A study of 32,000 human appendix samples from 41 hospitals in the UK indicates that 1 in 2,000 British people may be carrying the abnormal prions associated with variant CJD (the human form of “mad cow” disease). It is uncertain whether people carrying the vCJD protein will develop any symptoms of rapid-onset dementia and neurodegeneration, or within which timescale.
