Air-Treatment Systems for Controlling Hospital-Acquired Infections

This article examines the epidemiology and aerobiological pathways of airborne nosocomial infections and reviews air- and surface-disinfection technologies.

Hospital-acquired, or nosocomial, infections (Figure 1) have proven to be a persistent and sometimes tragic problem. If transmission by direct contact predominates, as many experts suggest, then surface-disinfection technologies should have a major impact in reducing-infection rates. But with more than a third of all nosocomial infections possibly involving airborne transmission at some point, the combination of surface and air disinfection should produce optimum result
