A study at Leeds University (Comparison of UV C light and Chemicals for Disinfection of Surfaces in Hospital Isolation Units, Infection Control and Hospital Epidemiology, July 2006, Vol. 27, No.7) compared UV-C light and chemical disinfection in hospital isolation units.
They found that after a standard cleaning of these units, the additional use of UVC significantly reduced the numbers of colony-forming units.
Since Sterilray can be more than 1000 more effective in killing these microorganisms, then a general cleaning with Sterilray disinfection following will produce even better results.
This becomes particularly important since Sterilray is very effective in reducing MRSA, VRE, and C. difficle.
Other studies have shown that standard cleaning can miss up to 40% of the contaminated surfaces.
Following the standard procedure with a separate Sterilray operator to disinfect the same room will significantly reduce the possibility of missing this amount of surface.
