A Fatal Deer Disease May Be Spreading in Ways No One Expected
Scientists found that chronic wasting disease may spread silently between species, revealing a hidden challenge in the fight against the fatal wildlife disease. Chronic wasting disease (CWD) is best known as a disease affecting deer, elk, and other cervid (hooved, plant-eating) animals. Now, researchers at the University of Calgary and their international collaborators have taken [...]
Science Advances Study: Deer With No CWD Symptoms Still Carry Infectious Prions — and They Can Spread to Other Species
Science Advances June 16, 2026: CWD prions detected in asymptomatic deer tissues can still transmit to other species. 36 U.S. states affected. What hunters need to know.
A recent study has revealed that chronic wasting disease (CWD), which primarily affects deer, can be silently transmitted between species, raising concerns about its spread and control. The research, conducted by scientists at the University of Calgary, highlights the ability of infectious prions to spread without animals showing visible symptoms. Silent transmission between species The research demonstrated that animals infected with CWD can ca…
CWD Research, Insights Shared At Deer Associates Gathering
This is the sort of news that ought to keep every deer manager awake at night. Chronic Wasting Disease isn't behaving like a bad season, a drought, or a predator problem—it behaves more like a slow-moving wildfire, spreading quietly for years before folks realize how much damage has already been done. In parts of Arkansas, researchers documented infection rates approaching 50 percent and deer populations declining by roughly 17 percent annually,…
