from Boone,
McHenry and Winnebago counties. This represents the second instance of a
CWD-positive deer in Boone County. (Illinois'first case, originally reported as
from Winnebago County, actually was just over the county line in Boone County).
The locations of the three cases reported to date within Boone and Winnebago
counties are within approximately two miles of each other in an area east of
Roscoe, Illinois. The McHenry County positive deer came from an area a few miles
northeast of Woodstock. The new cases include a 2.5-year-old buck (Boone), 1.5
year-old-buck (McHenry) and a 1.5-year-old doe (Winnebago).
The samples were taken as part of IDNR's CWD surveillance of deer harvested
during the firearm deer season. Testing was conducted at the Illinois Department
of Agriculture Disease Laboratories. A follow-up test on the McHenry County case
was conducted at the National Veterinary Services Laboratory in Ames, Iowa,
confirming the diagnosis. Follow-up tests on the Boone and Winnebago county
animals were deemed unnecessary, given their location and the contagious nature
of the disease.
"It comes as no surprise that we found additional cases near the first
one," said IDNR Director Brent Manning. "The identification of a new location in
McHenry County, although an unwelcome result, does demonstrate that our
surveillance program is proving effective. We will continue to study results as
they come in, in order to incorporate the best science into our response
strategies."
Illinois expanded its surveillance efforts regarding CWD earlier this year
and created a joint task force with the Departments of Natural Resources and
Agriculture following the CWD outbreak in southern Wisconsin. About 4,000
samples of hunter-harvested deer were taken in 36 counties around Illinois
during the firearm deer season Nov. 22-24 and Dec.5-8. Tests have been completed
on about 1,450 samples, with only the three positive results.
"We continue to be committed to a long-term plan of stepped up surveillance
and monitoring and taking all steps biologically appropriate to combat chronic
wasting disease in Illinois. Deer hunters and those who value the health of
wildlife and outdoor recreation in Illinois played an important role during the
firearm season and will continue to play an important role in that
process."
Counties sampled for CWD during the 2002 firearm deer hunting season
included: Jo Daviess, Stephenson, Winnebago, Boone, McHenry, Carroll, Ogle,
DeKalb, Whiteside, Rock Island, Bureau, LaSalle, Hancock, Adams, Pike, Fulton,
McLean, Vermilion, Sangamon, Macoupin, Shelby, Fayette, Effingham, Clark,
Lawrence, Madison, St. Clair, Clinton, Washington, Randolph, Jefferson, Marion,
Williamson, Union, Johnson and Pope. Counties were selected based on a variety
of factors including geographic location, size of deer population and the number
of facilities with captive deer or elk.
Chronic wasting disease is a fatal neurological disease found in deer and
elk. The disease affects the brains of infected animals, causing them to become
emaciated, display abnormal behavior, lose coordination and eventually die. It
is not known to be contagious to livestock or humans.
CWD has been diagnosed in wild, free-ranging deer and elk as well as in
captive animals in a number of western states but earlier this year was found in
neighboring Wisconsin and Minnesota.

