Ultraviolet light can stop coronavirus

March 3, 2020

Coronavirus can be dramatically curtailed by using existing ultraviolet air-cleaning systems already used in some homes.

Ultraviolet instantly kills virus and bacteria, same as sunlight does. These easy, inexpensive systems could be installed in confined air systems to kill virus, like on airplanes, ships, stores, theaters, schools, restaurants, and gathering places with existing air circulation systems. These ultraviolet systems are not expensive.  The technology is already there and being used.

Channeled (duct) air flows over and around a long tube light, looks like an old-fashioned fluorescent bulb, that emits ultraviolet, killing nearly all the pathogens, most bacterial and all viral. It is used in some homes and on the space station and in spaceships.

If aIl states and governments make it mandatory in confined spaces, just think how much less vulnerable the future will be to rapid spread of virus.  How many people get on a plane then get a cold afterwards? Colds are viruses. Ultraviolet light  treatment of air flowing over the light works.

Such systems improve health of all in private homes.  Building codes could mandate the use of these fabulous air purifiers.

This won’t eliminate coronavirus, but once such systems are universally used, all of us will be healthier. Pandemics will not be able to spread so fast and capriciously. Dangerous viruses will have a hard time infecting any but close contacts, rather than everybody confined with one sick person.

Let me say, I am not an expert and have no connection of any kind to any company or business involved in that industry, just an ordinary observer with a science and life sciences education.  Sometimes solutions to problems are conspicuously staring us in the face.
