[Creutzfeldt Jakob disease. Recommended precautions for patient management and diagnostic procedures (author's transl)].

The virus of Creutzfeldt Jakob disease differs from conventional viruses in its extraordinary resistance to commonly used physical and chemical methods of decontamination. Autoclaving the virus for 1 hour at 121 degrees C and 2 atmospheres pressure is the most certain means for achieving total inactivation. Exposure to 5 p. 100 hypochlorite for several hours can also totally inactivate the virus, and exposure to phenol or potassium permanganate is probably effective, but as yet insufficiently tested.
