There's Light at The End of The Tunnel
It's Far-UVC.

Far-UVC offers an additional level of protection in most cases.

Far-UVC at 222 nm barely penetrates your dead skin cells, and most of it gets absorbed in the tear layer of your eyes, but it still kills germs. UVC researcher Ewan Eadie said, "Far-UV exposure of 30,000 hours or 3.5 years is equivalent to 10 minutes in the sun."

I just found a smart #Twitter thread on the ins and outs of 222 nanometer far-ultraviolet light, which I think could help end #Covid forever:

@joeyfox85 is an engineer who tweets about anti-Covid engineering. I made a #bot to follow him on #Mastodon: @joeyfox85 (works on my instance, YMMV) 

TL;DR: #222nm UVC light kills Covid (and #MRSA, #RSV, #flu, etc.) but doesn't burn skin or eyes like the 254nm UVC used now for disinfection (and tanning beds).

A 20w 222nm bulb can disinfect a room in 5-10 minutes with no risk to people or animals. 222nm LEDs could be even added to regular LED bulbs to disinfect every room in your house.

But the tech has only existed since 2020, so it's expensive: $1000/bulb, as opposed to $50/bulb for 254nm. And it hasn't been tested enough to know if it's safe for the skin biome or people with #AutoImmune disorders.

The problem is that almost nobody makes 222nm lights. If we made them at the scale we make 254nm, prices would plummet.

Very promising for #covid, but also hard to get right and use safely. Even the comments following the thread show how poorly people understand the subtleties (eg, thinking UVC has anything to do with CO2). Not only is more study needed, devices will need careful testing to ensure they only emit in the narrow band, and there's huge opportunity for dangerous, misleading and/or ineffective products. 1/3
