Chronic Wasting Disease
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 considered to be neither bacteria or virus but rather are thought to be prions. Prions are considered to be infectious proteins without associated nucleic acids.
