masks, ventilation, and filtration work in schools; social distancing and plexiglass don’t do anything

There, I think my headline summarized by layman’s understanding of this study published by CDC. I’m hoping my (rising) third grader won’t have to wear a mask to school in the fall, but that wouldn’t be the end of the world. What I’m really hoping for is five full-time in-person school days, which kids really need for normal educational and social development at this point. Masks would be a small price to pay for that until younger children can be vaccinated, but really can we speed that up.

I’ll give the School District of Philadelphia some praise for comprehensive testing of its HVAC systems district wide, followed by correction of problems. What they found though was that many classrooms had no functioning ventilation at all! I suspect they were like that for many decades. How many flu epidemics ravaged the city in that time because this city has a culture of accepting amateurism, mediocrity, and incompetence? I want to see the pandemic money spent to bring school buildings up to date, starting with HVAC and air conditioning. Air conditioning isn’t a luxury these days. It’s getting hotter and this would mean the buildings could be used year-round which could have enormous benefits.
