Went to a donut shop in Japan today.
They had a CO2 monitor on the counter and a UV light on, plus circulating air through the ventilation system.
Also all the staff and most of the customers were masked. 😷
It's really not that hard and if a donut shop can do it we can certainly do it at least in schools and hospitals.
This is more what I'd think "Live with the virus" looks like. What we're doing feels more like "Pretend there is no virus".
Edit: UV light is a bug zapper.
@pezmico What kind of "UV light" might that be?
I have a hard time to find reliable info about UV/ UVC / Far-UVC. That is maybe helpful technology, but it is potentially dangerous, too.
Which solution/ product has usability for the "normal" user?

@better_tomorrow @pezmico Naomi Wu has a great video where she builds a ceiling lamp and tests its effectiveness. #UVC is very dangerous, so do not just put up UVC lamps in any occupied spaces. Naomi talks about that in length.

As for consumer products: Philips Lighting has several options, and these should be safe if used properly: https://www.lighting.philips.com/main/products/uv-disinfection
Also: UVC is used to keep fishtanks clean - it kills algae and other bacteria. But it can also kill all fish.
@fihu @pezmico Thanks, i will look into it.
I already have a Philips Aircleaner working with UV, but in the end it is not what i am looking for, because it is a closed system. The other Philips consumer products are not suitable with lifeforms around, as i understand.
I am searching for a solution where you can still be in the room (safely).
@better_tomorrow @pezmico I guess the ceiling lamp Naomi built is okay - and Philips has professional versions of that too. Basically, it generates an UVC "field" beneath the ceiling which then does its job on viruses and other organics stupid enough to rise up to the ceiling.
Just make sure there are no reflecting objects inside the field… 🪩
There are many ways to use UV light against diseases. It can be very confusing. Some are great, some are useless and some are bad. I break down all the ways it can be used here. https://itsairborne.com/intro-to-uv-light-against-diseases-b4f0ab839a09
Here is a article looking into the complexities of the subject.
The author Jose-Luis Jimenez is on Mastodon.

There are UV sterilizing lights available for ducted air conditioning systems.
~AUD$1000 fitted was the quote.
AIUI they do a good job of sterilizing viruses and bacteria.
But I have seen a caution from someone who seemed knowledgeable - UV light can increase amounts of cancer causing chemicals in the air and so using a UV light in a confined poorly ventilated space could result in in lung disease.
It seems complex.
Peer pressure is disheartening. Don't let yourself get infected, or infected again. Dont pass on an infection you didnt notice or worry about.
@pezmico The non-democratic aspect of that phenomenon is basically there has not been a law which demands you to do such things.
It's not like "we make the rule, we live together by following it." Instead, it's like "I follow the herd, so that I won't be blamed by anyone."
Wearing a mask, taking a vaccine, and everything is essentially based on the same mentality; not for the sake of us living together, but to dodge unknown third party's negative judgement.
Just my two cents.
