Can UV light eliminate COVID-19? [Video]

WHAT’S BEING CLAIMED:

  • Experts worldwide are working on the potential of UV light to eliminate coronavirus less the harmful side effects.
  • The CDC explains that UVC can be a disinfectant against viruses since it emits the highest energy among all the UV types.
  • An expert from the Henry Ford Hospital explained the technology was already available for many years, and research is still under review if the same UVC can kill COVID-19.

For decades now, ultraviolet light has been utilized to break pathogens. The question, though, is,  can it combat the coronavirus, the infection which caused a worldwide health crisis?

The answer, however, cannot be answered by a simple yes. That is because the right type of UV is needed with the appropriate dosage and involves an intricate procedure that should only be done by qualified specialists. Thus, any UV-light devices claiming it can kill the bug is highly unlikely accurate.

UV energy has three different qualifications, such as UVB, UVA, and UVC.

The Centers for Disease Control and Prevention (CDC) explains that almost all the UV radiation that extends to Earth is UVA because nearly all UVB and UVC rays are screened in the ozone layer. CDC added that the UVC could be a disinfectant because it has the highest energy.

Detroit Henry Ford Hospital Photomedicine dermatology expert and physicist Indermeet Kohli explained to Live Science that UVC was already available for many years.

She added that a wavelength of 254 nanometers has earlier successfully deactivated coronaviruses strains, including H1N1 influenza, Middle Eastern Respiratory Syndrome (MERS-CoV), and severe acute respiratory virus (SARS-CoV).

Scholarly research posted to the medRxiin database on June 26 from Kohli’s contemporaries awaiting peer review has confirmed that UVC can also eradicate SARS-CoV-2.

UVC-254 reportedly works since its wavelength damages the DNA and RNA with adequate exposure, making it unable to spread or reproduce that leads to the disabling of the virus.

The specialist noted that accurate data support the technology, and its safety and ease of use make it ideal against the outbreak. She warned, though, that administering such be done with extra caution and experts only as the light can damage the DNA, especially the eyes and skin.

Dr. Jacob Scott had similar observations with home UVC lamps, adding that it cannot kill the virus.    A research physician in the Department of Translational Hematology and Oncology Research at Cleveland Clinic, Scott told Live Science that while UVC can only kill the bug with the right dosage and the right conditions.

Both Scott and Kohli, with their respective teams, are developing a more effective UVC decontamination of personal protective equipment (PPE), including N95 respirators and face masks.

Kohli urges hospitals and sellers to repurpose UVC equipment for N95 decontamination. Meanwhile, Scott’s team created a machine for smaller sized medical facilities and a program that assists users in identifying the disinfection level on a room so staffers can administer the appropriate UVC dose.

While there are current discussions about unharmful UVC such as UVC-222 and Far-UVC, Kohli confirmed that the light has potential but more research will be needed to be sure.
