MAP: Chronic wasting disease in captive facilities and free-ranging populations

September 19, 2013 | 3:50 p.m. CDT
Chronic wasting disease, a neurological disease found mostly in the deer family, spread across North America beginning in 1967. Prior to 2000, the disease was confined to parts of Colorado and Wyoming. No treatment has been found for the fatal disease, and infected animal populations are exterminated to prevent additional transmission.
