Brass Doorknobs to Prevent Infection
Copper (as well as silver) has prophyalactic anti-bacterial properties. Interestingly, copper and it's allows will curtail the highly contagious Methicillin-resistant Staphyloccus aureus, also known as MRSA. Changing building codes to make all bedrails. elevator buttons and doorknobs of copper alloy would be a great step towards eliminating in-hospital transmission. Copper on a food preparation surface will instantly kill all traces of e-coli.  The mechanism by which copper and it's alloys kill depend on Ions from copper which penetrate the cell walls of microbes disrupting their ability to propagate. Copper window screens eliminate bacterial. Water carried in copper pipes does not develop slime or bacterial growths, while this is not true for PVC. Both silver and copper (and the allows) should be polished and then rinsed (to remove any oil from the cleaning agent) for optimal anti-bacterial action. It makes a lot of sense to provide brass doorknobs is caring for an immune-comprised patient.

Alloys, not "allows". I wish we had a way to correct spelling in posts.
