Reminder, folks: the COVID19 pandemic is NOT over, it's just that the big commercial landlords decided it was hurting their business rents so leaned hard on the politicians and media to SAY that it's over.

Right now China is in the FO phase of FAFO, and involuntarily providing an amplifier for a new extra-virulent strain that'll make an end run around our half-assed vaccines AGAIN.

Stay safe in 2023!

I will add that masking/distancing/vaccination is all good, but what we REALLY need is forced PM2.5 air filtration in all public spaces. Schools, hospitals, universities, shops, restaurants, cinemas: on trains, buses, planes, and passenger ships. And ESPECIALLY schools and hospitals. These premises have always been viral disease amplifiers, but filtration stops it spreading at source.

@cstross What happened with the ultraviolet light that was supposed to kill airborne Covid whilst being harmless to humans? That could be handy right now. (Or even the non-harmless varieties, bathing the interiors of air recirculation ducts.)

@acb @cstross
Anything that would fry virus would fry human skin.
And UV ing spaces when humans aren't there isn't worth it because the virus inactivates pretty quickly after it's floating around in the open air.
It's like Trump's internal UV disinfectant idea, only on your skin

Far UVC is a different wavelength than traditional germicidal UV. 222nm is safe for humans, but lethal to coronaviruses.
