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.

Germicidal UV (GUV)* is an evidence-based,2 safe, and cost-efective way to protect people from exposure to TB and mitigate the risk of its transmission. Natural and mechanical ventilation are ideal ways to bring clean air into a space and prevent airborne transmission.

Objectives: To test the efficacy of upper room germicidal air disinfection with air mixing to reduce tuberculosis transmission under real hospital conditions, and to define the application parameters responsible as a basis for proposed new dosing guidelines.

UR GUV has often been used for IPC of pulmonary tuberculosis (TB). TB bacteria are spread through the air. To show its effectiveness as an intervention against TB, studies were done in South Africa and Peru, in active TB wards.

Germicidal ultraviolet (GUV) air disinfection (also referred to as Ultraviolet Germicidal Irradiation or “UVGI”), as a control method for the transmission of airborne pathogens, has been used for more than 80 years. In 1942, upper-room GUV (disin-fecting the room air by irradiating the air space above head

Mr. Vincent applies germicidal ultraviolet (GUV) disinfection technology and tools to control the transmission of tuberculosis and other infectious diseases both airborne and surface borne (fomite) or mix-mode, in high-risk settings.

Upper-room germicidal ultraviolet (GUV) systems are recommended to reduce M. tuberculosis transmission to health workers, persons attending health care facilities or other persons in settings with a high risk of transmission. (Conditional recommendation based on moderate certainty in the estimates of effects)

evidence base supporting the use of upper room germicidal ultraviolet systems (UR-GUV). For decades, UR-GUV has been a powerful tool for airborne infection control, and it has recently gained popularity as a possible measure to stop the spread of the SARS-CoV-2 virus in public spaces. The goals

2024年11月7日 · Germicidal UV Lamps are not only effective for the control of tuberculosis transmission, but also for other microbial disorders such as Influenza, Morbillivirus (causing measles), and aerosolized bioterror agents. Tuberculosis is an infectious disease that can be contracted by breathing air containing the tuberculosis bacterium.

Low-dose upper-room germici-dal ultraviolet-C (GUV 254 nm) is well suited for this because of the SARS-CoV-2 virus’ sensitivity to GUV inacti-vation and GUV’s relatively easy adaptability to many types of indoor spaces without respect to outside weather condi-tions.
