How is UV disinfection used today?
It’s been known for more than 100 years that UV light kills microorganisms quite effectively. That includes viruses similar to the one that causes COVID-19. It’s widely used in wastewater and drinking water treatment, and the industry is very well regulated based on decades of science and practice. The application of UV treatment in medical care is more recent, and that’s where a lot of the research effort is going on today. Often, it’s mentioned in the context of superbugs, which are pathogens that have become resistant to traditional antibiotics.
