A negative pressure isolation ward prevents the outflow of airborne microorganisms from inside the ward, minimizing the spread of airborne contamination causing respiratory infection. In response to recent outbreaks of severe acute respiratory syndrome (SARS) and Middle East respiratory syndrome (MERS), Korea has increased the number of these facilities. However, airborne contaminants that flow into the ward from adjacent areas may cause secondary harm to patients. In this study, the…

Effect of Ultraviolet Germicidal Lamps on Airborne Microorganisms in an Outpatient Waiting Room
Abstract The effectiveness of 254-nm ultraviolet radiation for inactivating airborne microorganisms (and thereby reducing the spread of respiratory infections such as tuberculosis) was evaluated by
The characterization of upper-room ultraviolet germicidal irradiation in inactivating airborne microorganisms.
TLDR
The regression results indicated that the number of UV fixtures, use of mixing fan, and air exchange rate significantly affected UV effectiveness and the strain difference (S. marcescens vs. BCG) appeared less important in UV effectiveness.
Effects of ultraviolet germicidal irradiation and swirling motion on airborne Staphylococcus aureus, Pseudomonas aeruginosa and Legionella pneumophila under various relative humidities.
TLDR
The studied UV device, with a combination of swirling motion and UVGI, is effective to inactivate airborne S. aureus, P. aeruginosa, and L. pneumophila and has the potential to be installed indoors where people are simultaneously present, for example, hospital wards and nursing homes, to prevent the humans from acquiring infectious diseases.
The importance of bioaerosols in hospital infections and the potential for control using germicidal ultraviolet irradiation
TLDR
Research carried out at the University of Leeds and elsewhere has shown that a whole range of potentially pathogenic bacterial species are susceptible to UV, and the market for new disinfection technologies is great.
