Fatal neurological disease CWD of deer turns into a zombie, struck a number of regions of the United States, especially Minnesota and Wyoming, and can spread to humans.
According to the Centers for control and prevention of diseases, as of January 24 States, including new York, reported multiple cases of CWD in deer and elk. As stated in their report, in some places, where there is a disease, the infection rate may exceed 10%, and in some locations more than 25%. CWD called chronic debilitating disease that affects deer and elk and causes animals dramatically lose weight and to walk in circles. Other symptoms include loss of fear of man, stumbling and lethargy.
Confirmed cases of human infection yet, but experts from the University of Minnesota suggest not to relax. On Thursday they were informed about the threat of legislators meeting in the Capitol of Minnesota. The disease spreads through extremely tough protein molecules known as prions, and, being passed through eating infected venison to people, can be no less dangerous than mad cow disease. Prions are virtually indestructible, able to withstand temperatures much above 1000 degrees — and unlike viruses, prions CWD remain viable in the wild for many years, sitting in the mud, being soaked up by plant roots and can even just relax on inanimate objects.
Michael Osterholm, Director of the Center for research and policy in infectious disease in the United States, which dealt with the problems of mad cow disease (BSE) in the Twin Cities says:
“If Stephen king could write a novel about infectious disease, he would have written about prions such as this. It is my confident professional judgement, based on my experience in the field of public health and the risk of transfer of diseases from animals to humans in the 1980-ies and 1990-ies, as well as on my extensive review and evaluation of laboratory studies… likely cases of CWD in humans associated with the consumption of contaminated meat, will be documented in the near future. It is possible that the number of human cases will be significant and not an isolated phenomenon.”
Problem concerned and in Canada, where experimentally fed infected meat, deer, monkeys, after which they had a neurological disorder.
The US centers for control and prevention of diseases and the world health organization recommends not eating deer infected with CWD. But the hunter to determine the presence of deer CWD difficult, the threat has not been proven formally, and many continue to use the venison for food.
