The Emergence of Chronic Wasting Disease

The emergence of the ‘Zombie Deer’ disease, also known as chronic wasting disease (CWD), has sparked widespread concern in the United States. Recent cases, including one in Yellowstone National Park, have reignited fears among wildlife experts and the general public. First identified in the late 1960s, CWD has since made its way into the wild deer population and has spread to at least 31 states in the U.S. and several other countries, posing a persistent threat to wildlife. This prion disease affects various species such as deer, elk, reindeer, sika deer, and moose, and infected animals may take over a year to show symptoms, making prevention a critical focus. While there have been no reported cases of CWD infection in humans, recent studies raise concerns about the potential risk to certain non-human primates. Urgent research is underway to determine the potential risks to humans, emphasizing the need for preventive measures and heightened awareness. Hunters are advised to take specific precautions, and government agencies are actively involved in regulating and monitoring the spread of CWD.
