Abstract:
The bovine spongiform encephalopathy (BSE) epidemic in cows, and the recent BSE-linked human infections, present new public health problems. More rigorous measures are needed to prevent additional transmissions. Tissue from established but undiagnosed human infections can contaminate medical supplies and instruments. We tested guanidine thiocyanate (GdnSCN) solutions and found them to be highly effective in disrupting the infectious agent, even in very complex tissues such as whole brain. It may be prudent now to use this reagent routinely in surgical and other relevant settings.

Cleaning, Sterilization, and Disinfection
Cleaning
The cleaning process usually involves using water with detergents or enzymatic cleaner and removing foreign material from objects and surfaces, including organic material such as body fluids or inorganic material like soil. Cleaning is performed before high-level disinfection and sterilization because foreign materials on the cover of the devices interfere with process...
Transmission-based Precautions II: Airborne and Protective Environment
Airborne precautions:
Use airborne precautions when treating patients known or suspected to have diseases that spread through the air—for example, tuberculosis or measles. These organisms are present in smaller droplets expelled by an infected person and...
Transmission-based Precautions I: Contact, Enteric, and Droplets
Contact Precautions:
Contact precautions are the measures taken to prevent the transmission of infectious agents, especially epidemiologically important microorganisms such as MRSA or influenza, primarily transmitted through direct or indirect contact with an...
