UV light is an efficient way to disable the COVID-19 that causes the SARS-CoV-2 virus and to reduce transmission



The researchers found that radical social distancing was effective with the closure of public spaces, but that the economic and social costs would not be sustainable in the medium term.

The use of ultraviolet (UV) light to inactivate the SARS-CoV-2 virus, according to a study, can be an efficient, easy-to-use and economically cost-effective method for reducing indoor COVID-19 transmission.

The study, published in the journal ACS Nanoanalyzed the currently available UV-C sources such as fluorescent lamps, microcavity plasmas and LEDs.

It has been found that irradiation of this type of light in building ventilation systems and in shared interiors when not in use can quickly and efficiently deactivate SARS-CoV-2 viruses in the air and on the surface that cause COVID-19 .

The researchers said a global investment of several billion dollars in UV-C sources could protect indoor workers worldwide.

The researchers, including those of the CFO – the Institute for Photonic Sciences in Spain, also looked at costs and investments in the use of such technologies.

They said that a global investment of several billion dollars in UV-C sources could protect indoor workers worldwide.

A long series of studies suggest that indoor virus transmission has a much higher transmission rate than outdoors, the researchers found.

Filters and chemicals were presented as possible solutions to minimize this problem.

Although these are efficient solutions to reduce the concentration of contaminated particles and droplets through ventilation systems, the researchers believe that installing them can be costly and time-consuming.

In addition, chemicals such as ozone are very effective for virus disinfection, but if misused, they are harmful to humans, they are sad.

An international team of experts from the fields of virology, immunology, aerosols, architecture and physics investigated the possible methods for preventing the spread of SARS-CoV-2 indoors.

“We advocate the widespread use of UV-C light as a short-term, easy-to-use, and affordable method to limit virus spread in the current SARS-CoV-2 pandemic,” wrote the researchers, including Professor Javier García de Abajo.

The researchers found that radical social distancing with the associated closure of schools, restaurants, sports clubs, workplaces and travel effectively reduced the spread of viruses, but that the economic and social costs would not be sustainable in the medium term.

They argue that additional measures are needed to reduce virus transmission when people return to schools and jobs that require proximity or some degree of physical contact.

According to the researchers, among the available alternatives, UV-C light meets the requirements of fast, widespread and economically viable use.

“Implementation is only limited by the current production capacities, the increase of which requires rapid intervention by industry and the authorities,” they said.
