Is the growing use of hand sanitizers changing the normal ecology of our hands, making it easier for the MRSA bacteria to grow?

Probably not. MRSA, or methicillin-resistant staphylococcus aureus, normally lives in the nose and throat, the armpits and the perineum (the area near the anus), said Dr. J. Owen Hendley, professor of pediatric infectious diseases at the University of Virginia School of Medicine. It’s not commonly carried on the hands.
