Arizona: Use of a Portable Air Disinfecting System to Remove Seeded Coliphage in Hospital Rooms

Healthcare-associated infections are a major problem worldwide, and the airborne route is believed to be a contributory source of secondary healthcare-associated infections. A study by researchers at the University of Arizona Mel and Enid Zuckerman College of Public Health examined the efficacy of a portable air disinfecting system to remove seeded coliphage virus from the air in hospitals rooms. The study was published in the American Journal of Infection Control.

The study found aerosolized coliphage concentrations were not statistically different between treatment and no treatment measurements. Differences in measured virus levels between rooms were related to air exchange rates. Portable air filtration may provide the most benefit in low air exchange rate environments.

Future research should focus on additional investigations in the patient rooms that incorporate fomite and air testing alongside portable air filtration devices.
