Methods of disinfecting non-critical surfaces in patient-care areas

Disinfecting non-critical surfaces in patient-care areas
Vaporized hydrogen peroxide		Disinfectants
Types	Virucidal efficacy	Hypochlorous acid (HOCl)	Other disinfectants
Non-condensing vaporized hydrogen peroxide (VHP) technology (Steris) and condensing search hydrogen peroxide vapour (HPV) technology (Bioquell)	Limited evidence is available for the virucidal activity of condensing HPV systems. Recently, several studies have demonstrated the in vitro activity of condensing HPV systems against individual viruses, including feline calicivirus (FCV), adenovirus, lactococcal bacteriophages6, and MS2 coliphage	Virucidal efficacy	Alkalis, oxidizing agents, alcohols, and aldehydes
		• Virucidal ability of solutions containing a high amount of HOCl is better than those containing HCl • Reduction of efficacy after spraying from a distance more than 30 cm • Minimum concentration should be more than 40 ppm for effective virucidal effect • The 100 and 200 ppm concentrated solutions inactivated more than 99.9% of AIV directly after spraying, while the 50 ppm concentration required at least 3 min of contact
