Clinical Signs
Most cases of CWD occur in adult animals. The disease is progressive and always fatal. The most obvious and consistent clinical sign of CWD is weight loss over time. Behavioral changes also occur in the majority of cases, including decreased interactions with other animals, listlessness, lowering of the head, blank facial expression, repetitive walking in set patterns, and a smell like meat starting to rot. In elk, behavioral changes may also include hyperexcitability and nervousness. Affected animals continue to eat grain but may show decreased interest in hay. Excessive salivation and grinding of the teeth also are observed. Most deer show increased drinking and urination.

Famous quotes containing the word signs:
“[Christianity] endeavors equally to establish these two things: that God has set up in the Church visible signs to make himself known to those who should seek him sincerely, and that he has nevertheless so disguised them that he will only be perceived by those who seek him with all their heart.”
—Blaise Pascal (1623–1662)
