How does vCJD differ from Creutzfeldt Jakob disease ( CJD )?
How does vCJD differ from Creutzfeldt-Jakob disease (CJD)? Both variant Creutzfeldt-Jakob disease (vCJD) and CJD cause progressive degeneration of the brain leading to death. However, the variant form—never seen before 1994—usually affects persons much younger than other forms of CJD.
Can a red blood cell recipient get vCJD?
Three of the red blood cell recipients developed typical vCJD and died from the disease. A fourth died of an unrelated illness but had evidence of infection.

How long does it take to die from vCJD?
The disease always progresses to death. Disease duration is 14 months on average. vCJD tends to affect younger individuals, with an average age of onset of around 28 years, compared to sporadic CJD, which tends to affect middle-aged and elderly individuals. The definite diagnosis of vCJD requires post-mortem examination of brain tissue.
