Creutzfeldt-Jakob disease (CJD) is a rare, rapidly progressive, and fatal neurodegenerative disorder. It is caused by **prions**, which are abnormally folded proteins that induce normal proteins in the brain to misfold. CJD primarily affects older adults (sporadic form) worldwide, leading to rapid mental and physical deterioration. Track Creutzfeldt-Jakob disease activity and outbreaks specific to Tennessee.

Creutzfeldt-Jakob disease was first described in the early 1920s by German neurologists Hans Gerhard Creutzfeldt and Alfons Maria Jakob. Its significance grew with the understanding of transmissible spongiform encephalopathies (TSEs), particularly the link between **variant CJD** and bovine spongiform encephalopathy (BSE) in the 1990s, highlighting the unique nature of prion diseases.
CJD is not contagious through casual contact. Most cases are **sporadic**, meaning they occur spontaneously without a clear cause. Transmission can also occur through medical procedures (**iatrogenic CJD**) involving contaminated brain tissue or instruments, or through inheritance (**familial CJD**); **variant CJD (vCJD)** is acquired by consuming contaminated beef products.
Contagious Period: Varies by disease
