Experts are suggesting a new dress code for doctors and nurses in hospitals.

The main concern is that lab coats, ties, watches, rings and shoes worn by health workers contain too many germs that could make patients sick. Up to this point, there's nothing to show that such outer wear rapidly spreads germs. However, the Society for Healthcare Epidemiology of America says cleaner outfits are a sensible approach. Still, some experts believe more studies are required to determine if it helps reduce infections.
