The infections were reported by Arkansas, Wisconsin, and Manitoba, Canada.
Listen to a recording of our Dec 3, 2025, webinar on vertical CWD transmission. Experts discussed the implications of vertical transmission for free-ranging white-tailed deer herds, and Cory Anderson, PhD, MPH, of CIDRAP's CWD team, moderated a Q&A session after the discussion.
The report provides useful guidance to professionals at human, animal, and wildlife health agencies; academic researchers; and medical practitioners who will be tasked with responding to any human or non-cervid animal chronic wasting disease spillover.

For the first time, chronic wasting disease has been detected in white-tailed deer in Manitoba—previous detections were in mule deer.
Testing done on samples from about 5,000 deer harvested in last year's hunting seasons in Iowa revealed that 84 deer were positive for CWD.
In North Carolina, officials confirm the first case detected outside of the state's surveillance area.
Trained dogs correctly identified CWD in 8 of 11 CWD-positive samples and had an average false-positive rate of 13%.
Earlier this month, officials confirmed CWD in Sheboygan County, and in January CWD was detected for the first time in Waupaca County.
The shortage is leading to delays in the testing of deer samples submitted by hunters.
The deer was a 2-year-old doe harvested by a hunter in the northwestern part of the county.
A buck brought to a taxidermist represents the first CWD case in Fairfax County, Virginia.
Researchers describe a CWD strain from a moose in Finland that's distinct not only from CWD prions in North America but also from those in neighboring Norway.
States and tribal wildlife agencies, which have struggled to contain the spread of chronic wasting disease, could then apply for funding for mitigation strategies such as testing.
