Scent machines used in war against hospital superbug

Originally designed to mask unpleasant odors on hospital wards, scent machines in a U.K. hospital are also being tested for their ability to prevent infection. The machine disperses a special recipe of particular essential oils that attack MRSA, a hospital-borne superbug that kills up to 5,000 U.K. hospital patients each year and countless others throughout the world. In a 9-month trial of one essential oil-dispersing machine on a ward, infection on the ward was significantly reduced and airborne bacterial counts were reduced by 90%.
