Just figure out that sick people come into the hospital, spread their germs, have visitors/nurse/doctors that touch them, touch door handles, pens, anything, and you have an atmosphere to spread germs. I believe everyone who enters a hosspital room should wash their hands or at least use the sanitizer on the wall. This should include visitors--and they certainly should do it before they leave. I usually shudder when I see small children in the hopital--children who put their hands on everything, and then in their mouths. Most of the nurses I know do not even wear their nurse's shoes home....
