Walk around near a hospital, and you'll see healthcare workers out and about, wearing their scrubs. It's the colorful, pajama-like uniform donned by anyone from hospital cafeteria employees to nurses and surgeons. Scrubs are on the move, in coffee shops, restaurants, on the subway - not exactly a fashion statement, but some experts are concerned that it also poses a health risk - since germs can travel in and out of hospitals on these uniforms. "You're really not supposed to wear scrubs outside of the hospital," explained one employee from a Philadelphia hospital who asked to remain unnamed. He added that he'd never been questioned by his employers about wearing scrubs outside.
