The prion disease that is known to affect the deer and elk is known as chronic wasting disease and it is called so as the affected animal undergoes severe weight loss (wasting) along with other neurological symptoms.
It is a chronic disease as it takes years for the symptoms to manifest themselves in the infected animal.
