While this is currently focused on infections spread within the confines of hospitals (which actually IS a major problem!), there's no doubt that it will eventually become a widely-used tool for many other purposes. http://www.msnbc.msn.com/id/48771372/ns/health/#.UDb9NaFlSDk
Cool! I wonder if the air conditioning could have spread this microbe because the AC goes everywhere throughout the hospital in the ductworks. All ductworks lead to every room in every hospital with no exception so that could be the way the microbe travelel. They would need to install filters, if they already don't have them, in each ICU room to kill any microbe that gets sucked up into it.