FOR IMMEDIATE RELEASE November 1, 2002
POSITIVE CWD CASE FOUND IN ILLINOIS
SPRINGFIELD, ILL. ? Chronic wasting disease (CWD) has been detected in a
sample from a wild deer near Roscoe in Winnebago County, the Department of
Natural Resources announced today. CWD is not known to be contagious to
livestock or humans.
The young female deer was shot by a landowner in late October because he
believed it was ill. DNR Conservation Police officers were contacted and
collected the doe for testing at the Illinois Department of Agriculture
laboratory in Centralia. A follow-up test conducted today at the National
Veterinary Services Laboratory in Ames, Iowa, confirmed the diagnosis.
"This is the first positive for CWD from any deer or elk in Illinois,
though we've been monitoring and testing for the disease for the past five
years," said IDNR Director Brent Manning. "Illinois expanded its surveillance
efforts earlier this year and created a joint task force with the Departments of
Natural Resources and Agriculture following the CWD outbreak in southern
Wisconsin."
"The detection of CWD in Winnebago County is disappointing," Manning said.
"We are committed to a long-term plan of stepped up surveillance and monitoring
and to taking all steps biologically appropriate to control the spread of
chronic wasting disease in Illinois. Deer hunters and those who value the health
of wildlife and outdoor recreation in Illinois will continue to play an
important role in that process."
Extensive testing for the disease is planned during Illinois' firearm deer
season, which begins Friday, Nov. 22. About 3,500 samples in 36 counties from
hunter- harvested deer around Illinois will be collected and tested. Larger
numbers of samples from hunter-harvested deer are being collected in northern
Illinois. Additional samples also are being taken from deer control programs in
northeastern Illinois where firearm deer hunting is not allowed.
Counties tentatively to be sampled for CWD during the 2002 firearm deer
hunting season include Jo Daviess, Stephenson, Winnebago, Boone, McHenry,
Carroll, Ogle, DeKalb, Whiteside, Rock Island, Bureau, LaSalle, Hancock, Adams,
Pike, Fulton, McLean, Vermilion, Sangamon, Macoupin, Shelby, Fayette, Effingham,
Clark, Lawrence, Madison, St. Clair, Clinton, Washington, Randolph, Jefferson,
Marion,Williamson, Union, Johnson and Pope. Counties were selected based on a
variety of factors including geographic location, size of deer population and
the number of facilities with captive deer or elk.
"Once we get test results back from our expanded surveillance efforts the
task force will be able to evaluate the extent of the disease in Illinois and
the necessary steps to control the disease," Manning said.
Chronic wasting disease is a fatal neurological disease found in deer and
elk. The disease affects the brains of infected animals, causing them to become
emaciated, display abnormal behavior, lose coordination and eventually die. It
is not known to be contagious to livestock or humans.
CWD has been diagnosed in wild, free-ranging deer and elk as well as in
captive animals in a number of western states but earlier this year was found in
neighboring Wisconsin and Minnesota. Illinois has been testing suspect animals
for the last five years, as well as taking samples during deer hunting
season.
A task force, comprised of key staff from both agencies, has been working
for months to develop plans to address surveillance of wild deer and captive
herds, import and export of deer and elk and a planned response to a potential
chronic wasting disease outbreak in Illinois.
The importation of hunter-harvested deer and elk is being limited, the
importation of live animals has been restricted and the feeding of wild deer has
been banned.
A DNR rule bans the importation of hunter-harvested deer and elk carcases
into Illinois, except for deboned meat, antlers, antlers attached to skull caps,
hides, upper canine teeth, and finished taxidermist mounts. Skull caps must be
cleaned of all brain and muscle tissue. This action prevents hunters from
bringing potentially diseased animals into Illinois and discarding their parts
in a manner that could result in contamination of Illinois' deer herd.
The Department has banned the feeding of wild deer and other wildlife in
areas where wild deer are present. The ban includes food, salt, mineral blocks
and other food products, with some exceptions. For example, bird and squirrel
feeders close to homes and incidental feeding of wildlife within active
livestock operations, are exempt from the ban. For a complete list of the
exemptions see the rule on the Department's web site.
The Department has also implemented regulations to minimize the threat of
chronic wasting disease entering Illinois through the interstate transportation
of captive deer and elk and to monitor captive herds already in Illinois. DNR
shares responsibility with the Department of Agriculture in regulating captive
deer and elk on game farms. DNR's new rule complements new regulations being
adopted by the Agriculture Department for diseased animals.

