Zombie deer disease, also known as chronic wasting disease (CWD), has stirred significant concern among scientists and the public alike, given its potential implications for animal-to-human transmission.

Despite the absence of human cases thus far, the escalating number of CWD instances in deer populations across various regions, including the US, Canada, Norway, and South Korea, prompts a critical question: could humans be at risk?

What Is Chronic Wasting Disease?
Chronic wasting disease is a prion disease affecting deer, elk, reindeer, sika deer, and moose. Prions, misfolded proteins that cause diseases, are at the heart of CWD. Unlike other pathogens such as bacteria and viruses, prions spread through direct contact with infected animals' faeces, saliva, blood, and urine. The US Department of Agriculture's Animal and Plant Health Inspection Service highlights that CWD is caused by a naturally occurring protein that turns infectious upon misfolding, leading to the degeneration of brain cells and ultimately, the animal's death.

Research On Transmission To Humans
Scientists are diligently investigating whether CWD could pose a risk to humans, drawing parallels with the transmission of mad cow disease from cattle to humans. Jennifer Mullinax, an associate professor at the University of Maryland, stated in a BBC interview, "As of yet, there has been no transmission from deer or elk to humans." The concern revolves around prions' ability to infect humans, similar to other prion diseases that have affected both animals and humans detrimentally. The Centers for Disease Control and Prevention (CDC) supports efforts to prevent any prion disease from entering the food chain.

Potential For Human Exposure
Recent surveillance in Alberta, Canada, revealed a 23% positivity rate for CWD in mule deer. This increase underscores the importance of ongoing research into CWD's transmissibility to humans. Michael Osterholm, Director of the Center for Infectious Disease Research and Policy at the University of Minnesota, emphasized the need for further investigation, particularly concerning potential exposure via contaminated soil or water. Despite structural differences between CWD prions and those responsible for mad cow disease, the risk to humans remains a critical area of study.

In summary, while the current body of research does not conclusively indicate that CWD can be transmitted to humans, the rising incidence of the disease and its similarities to other prion diseases warrant continued vigilance. As scientists piece together the puzzle of CWD's impact on humans, the possibility of a dystopian reality remains a concern. Preventative measures and further research are essential to understand and mitigate any potential risks associated with chronic wasting disease.
