Using UV Light To Reduce COVID-19 Transmissions

A London-led study by the Queen Mary University has shown that UV light tech can help reduce COVID-19 transmission. Although we’ve already heard about this, the research focused more on germicidal irradiation above people’s heads, since UV can be harmful to us if exposed to it for a prolonged period of time. It’s known as upper-room UVGI, but how did the researchers opt for this method to test?

Has it been done before?

On this strand of Coronavirus? No, but it has been tested on others. By analysing previously published material and running new tests, the COVID-19 particles subjected to this light were “inactivated”. This means that the light could be used on public transport and windowless rooms where ventilation is harder to come by.

Upper-room UVGI is already in use fighting against measles and tuberculosis amongst other viruses, but further research is needed to confirm it for indoor use in offices, bars and restaurants. In poorly ventilated areas, ceiling fans might be needed in order to get particles circulating, and then irradiated properly. This becomes even more apparent during winter when we can’t leave windows open.

Would you like to see this tested and used in Malta? Let us know in the comments!