Wasting disease found in northern Illinois deer
A variant of mad-cow, the illness is fatal to cervids
November 2, 2002
By JEFF LAMPE of the Journal Star
PEORIA - The news Illinois deer hunters and wildlife officials have been
dreading all fall became official Friday when a Winnebago County white-tailed
deer tested positive for chronic wasting disease.
The young female deer shot by a landowner northeast of Rockford is the
first Illinois animal to test positive for chronic wasting disease - a fatal
neurological malady first found in Colorado elk in the 1960s.
Though the result was not unexpected, given a similar discovery last
February in southern Wisconsin, Friday's news was not welcomed by wildlife
officials.
"The detection of CWD in Winnebago County is disappointing," said Brent
Manning, director of the Illinois Department of Natural Resources. "We are
committed to a long-term plan of stepped-up surveillance and monitoring to
control the spread of this disease."
CWD is a variant of mad-cow disease caused by an abnormally shaped protein
that damages brain and nerve tissue. So far there is no scientific evidence
indicating CWD is transmissible to humans.
"The first thing I would say is I personally eat venison," Manning said.
"Secondly, there have been no confirmed cases of this disease being passed into
the human population."
Similar sentiments have not eased the fears of some residents of Wisconsin.
The disease was first found in that state near Mount Horeb, 40 miles north of
the Illinois border.
Sales of hunting licenses are down 23 percent in the months since and
revenues for the Wisconsin DNR have dropped by $3.8 million. And many Wisconsin
citizens expressed outrage at that state's plan to kill every deer in a
361-square-mile area around Mount Horeb.
Illinois officials said Friday they have no plans to initiate a similar
eradication plan in Winnebago County. Officials also stressed that Illinois'
230,000 deer hunters need not panic.
"One deer doesn't mean an epidemic. So we're taking this one step at a
time," said John Buhnerkempe, head of the DNR's wildlife division. "I feel
strongly the best approach is to take a very deliberate approach and not do
anything extraordinary at this point and time."
To gauge the scope of the disease, the DNR plans to sample at least 3,500
deer during the shotgun hunting season.
Hunters are also asked to report any animals they see showing signs of
emaciation, staggering, consuming large amounts of water, urinating excessively
or generally showing a lack of wariness.
"After we gather data and apply the best science we have to that
information we'll figure out how to deal with this disease and how to manage it
for the state," Buhnerkempe said.
Beyond that, officials urge hunters to follow basic precautions when
handling deer they shoot.
Preliminary indications from some hunters in Winnebago County is that they
still plan to head afield. Archery season has been under way in Illinois since
Oct. 1 and the first shotgun season runs Nov. 22-24.
"We were all pretty much hoping it wasn't here," said Robert Erb of
Rockford, a long-time bowhunter. "But I don't think people are going to quit
hunting. Unless it starts showing up more."
That possibility certainly exists.
Test results are still pending for an animal shot this week by conservation
police officer Steve Vasicek near Tremont.
"It was emaciated and sick looking and would let me walk to within 10 yards
of it before it would startle and run," Vasicek said.
That description is similar to the one called in Oct. 25 by the Winnebago
County landowner who lived near the city of Roscoe.
"The farmer said the deer was sick and looked emaciated and let him walk
right to it before he shot it," said Lt. William Shannon, a conservation police
officer.
Tests conducted at both the Illinois Department of Agriculture laboratory
in Centralia and the National Veterinary Services Laboratory in Ames, Iowa,
confirmed the disease.
As a result, Illinois joins the ranks of 10 other states and two Canadian
provinces that have discovered CWD in deer or elk within their borders.

The Fight to Keep Chronic Wasting Disease Out of Florida
*** The potential impact of prion diseases on human health was greatly
magnified by the recognition that interspecies transfer of BSE to humans by beef
ingestion resulted in vCJD. While changes in animal feed constituents and
slaughter practices appear to have curtailed vCJD, there is concern that CWD of
free-ranging deer and elk in the U.S. might also cross the species barrier.
Thus, consuming venison could be a source of human prion disease. Whether BSE
and CWD represent interspecies scrapie transfer or are newly arisen prion
diseases is unknown. Therefore, the possibility of transmission of prion disease
through other food animals cannot be ruled out. There is evidence that vCJD can
be transmitted through blood transfusion. There is likely a pool of unknown size
of asymptomatic individuals infected with vCJD, and there may be asymptomatic
individuals infected with the CWD equivalent. These circumstances represent a
potential threat to blood, blood products, and plasma supplies.
pens, pens, PENS ???
*** Spraker suggested an interesting explanation for the occurrence of CWD.
The deer pens at the Foot Hills Campus were built some 30-40 years ago by a Dr.
Bob Davis. At or abut that time, allegedly, some scrapie work was conducted at
this site. When deer were introduced to the pens they occupied ground that had
previously been occupied by sheep.

