Installing air filters in classrooms has surprisingly large educational benefits (2020)

Anecdote: Our daycare was a plague ship right after covid 'ended'. None of the kids had any immunities, and they made up for it in a hurry. Man, what a terrible year.

As a result, the daycare got a grant to get N-95 air filters installed and those UV lights that Chinese restaurants tend to have in the bathrooms. One per room.

What. A. Difference.

The infants and kids coming up are not nearly as sick, and when they do get sick, it's not nearly as terrible. The RSV vaccine has also been a godsend.

I can't really tell/feel what what the silver bullet here, but the combinations have been amazing. So much so that we got them for the house.

Nice story. I can believe it. I was surprised that you mentioned the RSV vaccine. Last I checked, they were still working on it. I was wrong: There are three competitors now: (1) Arexvy (GSK), (2) Abrysvo (Pfizer), and (3) Mresvia (Moderna)

Normally, I use this clinic in Thailand to compare prices for vaccines: https://www.thaitravelclinic.com/cost.html

The RSV vaccine is crazy expensive, even more than the HPV one. Over 200 USD is incredibly expensive in a developing country (like Thailand).

I never heard of this. Does anyone have a link to one of these on Amazon or Alibaba? I am curious to learn more.

I wonder how much of the improvement was due to reversion to the mean. When bringing everyone back, you would expect a sharp peak of infections which would decay to normal levels after a while - filters or not. I'm sure they do still have some positive effect though.

Anecdotally: it was a big effect.

Rigorously: no way to tell now, the time has passed.

Likely: you're right. But what little staff is there from pre-covid says that they have helped a lot too.

Reality: here's $500/wk and my kid, in return I get really sick for a year no matter what.

What lights are you talking about? UV capable of disinfecting isn't something you want to be looking at. (Are you perhaps thinking of the bug-zapper lamps that are sometimes described as UV? Way up at the top of the visual spectrum, a lot of bugs go for them. But they're just a lure to get the bug between the high voltage wires that actually kill it.)

The only disinfecting UV lights I've heard of for use in occupied areas are hanging things that only point up where nobody's going to be exposed. I have heard of some research for safe UV lights that are high up in the UV, they actually still burn but without enough penetration to get through the dead skin layer.
