Abstract

Hospital-associated infections (HAIs) are a major burden in healthcare systems. In this study, UVC LEDs emitting radiation from 260 to 270 nm were evaluated for effectiveness in reducing methicillin-resistant (MRSA), vancomycin-resistant and . The array has four WD LEDs, each with 70 mW placed at 7 cm from test organisms. With 11.76 mJ cm, the study obtained 99.99% reduction (log reduction factor of 4) against MRSA and VRE. For , 9 mJ cm obtained 99.999% reduction (log reduction factor of 5). These results present scientific evidence on how effective UVC LEDs can be used in the fight against HAIs.
