Study shows zombie deer disease prions can infect primate brains

A new study suggests the "zombie deer disease" prion can infect primate brains, raising concerns about human risk. Researchers found evidence that cervid prions can enter primate brains and cause changes, challenging previous assumptions of near-complete protection for primates. While not proving direct human transmission, the findings highlight the need for caution and further research into the potential zoonotic threat of CWD.
