More doctors and nurses are entering patient exam rooms after slathering alcohol based sanitizer all over their hands rather than lathering up with soap and water. It's effective and user friendly. A study at the University of Nebraska shows after taking bacteria samples from those doctor and nurses.
Their hands were actually cleaner, but researchers were stumped that the infection rate among patients did not improve after exposure to the cleaner hands. Turns out infection still spread because of bacteria that was harboring under long fingernails and wedding rings.
