Ultraviolet (UV) light is a form of light that is invisible to the human eye. It occupies the portion of the electromagnetic spectrum between X-rays and visible light. The sun emits ultraviolet light; however, much of it is absorbed by the earth’s ozone layer.
Scientists have known for decades that broad-spectrum UV light, which has a wavelength of between 200 to 400 nanometers (nm), is highly effective at killing bacteria and viruses by destroying the molecular bonds that hold their DNA together. This conventional UV light is routinely used to decontaminate surgical equipment.
Unlike chemical approaches to water disinfection, UV provides rapid, effective inactivation of microorganisms through a physical process. When bacteria, viruses and protozoa are exposed to wavelengths of UV light, they are rendered incapable of reproducing and infecting. UV light has demonstrated efficiency against pathogenic organisms, including those responsible for cholera, polio, typhoid, hepatitis and other bacterial, viral and parasitic diseases.
A significant body of scientific research has proven UV light’s ability to inactivate an extensive list of pathogenic bacteria, viruses and protozoa. UV offers a key advantage over chlorine-based disinfection, due to its ability to inactivate protozoa.
UV light, specifically between 200-280nm[i] (UVC or the germicidal range), inactivates (aka, ‘kills’) at least two other coronaviruses that are near-relatives of the COVID-19 virus: 1) SARS-CoV-1[ii] and 2) MERS-CoV[iii] [iv] [v]. The effectiveness of UV light in practice depends on factors such the exposure time and the ability of the UV light to reach the viruses.
According to AFP fact check “Ultraviolet is able to kill COVID-19 if it is exposed to the concentrated UV ray in a certain amount of time and distance”. Most likely, it will be in the light bulb or lamp as the natural UV from the sun is not strong enough to kill it. The World Health Organization agrees.
