Chronic wasting disease spreads across 36 U.S. states

Chronic wasting disease (CWD), a fatal illness affecting deer, elk, and moose, is spreading across the United States. This disease is infectious and always fatal. Currently, it has been found in 36 states and in parts of Canada and Scandinavia. Scientists warn that it poses a serious threat to wildlife and potentially to human health. CWD’s symptoms include extreme weight loss, drooling, and disorientation. It has been nicknamed “zombie deer disease” in the media, a term many scientists find misleading. They argue it downplays the seriousness of the issue. "It trivializes what we’re facing," said epidemiologist Michael Osterholm. Experts emphasize that there has yet to be a documented case of human infection, but they are worried about the risks. A recent report from a panel of experts called the situation a potential national and global crisis. They fear that humans could become infected through consumption of contaminated game meat. Each year, tens of thousands of people eat venison, unknowingly including potentially infected meat. The Centers for Disease Control and Prevention advise testing deer from infected areas, but many hunters do not follow this guidance. CWD is caused by prions, which are resistant to typical methods of destruction and can contaminate environments for years. This raises concerns over the disposal of infected animal carcasses, potentially creating toxic sites for future wildlife. Conservationist Lloyd Dorsey has voiced worries about the effect of feedgrounds, where deer congregate and disease spreads. The disease threatens the stability of deer and elk populations, important for hunting traditions. A study in Wisconsin found that infected animals die at rates exceeding natural reproduction, risking population collapse. Predators that could help control sick animals are being reduced by state policies. Experts warn against ignoring scientific advice regarding wildlife management. The decisions made now could lead to serious consequences in the future. They call for improved land management to help create environments where wildlife can thrive without unnatural feeding practices, thereby reducing the chances of disease spread.
