Far-UVC Light for Respiratory Infections

(PRiVII Trial)

This trial tests whether a special type of ultraviolet light, called far-UVC, can reduce the spread of viruses causing respiratory infections, such as the flu and COVID-19, in long-term care facilities. It focuses on elderly residents who may struggle with standard infection control methods due to memory issues and shared spaces. The trial compares far-UVC light as a disinfectant with a regular fluorescent light that lacks disinfectant properties. Residents in long-term care who agree to data collection might be suitable for this study. As an unphased trial, it offers participants the chance to contribute to innovative research that could improve infection control in vulnerable populations.

The trial information does not specify whether you need to stop taking your current medications.

Research has shown that far-UVC light is both effective and safe for humans. Studies have found that far-UVC light, particularly at 222 nm, can kill germs without damaging human skin or eyes. This is crucial because regular ultraviolet light can be harmful if used directly. Tests in indoor places like hospitals have confirmed that far-UVC light remains safe even with long-term exposure. It effectively kills airborne viruses, helping to reduce infection spread. To date, no significant harmful effects have been reported with far-UVC light, making it a promising option for additional disinfection.¹²³⁴⁵

Researchers are excited about the potential of Far-UVC light for respiratory infections because it offers a unique method of disinfection. Unlike traditional chemical disinfectants or antibiotics, Far-UVC light can inactivate viruses and bacteria in the air without harming human skin or eyes, thanks to its specific wavelength. This means it could provide continuous, safe, and effective disinfection in public spaces, potentially reducing the spread of infections more efficiently than current methods.

Research has shown that Far-UVC light can kill viruses in the air and on surfaces. Studies have found that Far-UVC light, with a wavelength of 222 nm, deactivates viruses like those causing COVID-19 and the flu. This light damages the virus's genetic material, preventing it from spreading. It is as effective as other germ-killing lights but safer for people. In this trial, participants will be exposed to Far-UVC light as an additional disinfection method, which could help reduce viral infections, especially in long-term care facilities.⁶⁷⁸⁹¹⁰
