New study explores potential cross-species spread of chronic wasting disease

A new study found that chronic wasting disease can sometimes spread silently, with infectious prions present even in animals that show no symptoms. While there is no confirmed human risk, researchers say the disease’s ability to evolve and spread across species warrants close attention.

• Share: Facebook Twitter Pinterest LinkedIN Email FULL STORY Scientists uncovered a hidden side of chronic wasting disease: infectious prions may spread unnoticed, raising new questions as the fatal wildlife disease continues to expand.
• However, a new study from researchers at the University of Calgary and their international collaborators examined whether the disease could potentially move beyond cervid (hooved, plant-eating) animals and infect other species.

What the source reports

There has never been a confirmed case of CWD in people. Even so, scientists say the new findings highlight the importance of continued monitoring and research as the disease continues to spread into new areas. CWD is a fatal neurological disease caused by infectious proteins called prions.

Why it matters

It is becoming increasingly widespread across North America, including expanding regions of Alberta.
