What is Chronic Wasting Disease (CWD) and Where has it been found

Description 

Chronic Wasting Disease (CWD) is a contagious neurological disease affecting deer and elk. It causes a characteristic spongy degeneration of the brains of infected animals resulting in emaciation, abnormal behavior, loss of bodily functions and death. The infectious agents are consider to be neither bacteria or virus but rather are thought to be prions. Prions are considered to be infectious proteins with out associated nucleic acids.
