Highlights
- •We sampled 38 hospital rooms for aerobic bacteria on surfaces.
- •Utilized PX-UV as a disinfectant tool without any manual cleaning.
- •Collected aerobic bacteria samples before and after PX-UV disinfection.
- •Found a significant decrease in aerobic bacteria counts after PX-UV usage.
