Having just last summer/fall spent three months with a relative undergoing four surgery's - three because of repeat infections, including a few days in an isolation unit because they contracted VRE, during one of the operations, MRSA and VRE infections during surgeries are big worry in hospitals.
However, there seems to be some new research in prevention and control in connection with using brass and copper instead of stainless steel. Apparently the MRSA virus and some other nasty bugs, are killed within a few hours when in contact with brass or copper. The theory is that if the hospitals switched to brass door knobs and such, there'd be less risk of spreading those bugs ????
