Short-sleeved shirts accumulate just as much bacteria as long-sleeved white coats

When it comes to infection control, short sleeves aren't any better than long ones. Doctors' long-sleeved white coats don't harbor more bacteria than short-sleeve shirts, according to a study published in the Journal of Hospital Medicine, Scientific American reports.
