Germicidal Ultraviolet Light

For years, germicidal ultraviolet light (GUV) has been a powerful tool for the prevention of tuberculosis. It is a cost-effective intervention that is safe and supported by a breadth of evidence that has accumulated over decades. Like tuberculosis, the virus responsible for the COVID-19 pandemic is also transmitted through the air in droplets from individuals shedding the virus. The goal is to use GUV for COVID-19 in much the same way as it has been used for TB, installing lights in places with poor ventilation in order to circulate and sanitize the air people breath. All of this is done with the utmost concern for safety and the intent to make public spaces safe for everyone. In order to better understand how GUV lighting is used for disease prevention, please check out some of the resources below.