PO-039: A comparison of scrapie and chronic wasting disease in white-tailed
deer
Justin Greenlee, Jodi Smith, Eric Nicholson US Dept. Agriculture;
Agricultural Research Service, National Animal Disease Center; Ames, IA USA
snip...
The results of this study suggest that there are many similarities in the
manifestation of CWD and scrapie in WTD after IC inoculation including early and
widespread presence of PrPSc in lymphoid tissues, clinical signs of depression
and weight loss progressing to wasting, and an incubation time of 21-23 months.
Moreover, western blots (WB) done on brain material from the obex region have a
molecular profile similar to CWD and distinct from tissues of the cerebrum or
the scrapie inoculum. However, results of microscopic and IHC examination
indicate that there are differences between the lesions expected in CWD and
those that occur in deer with scrapie: amyloid plaques were not noted in any
sections of brain examined from these deer and the pattern of immunoreactivity
by IHC was diffuse rather than plaque-like. After a natural route of exposure,
100% of WTD were susceptible to scrapie. Deer developed clinical signs of
wasting and mental depression and were necropsied from 28 to 33 months PI.
Tissues from these deer were positive for PrPSc by IHC and WB. Similar to IC
inoculated deer, samples from these deer exhibited two different molecular
profiles: samples from obex resembled CWD whereas those from cerebrum were
similar to the original scrapie inoculum. On further examination by WB using a
panel of antibodies, the tissues from deer with scrapie exhibit properties
differing from tissues either from sheep with scrapie or WTD with CWD. Samples
from WTD with CWD or sheep with scrapie are strongly immunoreactive when probed
with mAb P4, however, samples from WTD with scrapie are only weakly
immunoreactive. In contrast, when probed with mAb’s 6H4 or SAF 84, samples from
sheep with scrapie and WTD with CWD are weakly immunoreactive and samples from
WTD with scrapie are strongly positive. This work demonstrates that WTD are
highly susceptible to sheep scrapie, but on first passage, scrapie in WTD is
differentiable from CWD.

Scrapie in Deer: Comparisons and Contrasts to Chronic Wasting Disease (CWD)
Justin J. Greenlee of the Virus and Prion Diseases Research Unit, National
Animal Disease Center, ARS, USDA, Ames, IA

This highlights the facts that 1) prior to the onset of clinical signs
PrPSc is widely distributed in the CNS and lymphoid tissues and 2) currently
used diagnostic methods are sufficient to detect PrPSc prior to the onset of
clinical signs. The results of this study suggest that there are many
similarities in the manifestation of CWD and scrapie in white-tailed deer after
IC inoculation including early and widespread presence of PrPSc in lymphoid
tissues, clinical signs of depression and weight loss progressing to wasting,
and an incubation time of 21-23 months. Moreover, western blots (WB) done on
brain material from the obex region have a molecular profile consistent with CWD
and distinct from tissues of the cerebrum or the scrapie inoculum. However,
results of microscopic and IHC examination indicate that there are differences
between the lesions expected in CWD and those that occur in deer with scrapie:
amyloid plaques were not noted in any sections of brain examined from these deer
and the pattern of immunoreactivity by IHC was diffuse rather than plaque-like.
After a natural route of exposure, 100% of white-tailed deer were susceptible to
scrapie. Deer developed clinical signs of wasting and mental depression and were
necropsied from 28 to 33 months PI. Tissues from these deer were positive for
scrapie by IHC and WB. Tissues with PrPSc immunoreactivity included brain,
tonsil, retropharyngeal and mesenteric lymph nodes, hemal node, Peyer’s patches,
and spleen. While two WB patterns have been detected in brain regions of deer
inoculated by the natural route, unlike the IC inoculated deer, the pattern
similar to the scrapie inoculum predominates.

2011 Annual Report
In Objective 1, Assess cross-species transmissibility of transmissible
spongiform encephalopathies (TSEs) in livestock and wildlife, numerous
experiments assessing the susceptibility of various TSEs in different host
species were conducted. Most notable is deer inoculated with scrapie, which
exhibits similarities to chronic wasting disease (CWD) in deer suggestive of
sheep scrapie as an origin of CWD.
snip...
4.Accomplishments 1. Deer inoculated with domestic isolates of sheep
scrapie. Scrapie-affected deer exhibit 2 different patterns of disease
associated prion protein. In some regions of the brain the pattern is much like
that observed for scrapie, while in others it is more like chronic wasting
disease (CWD), the transmissible spongiform encephalopathy typically associated
with deer. This work conducted by ARS scientists at the National Animal Disease
Center, Ames, IA suggests that an interspecies transmission of sheep scrapie to
deer may have been the origin of CWD. This is important for husbandry practices
with both captive deer, elk and sheep for farmers and ranchers attempting to
keep their herds and flocks free of CWD and scrapie.
White-tailed Deer are Susceptible to Scrapie by Natural Route of Infection
Jodi D. Smith, Justin J. Greenlee, and Robert A. Kunkle; Virus and Prion
Research Unit, National Animal Disease Center, USDA-ARS

This work demonstrates for the first time that white-tailed deer are
susceptible to sheep scrapie by potential natural routes of inoculation.
In-depth analysis of tissues will be done to determine similarities between
scrapie in deer after intracranial and oral/intranasal inoculation and chronic
wasting disease resulting from similar routes of inoculation.

