Germ cops help hospitals prevent infection, death

This is no ordinary intensive care unit: Every doctor, nurse, friend or loved one must cover their clothes with a bright yellow gown and don purple gloves before entering a patient's room so some scary germs don't hitch a ride in or out.

It's part of the University of Maryland Medical Center's crackdown on hospital-spread infections, and Michael Anne Preas patrols the ICU like a cop on the beat to help keep bacteria in check

You forgot your gloves, Preas leans in to tell a doctor-in-training who's about to examine a man with a breathing tube. Startled, the resident immediately washes his hands and grabs a pair.
