Summary

This study tested whether special UV light devices placed in common areas of nursing homes can reduce the number of severe respiratory infections (like pneumonia or COVID-19) in elderly residents. Over 1,600 residents in 12 French nursing homes took part. The devices were either active or deactivated (as a placebo) to see if they made a difference. Results are expected by mid-2026.

What this could lead to: If it works, this could provide a simple, non-drug way to prevent serious respiratory infections in nursing homes, potentially saving lives and reducing hospitalizations.
What could go wrong: This is a completed trial, but results are not yet published. The devices may not significantly reduce infections, and effectiveness could vary by setting or compliance.
