A technique that zaps airborne viruses with a narrow-wavelength band of UV light shows promise for curtailing the person-to-person spread of COVID-19 in indoor public places.
The technology, developed by Columbia University’s Center for Radiological Research, uses lamps that emit continuous, low doses of a particular wavelength of ultraviolent light, known as far-UVC, which can kill viruses and bacteria without harming human skin, eyes and other tissues, as is the problem with conventional UV light.
“Far-UVC light has the potential to be a ‘game changer,’” said David Brenner, professor of radiation biophysics and director of the center. “It can be safely used in occupied public spaces, and it kills pathogens in the air before we can breathe them in.”
The research team’s experiments have shown far-UVC effective in eradicating two types of airborne seasonal coronaviruses (the ones that cause coughs and colds). The researchers are now testing the light against the SARS-CoV-2 virus at Columbia in a biosafety laboratory, with encouraging results, Brenner said.

the concept of UBI is not new
Far UV light is not new - God made it many years ago
LOL. So true. Makes little effort to emulate indoors. I currently quarz everything brought from the outside. To have it full time is excessive. It is is 100% harmless for a person it wouldn’t be that harmful for a virus too.
love this idea. reminds me of how Captain Kirk, Spock and McCoy saved Spock and a whole planetary colony from an alien super infection with a dosing of high intensity sunlight. yeah, i know, i was a Star Trek geek as a kid.
Yeah. Inject it into the body. Trump was on to something.
If the eyes are not affected, the rays must be relatively safe for human cells in general,
Perhaps the patient's blood could be run thru a dialysis-type machine and be irradiated as it passed thru a field of the correctly modulated UV rays, breaking down the virus on contact.
Determining strength and type of ray as well as length of time on the machine would be in the hands of the research team.
President Trump may have discovered a new direction for the scientists.
I don’t know if this will work, but I can pretty much guarantee you that if WalMart or Target put up these lamps in their stores, there’d be some cohort of folks claiming that they got skin cancer or vision problems or some other malady as result of UV lights shining on them.
No doubt the Donald knew about this or he wouldn't have opened his yap. He's not the idiot the derps think he is.
He's an actual hands on President that talks to people himself.
The left-scum media got walked into another one.
Dumbasses.
From Science Daily in 2017 UV light can aid hospitals' fight to wipe out drug-resistant superbugs
Excerpt:
"A new tool -- a type of ultraviolet light called UVC -- could aid hospitals in the ongoing battle to keep drug-resistant bacteria from lingering in patient rooms and causing new infections.
Some hospitals have already begun using UVC machines in addition to standard chemical disinfection to kill potentially dangerous bacteria such as methicillin-resistant Staphylococcus aureus (MRSA), but research on their effectiveness has been preliminary.
A large randomized trial led by Duke Health and published in The Lancet finds use of UVC machines can cut transmission of four major superbugs by a cumulative 30 percent. The finding is specific to patients who stay overnight in a room where someone with a known positive culture or infection of a drug-resistant organism had previously been treated.
"Some of these germs can live on the environment so long that even after a patient with the organism has left the room and it has been cleaned, the next patient in the room could potentially be exposed," said Deverick J. Anderson, M.D., an infectious disease specialist at Duke Health and lead investigator of the trial, which included more than 21,000 patients.
"Infections from one of these bugs are tough and expensive to treat and can be truly debilitating for a patient. For hospitals, these infections also cause a burden of costs that often aren't reimbursable."
The researchers focused on four drug-resistant organisms: MRSA, vancomycin-resistant enterococci (VRE), C. difficile and Acinetobacter.
The trial was conducted from 2012 to 2014 at nine hospitals in the Southeast, including three Duke University Health System hospitals, a Veterans Affairs hospital, and small community health care settings.
The facilities used a portable machine called the Tru-D SmartUVC to disinfect rooms where patients with the target bacteria had been staying. For about 30 minutes, the machine emits UVC light into an empty room, the light bouncing and reflecting into hard-to-reach areas such as open drawers or between cabinets and fixtures. The light waves kill bacteria by disrupting their DNA.
The trial compared standard disinfection with quaternary ammonium to three other cleaning methods: using quaternary ammonium followed by UV light; using chlorine bleach instead of quaternary ammonium and no UV light; and cleaning with bleach and UV light.
Overall, the most effective strategy was using quaternary ammonium followed by UV light. This combination was particularly effective against transmission of MRSA.
The researchers found that using chlorine bleach instead of quaternary ammonium cut transmissions of VRE by more than half. Adding UV light to the bleach regimen was even more successful, cutting VRE transmission by 64 percent.
None of the cleaning methods significantly reduced the incidence of C. difficile, an infection that takes hold in the gut. The incidence of Acinetobacter was limited to one case, so researchers did not include it in their analyses."
Put artificial ultraviolet light on nonliving surfaces overnight—not on people.
Let them experiment by putting the UV lights on administrators in offices for a few years first.
ECMO. I don’t think it would work, the blood isn’t in the machine long enough, it has to be kept moving. As he was saying it I thought of that but the answer is “probably no”.
LOL. SOMONE on 4chan has found an actual machine to treat blood with UV light. LOL. Looks like it was from back in the 90s and already has FDA approval. LOL.
The machine looks like it’s from the 40s and wouldn’t you know? It IS. From the pre antibiotic days, AND IT WORKS. Antibiotics are just cheaper.
This is hilarious. It’s almost like Trump knew it was out there and just baited the libtard media.
Didnt the original “Invisible Man” movie have him transfusing his blood with his invention? Haven’t seen that since I was a kid. In black and white. What could go wrong? :D
Our local hospitals have been disinfecting rooms and hallways with “robots” using UV light for at least 10 years.
I am old enough to remember when toilet seats used to fold up into a chamber bathed in UV. Oh look Boeing is talking about doing that on airplanes like it is a new idea.
