WASHINGTON â President Trumpâs mention Thursday of treating C****-** with ultraviolet light was part of a rambling digression that included speculation about administering disinfectants to patients, prompting confusion and alarm from medical experts.
The presidentâs invocation of p***********e â which he claimed on Friday had been a joke intended âsarcasticallyâ to provoke reporters â overshadowed the news from the briefing about evidence, first reported last week by Yahoo News, that ultraviolet light does destroy the c****av***s. Researchers have shown it can be used to disinfect surfaces and k**l v***ses in ambient air in ways that could be used to reduce t***smission in public spaces.
âContinuous very low dose-rate far-UVC light in indoor public locations is a promising, safe and inexpensive tool to reduce the spread of airborne-mediated microbial diseases,â wrote a team of researchers in a 2018 paper published in Scientific Reports.
T***smission of the c****av***s is thought to be more common through particles spread through the air than by contact with hard surfaces, but scientists are still working to understand how the v***s spreads.
Yet if commercially available UV products were to mitigate some of the risk of contracting the c****av***s, that might help ease the t***sition out of a total lockdown. âThis approach may help limit seasonal influenza epidemics, t***smission of tuberculosis, as well as major p******cs,â the scientific researchers wrote in 2018.
The key is advances in UV lighting technology, specifically the advent of âfar-UVCâ lamps, which operate at a wavelength of 222 nanometers, a frequency that doesnât penetrate skin or the outer layer of the human eye. Previously, disinfecting ultraviolet could not be used in public spaces because the wavelengths used, of 254 nanometers and up, can cause skin cancer and damage the eyes.
By contrast, the 2018 paper found that âfar-UVC light cannot penetrate even the outer (non living) layers of human skin or eyeâ but that âbecause bacteria and v***ses are of micrometer or smaller dimensions, far-UVC can penetrate and inactivate them.â
David Brenner, director of Columbia Universityâs Center for Radiological Research, said earlier this week that far-UVC light âcan be safely used in occupied public spaces, and it k**ls pathogens in the air before we can breathe them in.â
âMost approaches focus on fighting the v***s once it has gotten into the body. Far-UVC is one of the very few approaches that has the potential to prevent the spread of v***ses before they enter the body,â Brenner said.
A group of researchers at the Center for Radiological Research published a study in 2017 that âtested the hypothesis that there exists a narrow wavelength window in the far-UVC region, from around 200-222 nm, which is significantly harmful to bacteria, but without damaging cells in tissues.â
The study found that far-UVC light k**ls pathogens âwithout the skin damaging effects associated with conventional germicidal UV exposure.â
Two other studies have examined the impact of far-UV light on skin using mice and found that â222 nm-UVC lamps can be safely used for sterilizing human skin.â
One company, Healthe, is already selling a few different UV light products, including far-UV lights meant to be used in public spaces. One is a downlight that can be installed in the ceiling of an average room. There is also a portal, similar to a metal detector, that claims it âinactivates over 90% of contaminantsâ if a person stands â arms up â inside the portal for 10 to 12 seconds.
The company says another way to use ultraviolet is to irradiate air as it passes through a sealed unit, like a building air-conditioning system. Since that doesnât expose people to the rays, it can use different, more powerful wavelengths.

You totally missed the mark.
Try this line of digging (and look at the companyâs share price history.) Their technology uses tiny uv lights on a probe that has already been used in patients with Chrones disease and other gut diseases. This technology shows promise for use through a ventilator to k**l v***ses in the bronchial tubes.

Iâve also just been reading about a technique for saline lavage of the thoracic cavity - whoâs to say adding medication of some type to the saline would not do an even better job.
Finally, there is a barrage of stuff on the web after President Trumpâs supposed gaffe Fromm the alternative medicine practitioners in support of looking at alternative therapies. Some of those therapies have been around for the ages - their only disadvantage being they donât make profits for big pharma.
You watch - whether his words were inadequate or not - the concepts he was trying to get us to look at will likely prove him prophetic.
