A deadly and infectious condition know as ‘zombie deer disease’ is said to be spreading rapidly across the US – and humans could be next, an expert has warned. Chronic Wasting Disease (CWD) is currently plaguing deer, elk and moose across 24 states and two Canadian provinces. The disease attacks the brain, spinal chord and other tissues in the creature, before ultimately resulting in death. It also causes dramatic weight-loss, loss of coordination and bouts of hyper-aggression. ‘Since 2000, the area known to be affected by CWD in free-ranging animals has increased to at least 24 states, including states in the Midwest, Southwest, and limited areas on the East Coast,’ the CDC says.
