Researchers have found that the coronavirus is inactivated by sunlight as much as eight times faster in experiments than predicted by current theoretical modelling, providing a glimmer of hope in turning the tide on the pandemic.
UC Santa Barbara assistant professor of mechanical engineering Paolo Luzzatto-Fegiz conducted an analysis of 2020 studies exploring the effects of different forms of UV radiation on the SARS-CoV-2 and found a significant discrepancy.
As with all electromagnetic radiation, UV falls on a spectrum, with longer-wave UVA reacting differently with parts of DNA and RNA than other mid-range UVB waves contained in sunlight, which kill microbes and cause sunburn in humans.
Short-wave UVC radiation has previously been shown to deactivate viruses such as SARS-CoV-2, which is responsible for Covid-19, but this section of the UV spectrum is deflected away by the Earth’s ozone layer.
