Opening schools increase the spread of COVID-19 ~24%

in our local schools, we have a locally adopted mask mandate. biggest value to having it is how it ripples out to close contacts of exposure.

if the close contacts and the covid-positive person were masked full time, then no quarantining is needed for the close contacts if they are symptom free. so the district does not have to yo-yo kids in and out as one more kind in each class finds out they have it week after week.

the district looked at the quarantine as recommended by CDC and local board of health and didn’t think they could take on liability of ignoring the quarantine advice. maybe they could, who knows.

Got it. Wasn’t sure which state or what the SC decision was. Thanks for clarifying.

Our school district has had really lax quarantine rules. Unless five kids in the same classroom get it within two weeks of each other, nothing happens. No one quarantined, no remote learning, no yo-yo-ing of the kids. Masks are optional (most don’t). Seems to have worked out relatively fine this semester, compared to the stricter districts in the state. My kids elementary school hasn’t had to do any quarantining / remote learning for any of the grades.

In the state where my colleague is involved the big battle of arguments is one between the change in risk (benefit) of masks against the cost (government overreach + impact on children). You can have something that is hugely successful that is still struck down because it fails in this comparison in the judge’s view.

A little editorializing but especially if we’re going to make arguments that children should bear even small costs for benefits that they won’t directly see, or benefits that aren’t in a significant way proportionate.

well that’s good that it has worked out well. still not sure if someone would try to assign liability for not following the cdc quarantine recommendations, but glad it has not yet happened. (claiming with certainty where an exposure came from sounds difficult, I am sure.)

I got this via al Jazeera, and can’t figure out how to post a link. But this seemed relevant and actionable:

Corona infections and air quality

More infections in poorly ventilated classrooms

Dec 9, 2021 | KANTON GRAUBÜNDEN / EMPA

Indoor air quality has an influence on how many corona virus infections occur there. This has now been shown for the first time in a pilot project involving Empa researchers in 150 primary school classrooms in GraubĂźnden. The analysis also showed that the air quality in many classrooms is poor. The study concluded that regular ventilation of classrooms is therefore very important, even in winter months.

Do we mandate ventilation requirements for schools, particularly in light of COVID?

I don’t know if we even mandate ventilation for restaurants. I saw some great ideas early on, like putting UV lights (which kill covid, flu, and many other viruses) above a false ceiling and circulating the air through the illuminated space. I’ve heard nothing about implementation.

:man_shrugging:

Maybe it’s happening and i just haven’t heard.

Not just schools, but because of Covid there should be code added around ventilation for all construction. First amend the code for new constructions and then say by 20XX all existing buildings must be up to code.

We built a house a few years ago and have an air exchanger that we can set to run X number of minutes an hour that basically circulates in outside air into our house.

Lots of older buildings have no ducts, and no easy way to add them.

our district had just finished a construction project that improved all the HVAC. came in handy once people started asking about putting HEPA filters (or is it HIPPA filters) in all the classes. The consultants were able to talk about the quality of the filtration AND the recirculation rate.

older buildings could not be completed fast enough to matter (1-2 years, esp if demand went up). so then it would be a gazillion portables in class rooms that are 900-1200 sqft w high ceilings. so lots of units.

HIPPO.

I think it will always matter. It might matter LESS in 10 years, but it will still matter and still be a good idea and make us more resilient in the face of the NEXT epidemic/pandemic.

of course it will matter down the road. but for the current event that is driving the push, it won’t happen broadly enough to impact things unless we have 2+ more years.

It’s still a good idea. The current pandemic is highlighting why, but it will still be a good idea in two years.

School district dropped mask mandate a week ago. We got a notification Friday of a direct exposure in one of our kids’ classrooms. That didn’t take long!

Fortunately our son who was exposed wears a mask, and hasn’t presented with any symptoms yet, so seems he avoided it. He is also the one who had covid in November.

Well, we are supposed to be at a point where one infection won’t spread to widely or too quickly, due to vaccinations and prior exposure.

This is a rare opportunity to see if that’s true, or if the thread title is true.

My wife works in a school. She still wears a mask regardless of the status of the mandate, having a brother with asthma who works in “The Industry.”
My local ZIP code Positive Case Rates are below (i.e. good) the “goal.”

I notice the article doesn’t say anything about the mortality rate among those kids’ grandparents.

Probably because it’s unremarkable.
