Can CJD lay dormant?

Humans contract vCJD after eating the meat of a cow with BSE. Caused by misformed proteins called prions that affect the brain, in both cows and humans the disease can be dormant for a long time before symptoms begin to show.

Has anyone survived CJD?

Most people with CJD die within 6 to 12 months after symptoms appear. About 10 to 20% of people survive for 2 years or more. People with vCJD usually survive for about 18 months.

What triggers CJD?

Creutzfeldt-Jakob disease (CJD) is caused by an abnormal infectious protein in the brain called a prion. Proteins are molecules made up of amino acids that help the cells in our body function. They begin as a string of amino acids that then fold themselves into a 3-dimensional shape.

Is there a test for CJD?

The only way to confirm a diagnosis of CJD is to examine the brain tissue by carrying out a brain biopsy or, more commonly, after death in a post-mortem examination of the brain.

Can you get CJD from chicken?
