Scrapie is a deadly brain disease that affects sheep and goats. It cause damage to the brain and nervous system, with symptoms that include changes in behavior, such as nervousness, as well as trembling and loss of coordination. The disease is believed to be caused by abnormal prion proteins, which gather in the brain and spinal cord, leading to neurological damage. Scrapie is spread through contact with infected animals or their bodily fluids. It is not known to affect humans, but it can have significant economic impacts on affected livestock populations. While there is no cure for scrapie, efforts to control its spread include surveillance, quarantine, and selective breeding for resistance.
