MONDAY, Feb. 12, 2018 (HealthDay News) -- As a particularly nasty flu season rages across the United States, scientists have found a powerful new disinfectant that makes "light" work of the virus.
Researchers say a certain spectrum of ultraviolet light -- called far-UVC -- easily kills airborne flu viruses while posing no risk to people.
It could offer a new, inexpensive way to eliminate airborne flu viruses in indoor public spaces such as hospitals, doctors' offices, schools, airports and aircraft, said the team from Columbia University Medical Center in New York City.
The disinfecting success of initial experiments still need to be confirmed, said lead research David Brenner.

Yes, and you really don't need much ozone to make a huge difference to knock down germs and viruses either. Around normal summertime level of .03 - 05 ppm works plus it has the advantage over UV of because it can penetrate every nook and cranny and anything porous that normal air can get to without causing any deleterious effects to the human body. It won't work fast at those low levels, but time itself is a mitigating factor of how will ozone can do it's job overall.
Some smart thinking hospitals use it too, especially in the operating rooms between surgery's at much higher levels.
I got a toothbrush holder from Rite Aid years ago.
It’s already widely used in ventilation systems
In your body however you cannot use ultraviolet light
The silver I am on kills all viruses inside your body
it is known as colloidal silver; you can buy or make it for free
Far UV-C provides for a safer narrow-band light source in the UV spectrum which poses little to no harm in operation to any exposed humans. The instant-on deuterium excimer lamp which generates this light is not the long available UV generating mercury vapor lamp.
This is also how the high frequency consciousness of prayer heals.
I remember when toilet seats used to fold up into a chamber bathed in UV light. Probably not F-UV or strong enough. That was 50 years ago.
The new light source acts quickly on virii floating in the air, seconds rather than minutes to achieve a kill.

However, "because viruses and bacteria are much smaller than human cells, far-UVC light can reach their DNA and kill them," he said in a university news release.
Why did they quit using it in hospitals?
It is inexpensive to install in hvac systems and effective. Same for water treatment. Been around for that application for a long time.
My take on hospitals is they are a good place to get sicker.
UVC-emitting LED’s are available and require MUCH less supporting electronics than either mercury or deuterium lamps and are far more efficient.
also because infectious diseases became less common thanks to vaccines and because antibiotics lowered the risk of spreading infection. (treated TB stops being infectious within a week, for example.
part of it was that the “experts” started pooh poohing all those old fashioned treatments used for years by ordinary docs: they didn't approve unless they passed a test.
Some UV tests showed they helped, but others showed they didn't help since you caught the disease anyway outside of the area where the light was shining.
Thanks for the reminder. We just got home and I have to flip our crap over so the UVc light gets all sides. Keys, phones, glasses, etc. I built a box with aluminum foil and have the stuff on racks, but I like to flip them like pancakes just to be sure.
I’m pretty sure that this FAR-UVC is different than the UVC lights on the market today. The existing ones ARE hazardous so you have to leave the room or confine it in a box.
These new ones (not on the market yet??) are safe for humans (and animals).
A friend of mine and I, both retired engineers, have begun a for fun study of using UV to tread air in HVAC systems. The systems are commercially available. Honeywell make some of them. The question is how effective are they? How much intensity and residence time is required to be effective?
Some people, new kids on the block usually, have to make a splash to change things when they don’t know why they are there in the first place. There are other ways to apply UV than by direct exposure. It depends on what you are trying to prevent.
Some of the infectious diseases we dealt with and subdued have revived. Nothing stays the same. Maybe some old ideas need to come back. The amount of infection in hospitals now just feels unrealistic and unnecessary.
In UV light, it was partly the toxicity of the old fashioned mercury bulbs, and partly because one study using the lights in schools didn't stop a measles epidemic since the kids caught it outside of school.
Medicine was becoming crazy when I retired ten years ago, because we were supposed to obey “proven” therapies, yet a lot of us knew the studies they lumped together to figure out what worked were flawed.
Alas, given the FDA’s rigid regulations no one is pushing this to clean surfaces or even money, although China is using it to clean up the insides of buses.
For most of the years I worked all I had to do was the right thing. Just do what was rational, reasonable and respectful and build on my formal education. I never bothered with regulations or rules because I was invariably exceeding them in my own self-established protocols.
That all changed when SHE became the rage and we were forced to do what someone else thought right and usually not rational.
I never conformed.
I have seen many great ideas thrown out for the wrong reasons and dismissed forever and forsaking new technology that is the solution to the reason the ideas or processes were thrown out.
My doctor just retired and I’ve got to find another. He assured me he would work another 4 years or so two years ago. I was one of his very first patients when he was maybe 8 years older than I. I probably am a contributing cause to my own problem. I went for my checkup at his first appointment of the day as per usual. He was grousing about having to sign “prescriptions” for something like 2,800 lab orders that he had never had to do ever before, new protocol. He was also wrestling with yet another new medical records computer system and would rather talk to me about my cows and fence building. I said, “Doc, there is one bucket for money and one bucket for crap. When one bucket gets full, you go home.” He retired three months later.
It can kill more than Viruses: Does UV light kill insects? What about other types of light?
The problem is getting exposure to such, but not you.
Put UV light at intervals inside the air ducts, to kill germs and viruses, rather than have them get re-circulated all through the building.
