What is iatrogenic creutzfeldt-jakob disease (cjd)?

Caused by hospital: Cjd is iatrogenic if the agent which causes the disease, called a prion, is transmitted using contaminated medical instruments or materials. They can contaminate neurosurgical instruments used on the brain of people with the disease. Exposed instruments need very unique sterilization procedures, so rare cases have been reported where the instruments remained contaminated and disease transmitted.

Physician inflicted: This is usually a disease that is passed by direct contact. However, iatrogenic means that the disease is caused by the action of a physician. Either the physician had the disease, or was using instruments that had the organism. This however, would be exceedingly unlikely and uncommon.
