A case of variant Creutzfeldt-Jakob disease (vCJD) has recently been diagnosed in a patient in the United Kingdom (UK), who received a blood transfusion from a donor who later developed vCJD. This is the fourth case of probable transfusion transmission of vCJD infection in the UK. Three of the four recipients developed symptoms of vCJD.
