Recent studies suggest that UV light may help reduce COVID-19 transmission indoors “We have been able to demonstrate that UV-C susceptibility constant Z, for SARS-CoV-2 is likely to be similar to that exhibited by SARSCoV-1 and MERS-CoV viruses. Furthermore, we have found evidence suggesting that SARS-CoV-2 when suspended in air is reasonably easy to inactivate using UV light at 254nm. As such, this suggests that upper-room UVGI may have great potential as an intervention to inhibit the transmission of COVID-19 in buildings, especially in situations where achieving high ventilation rates might otherwise be impractical.” Upper-room ultraviolet air disinfection might help to reduce COVID-19 transmission in buildings.
