Europe Chronic Wasting Disease CWD TSE Prion Update August 2019
Europe Chronic Wasting Disease CWD TSE Prion Update August 2019
Map of Chronic Wasting Disease (CWD)
Since the fall of 2016, SVA investigates wild deer found dead or diseased for CWD. During the moose hunting season in 2017, samples were in addition analysed from healthy moose hunted in the county of Jämtland. Since the fall of 2018, road killed deer are also included in the surveillance. On the map you find all investigated wild deer, and the results of the analyses performed.
In March 2019, SVA diagnosed the first case of CWD in Sweden. A 16-year-old emaciated female moose (Alces alces) was found in the municipality of Arjeplog in the county of Norrbotten, circling and with loss of shyness towards humans, possibly blind. The moose was euthanised, and the head was sent for CWD screening in the national CWD surveillance program. The brainstem tissue, but not lymph nodes, were positive for CWD (confirmed with Western Blot).
In May 2019, a second case of CWD was detected in Sweden. As in the first case, it was a 16-year-old female moose in Norrbotten county. The moose was euthanised after being observed emaciated, and with behavioural changes. Similar to the first case, the brainstem tissue, but not lymph nodes, were positive for CWD (confirmed with Western Blot).
The circumstances of the Swedish cases are similar to the CWD cases in moose in both Norway and Finland.
Now surveillance of emaciation disease (CWD) in deer animals is being expanded
2019-07-15
The disease Chronic Wasting Disease (CWD) was first detected in Europe in 2016. The EU then decided on a general surveillance in six Member States, including Sweden. During the sampling, CWD was discovered in the spring of 2019 at two older moose cows in Arjeplog and Arvidsjaur respectively. As a result, an increased sampling is now to take place in the area concerned.
- When a case of CWD is detected in the EU program, sampling should be expanded in the area where the disease has been found. More samples provide better evidence to assess the spread of the disease in the area and possible infectiousness. Therefore, there is a requirement in EU legislation for increased sampling in the case of CWD finds, says Maria Cedersmyg at the Swedish Board of Agriculture.
Moose and reindeer should be tested
There are indications that the CWD that has been demonstrated in Sweden is not contagious, but that the disease can also occur as age changes. Sampling can provide new information about the disease and provide a basis for an assessment of possible infectiousness.
The Swedish Board of Agriculture has decided that sampling should be extended in the moose breeding area where the diseased elk were found, and that it should include moose and reindeer, which are the only susceptible species in the area. The sampling shall include the moose that are older than one year and will be shot in the moose hunting 2019-2020. In addition, some of the reindeer slaughtered during the 2019-2020 slaughter season from the same area will be tested.
Reindeer samples can be distributed over several seasons
The Swedish Board of Agriculture has estimated that more than 4,400 reindeer will be tested, of which 1,480 during the 2019 - 2020 season. The result of the monitoring will be evaluated and a new decision on sampling for additional seasons will be taken in order to achieve the desired total number within a reasonable period of time. If a Sami village chooses to take all the samples now, based on the current state of knowledge, you will not have to take any samples in the coming seasons.
The Swedish Agricultural Agency provides support during the sampling
Sampling will constitute some additional steps in the slaughter, and the authorities will take measures to facilitate sampling. Among other things, the National Veterinary Institute (SVA) will provide sampling material, the Swedish Agricultural Agency will provide training for samplers, and the possibilities for assisting the Sami villages with logistics and cold storage of the carcasses awaiting trial response are being considered.
It will also be possible to apply for compensation for any extra costs incurred as a result of the sampling. More information about it will be posted on the Swedish Agricultural Agency's website.
General sampling continues throughout the country
The general sampling of moose, reindeer, red deer and deer in the EU CWD monitoring program continues as usual. All at risk animals, ie animals that show signs of illness, are found dead or are killed or alternatively die due to a traffic accident, must be tested throughout the country. The monitoring program runs until 2020.
- Here we are still dependent on the public's help. We ask anyone who encounters a risk animal to contact SVA for information on sampling, ”says Maria Cedersmyg.
Facts about CWD
CWD, which is also referred to as a dermal disease, is a serious prion disease of the type transmissible spongiform encephalopathy (TSE) that affects the central nervous system of deer animals. It is characterized by changes in the brain as a result of the accumulation of defective, infectious proteins. The incubation period is at least one year.The most prominent symptoms are emaciation, behavioral changes and movement disorders that increase over time. The disease is fatal.
The disease can be contaminated by direct contact between animals, but also indirectly by diseased animals secreting the agent into saliva, urine and faeces which then contaminate feed, water and soil. The infection can survive a very long time in the environment.
There are several variants of TSE disease in both animal and human. Although CWD has not been established in humans, it is recommended that you do not eat meat from animals with proven CWD.

Camel prion disease detected in Tunisian camels
Camel prion disease detected in Tunisian camels
A novel prion disease first reported in three dromedary camels in Algeria in 2018 has now been detected in dromedaries in Tunisia, the second country to be affected within a year, ProMED Mail, the online reporting system of the International Society for Infectious Diseases, reported yesterday.
The Tunisian detection and the latest information about the disease, called camel prion disease (CPD) and sometimes referred to as "mad camel disease", came from a presentation at the Mediterranean Animal Health Network meeting, held in Cairo on Jun 26 and 27. According to the meeting presentation, CPD is spreading rapidly in the Ouargla region of Algeria where the disease was first identified in older camels at a slaughterhouse.
The scientists who presented at the meeting also said preliminary results suggest that the CPD prion is different from scrapie and bovine spongiform encephalitis (BSE, or "mad cow disease").
A comment from the ProMED Mail moderator Arnon Shimshony, DVM, associate professor of veterinary medicine at Hebrew University of Jerusalem, notes that the area where CPD was first found in Algeria is about 174 miles from the Tunisian border.
In the initial report on the first detection in Algerian camels, published in April 2018 in Emerging Infectious Diseases, described disease-specific prion protein in brain tissues from symptomatic camels, including positive samples in lymph nodes, suggesting infection. The moderator also requested more details about the detections in Tunisia, including location, clinical signs, and ages and origins of affected camels.
