While experts remain uncertain about the potential transmission of "zombie deer disease" to humans, they express concern regarding the increasing number of cases and the possibility of humans being affected by exposure to infected deer.
Scientists are still investigating the likelihood of humans contracting the illness, which is being likened to mad cow disease.
Jennifer Mullinax, an associate professor of wildlife ecology and management at the University of Maryland, stated to the BBC, "As of yet, there has been no transmission from deer or elk to humans." Nevertheless, she emphasized the importance of preventing any prion disease from entering the food chain, supported by the CDC and other agencies.
Research presented by Michael Osterholm, the director of the Center for Infectious Disease Research and Policy, suggests that any documented transmission to humans would pose a crisis.
The research underscores the need for agencies to be ready for the catastrophic outcomes if the disease spreads to humans or production animals, such as cattle. It also warns that the escalating spread could give rise to new strains.
According to the presentation, "To date, ten chronic wasting disease (CWD strains) have been characterized." It highlights the expanding range of CWD in North America and its presence in South Korea and Scandinavian countries, which could potentially result in millions of deer infected with CWD.
USA YEPPOST attempted to contact Osterholm and other members of the Center for Infectious Disease Research and Policy but has not received a response at this time.
What is 'zombie deer disease'?
Chronic wasting disease, also referred to as CWD, belongs to the category of prion diseases, which are rare, progressive neurodegenerative disorders. While there is uncertainty regarding the potential transmission of this specific strain to humans, prion diseases in general can impact both humans and animals.
Mad cow disease serves as an example of a prion disease that can spread from cattle to humans.
According to the CDC, CWD affects various animals including deer, elk, reindeer, sika deer, and moose. Afflicted animals have been identified in Canada, the United States, Norway, and South Korea.
How does 'zombie deer disease' spread?
Scientists believe that the proteins responsible for the disease, known as prions, spread through various bodily fluids, including:
- Feces
- Saliva
- Blood
- Urine
