## TL;DR

Ceiling-mounted far-UVC fixtures can reduce surface contamination in clinics while being safe for people nearby.

## Contribution

The study shows real-world effectiveness of far-UVC in reducing bioburden in occupied clinical areas.

## Key findings

- Far-UVC fixtures reduced surface bioburden in clinical areas.
- The reduction occurred despite frequent contamination from routine use.
- Far-UVC is safe for continuous use in occupied spaces.

## Abstract

Contaminated surfaces in clinics pose a pathogen transmission risk. Far ultraviolet-C light (UVC), with a favorable safety profile for human exposure, has the potential for continuous pathogen inactivation in occupied clinical areas. This study demonstrated real-world bioburden reduction on surfaces, despite frequent contamination from routine use by staff and patients in clinics.
