A concerning and fatal illness called Chronic Wasting Disease (CWD) has been detected in deer, elk, and moose across 32 states in the United States and four provinces in Canada, according to a recent report from the National Wildlife Health Center. The disease, often referred to as "zombie deer disease," causes severe damage to the brain and nervous system, leading to distressing symptoms and a steady decline in the affected animals' health. While the name may evoke images of aggressive and undead creatures, experts clarify that this misrepresents the true nature of the disease.

The Texas Parks and Wildlife Department describes the symptoms of CWD, including stumbling, excessive drooling, head lowering, blank stares, listlessness, and lack of fear towards humans. Affected animals gradually become emaciated and wasted over a period of a year or more, as the abnormal protein particles, known as prions, accumulate in the brain, creating sponge-like holes and impairing normal functioning. Dr. Krysten Schuler, a wildlife disease ecologist with Cornell University's College of Veterinary Medicine, emphasizes the tragedy of the disease, stating that these animals deserve empathy and respect for the challenges they face.

Recent cases of CWD have been reported in various regions over the past two months. Notably, Kentucky reported its first-ever occurrence of the disease, followed by detections in Yellowstone National Park and Coleman County, Texas. The expanding reach of CWD is a cause for concern, as it continues to pose a threat to wildlife populations in North America.

While there have been no reported cases of humans contracting CWD, the Centers for Disease Control and Prevention (CDC) acknowledges the potential risk to humans. Research suggests that monkeys can become infected if they consume meat from CWD-infected animals or come into contact with contaminated brain or body fluids. A scientific study published in the journal Acta Neuropathologica in 2022 confirms that there is a genuine risk of transmission to humans.

Drawing parallels to zoonotic diseases like COVID-19 and the transmission of variant Creutzfeldt-Jakob disease from animals to humans in the case of mad cow disease, Dr. Schuler emphasizes the need for caution. Health officials advise against consuming meat from animals infected with CWD, and the World Health Organization stresses the importance of preventing the entry of prion disease agents into the human food system.

The prevalence of Chronic Wasting Disease across multiple states and provinces serves as a somber reminder of the escalating threat to wildlife populations and the potential risks to humans. Efforts to understand and contain the disease are crucial to ensure the well-being of both animal and human communities.
