Prayer #171: For the Potential Use of Far-UVC Light to Inhibit the Spread of COVID-19
A recent study has demonstrated that ultraviolet light UVC) on the far end of the wavelength spectrum at 222 nanometers is more than 99.9% effective in killing COVID-19 present in airborne droplets. The study, published in Scientific Reports, was performed by the Vagelos College of Physicians at the Columbia University Irving Medical Center.
The conventional UVC light that has been long used as a germicidal is at 254 nm and can be used to disinfect unoccupied spaces such as empty hospital rooms or subway cars, but its use in occupied spaces is prohibited because it can penetrate the skin and cause damage. The UVC at 222 nanometers, however, does not penetrate the outer dead layer of skin nor the tear layer of the eye and thus is safe to use in occupied areas.
The researchers of this study indicated that 222-nanometer UVC light kills 90% of airborne viruses in 8 minutes, 95% in 11 minutes, 99% in 16 minutes, and 99.9% in 25 minutes. "Based on our results," stated Dr. David Brenner, one of the authors of the study, "continuous airborne infection with far-UVC light at the current regulatory limit could greatly reduce the level of airborne virus in indoor environments occupied by people. Because it's safe to use in occupied spaces like hospitals, buses, trains, train stations, schools, restaurants, offices, theaters, gyms, and anywhere that people gather indoors, far-UVC light could be used in combination with other measures, like wearing face masks and washing hands, to limit the transmission of SARS-CoV-2 and other viruses."
Pray for wisdom regarding the potential use of far-UVC to eradicate COVID-19 from indoor spaces. This seems most promising. Pray that proper attention to the results of this study would be given by health officials and civic leaders.
