You're right that young people are investigated, and we don't see broad infection. I was thinking of causes for geriatric CJD, rather than vCJD. I'm skeptical of claims that geriatric declines are fully investigated. But the UK spike from contaminated food was very clear, and we don't see anything similar. Unless there's some low-level exposure the body can resist and a weakening blood-brain barrier/stroke/etc allows infection. But that's just speculation. Cheers.
