Does UVC Prevent The Spread Of Covid-19?

May. 14, 2021

The International Ultraviolet Association (IUVA) believes, based on current disinfection data and empirical evidence, that UV disinfection technology can play a role in a multi-barrier approach to reduce the spread of the virus that causes COVID-19, SARS-CoV-2.


UV is a known air, water and surface disinfectant that, if used correctly, can help mitigate the risk of infection following contact with the COVID-19 virus. " UVC disinfection equipment manufacturer will share with you.


It is important to note that the terms " UVC", " UV disinfection" and " UV" as used here and in the scientific, medical and technical literature, refer particularly importantly to the germicidal range of UVC light energy (200-280nm light). This is different from UVA and UVB as used in tanning beds or tanning.

Facts about UV and COVID-19

Can UVC help prevent the spread of COVID-19 by reducing pollution?

Based on the available evidence, we believe so. The reasons are as follows.


UVC lamps have been widely used to disinfect drinking water, wastewater, air, pharmaceuticals and surfaces against a full suite of human pathogens (using Fluence UV Dose required, subject to review of IUVA) for over 40 years. To date, all tested bacteria and viruses (including other coronaviruses for hundreds of years) have responded to UV disinfection. Some organisms are more susceptible to UVC disinfection than others, but so far all tested microorganisms can respond at the appropriate dose.

UVC disinfection is often used in a multi-barrier manner with other technologies to ensure that pathogens not "killed" by one method (e.g., filtration or cleaning) are inactivated by another method (UVC). In this way, UVC can now be installed in clinical or other settings to augment existing processes or enhance existing protocols to avoid excessive demand on those protocols due to pandemics.


COVID-19 infection can be caused by contact with contaminated surfaces and then contact with facial areas (less common than person-to-person, but still a problem). Minimizing the risk is key because COVID-19 virus can survive on plastic and steel surfaces for up to 3 days. Routine cleaning and disinfection may leave some residual contaminants, which can be treated by UVC, suggesting the careful use of multiple disinfection methods. UVC has been shown to achieve a high degree of inactivation of the closely related COVID-19 virus (i.e., SARS-CoV-1, when suspended in liquid and tested with sufficient doses of 254 nm UV). Similar results can be obtained in the treatment of SARS-CoV-2, a virus of COVID-19. However, the key is to use UVC in such a way that any residual virus on these surfaces can be effectively infected.


The germicidal effectiveness of UVC is influenced by the absorption characteristics of UVC by the suspension, the surface on which the organism is located, or the aerosol; by the type or spectrum of action of the microorganism; and by various design and operational factors that affect the dose of UVC delivered to the microorganism.


By applying UVC light to many easily exposed surfaces as a secondary barrier to cleaning, especially in emergency conditions, the total pathogen load can be greatly reduced. Illuminating relevant surfaces (e.g., air and surfaces around/in rooms and personal protective equipment) with UVC light would be relatively simple.
