NCT ID NCT05084898
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested whether far-UVC light, a safe type of ultraviolet light, can reduce respiratory infections like flu and COVID-19 in long-term care facilities. The trial involved 550 elderly residents who are at higher risk due to age and health conditions. The light was used as an extra cleaning method alongside usual hygiene practices.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
Far-UVC light (222 nm wavelength) as an additional disinfection method
What this could lead to
If effective, far-UVC light could become a simple, safe way to reduce the spread of flu and COVID-19 in nursing homes, protecting vulnerable elderly residents.
What could go wrong
This is a completed trial, but results are not yet widely confirmed. The study was relatively small (550 participants) and only in long-term care settings, so it may not apply to other environments.
