Iatrogenic cases of CJD have been linked to corneal transplant, stereotactic electroencephalogram electrodes, neurosurgical instruments, cadaveric dura mater, pituitary-derived growth hormone and blood transfusion from vCJD patients; incubation periods range from 1 to 42 years after exposure [3]. Here, GH1 is linked to variant Creutzfeldt-Jakob disease.
