Over the following two decades, cases of CWD were reported in the surrounding areas, and, as of January 2019, the disease has been documented in 24 states across the continental United States among free-ranging animals.
"So far, there have not been any reported cases contagious to people, but this is a disease that happens very slowly and it could show up years from now", he said.
The disease is fatal to animals as there is no treatments or vaccines.
Symptoms include emaciation from forgetting to eat, stumbling, aggression, lack of fear of people, excessive thirst or urination, and excessive drooling.
The CDC has just issued a warning about the new Chronic Wasting Disease, or "zombie deer disease".
Truth is this isn't even a new report from the CDC.
Heres how you can stop Facebook tracking your location all the time
If you receive the notification with the header: "A New Background Location Setting to Give You More Control", you're good to go. From some years, Facebook has remained on limelight, due to its data tracking issue and extracting user's personal info.
Yet, animal experts say calling them "zombies" is inaccurate - infected deer are non-violent, weak and confused. According to the CDC, the disease gets its start infecting prion proteins in the brain, and is passed through contact with contaminated body fluids and tissue. The disease attacks the animals' brains.
At present, there is little solid evidence proving whether or not chronic wasting disease could be spread to humans, but the World Health Organization has emphasized the importance of keeping the agents of all prion diseases away from the human food chain.
There is no known case of CWD in a human.
A number of cases have been reported in almost three dozen Missouri counties. According to the Alliance for Public Wildlife, between 7,000 to 15,000 animals infected with CWD are eaten every year, with that figure only set to rise, USA Today reported.
If CWD could cause disease in humans, the most likely route of infection would be via eating infected deer or elk meat.
