One in 2,000 people in the U.K. may carry an infectious prion protein that causes the deadly variant Creutzfeldt-Jakob disease, the human form of mad cow disease, according to a study in the British Medical Journal. After previous studies came to varied conclusions about how many people may have the abnormal protein, a U.K. panel ordered a more comprehensive study by researchers at University College London, who found 16 positive cases in 32,441, which translates to a rate of 1 in 2,000.