*** DEFRA U.K. What is the risk of Chronic Wasting Disease CWD being
introduced into Great Britain? A Qualitative Risk Assessment October 2012
snip...
In the USA, under the Food and Drug Administration’s BSE Feed Regulation
(21 CFR 589.2000) most material (exceptions include milk, tallow, and gelatin)
from deer and elk is prohibited for use in feed for ruminant animals. With
regards to feed for non-ruminant animals, under FDA law, CWD positive deer may
not be used for any animal feed or feed ingredients. For elk and deer considered
at high risk for CWD, the FDA recommends that these animals do not enter the
animal feed system. However, this recommendation is guidance and not a
requirement by law.
Animals considered at high risk for CWD include:
1) animals from areas declared to be endemic for CWD and/or to be CWD
eradication zones and
2) deer and elk that at some time during the 60-month period prior to
slaughter were in a captive herd that contained a CWD-positive animal.
Therefore, in the USA, materials from cervids other than CWD positive
animals may be used in animal feed and feed ingredients for non-ruminants.
The amount of animal PAP that is of deer and/or elk origin imported from
the USA to GB can not be determined, however, as it is not specified in TRACES.
It may constitute a small percentage of the 8412 kilos of non-fish origin
processed animal proteins that were imported from US into GB in 2011.
Overall, therefore, it is considered there is a __greater than negligible
risk___ that (nonruminant) animal feed and pet food containing deer and/or elk
protein is imported into GB.
There is uncertainty associated with this estimate given the lack of data
on the amount of deer and/or elk protein possibly being imported in these
products.
snip...
36% in 2007 (Almberg et al., 2011). In such areas, population declines of
deer of up to 30 to 50% have been observed (Almberg et al., 2011). In areas of
Colorado, the prevalence can be as high as 30% (EFSA, 2011). The clinical signs
of CWD in affected adults are weight loss and behavioural changes that can span
weeks or months (Williams, 2005). In addition, signs might include excessive
salivation, behavioural alterations including a fixed stare and changes in
interaction with other animals in the herd, and an altered stance (Williams,
2005). These signs are indistinguishable from cervids experimentally infected
with bovine spongiform encephalopathy (BSE). Given this, if CWD was to be
introduced into countries with BSE such as GB, for example, infected deer
populations would need to be tested to differentiate if they were infected with
CWD or BSE to minimise the risk of BSE entering the human food-chain via
affected venison.
snip...
The rate of transmission of CWD has been reported to be as high as 30% and
can approach 100% among captive animals in endemic areas (Safar et al., 2008).
snip...
In summary, in endemic areas, there is a medium probability that the soil
and surrounding environment is contaminated with CWD prions and in a
bioavailable form. In rural areas where CWD has not been reported and deer are
present, there is a greater than negligible risk the soil is contaminated with
CWD prion.
snip...
In summary, given the volume of tourists, hunters and servicemen moving
between GB and North America, the probability of at least one person travelling
to/from a CWD affected area and, in doing so, contaminating their clothing,
footwear and/or equipment prior to arriving in GB is greater than negligible.
For deer hunters, specifically, the risk is likely to be greater given the
increased contact with deer and their environment. However, there is significant
uncertainty associated with these estimates.
snip...
Therefore, it is considered that farmed and park deer may have a higher
probability of exposure to CWD transferred to the environment than wild deer
given the restricted habitat range and higher frequency of contact with tourists
and returning GB residents.

***Evaluation of the Zoonotic Potential of Transmissible Mink
Encephalopathy
We previously described the biochemical similarities between PrPres derived
from L-BSE infected macaque and cortical MM2 sporadic CJD: those observations
suggest a link between these two uncommon prion phenotypes in a primate model
(it is to note that such a link has not been observed in other models less
relevant from the human situation as hamsters or transgenic mice overexpressing
ovine PrP [28]). We speculate that a group of related animal prion strains
(L-BSE, c-BSE and TME) would have a zoonotic potential and lead to prion
diseases in humans with a type 2 PrPres molecular signature (and more
specifically type 2B for vCJD)
snip...
Together with previous experiments performed in ovinized and bovinized
transgenic mice and hamsters [8,9] indicating similarities between TME and
L-BSE, the data support the hypothesis that L-BSE could be the origin of the TME
outbreaks in North America and Europe during the mid-1900s.
