The coronavirus is spread almost exclusively by airborne and aerosolized particles, as scientists have known for months. Despite scientists’ growing certitude about how the pathogen is transmitted, many establishments have continued to insist on strict sanitization protocols. In some school districts, for example, classrooms close for full-day “deep cleaning.”

The persistence of such practices has led to the advent of a derisive term — “hygiene theater” — to describe rituals that appear to do little to stop the virus from spreading. It is not clear if the CDC’s new guidance will lower the curtain on those theatrics, given how entrenched some of those practices have become.

“If we took half the effort that’s being given to disinfection, and we put it on ventilation, that will be huge,” University of Colorado atmospheric chemist Jose-Luis Jimenez told the scientific publication Nature for an article published last month.

good points...but not related to Alaska politics?

Thank you for posting that. Hygiene theater — very good.

“If we took half the effort that’s being given to disinfection, and we put it on ventilation, that will be huge,”

I was an HVAC/Controls guy. I promise you, almost no schools, grocery stores, office or medical buildings meet the building codes for ventilation (fresh outside air exchange) from their heating/cooling systems. Most office, grocery and other buildings have cheap package units on the roof that can't provide the fresh air exchange. Plus it drives energy costs to heat/cool outside air compared to the recirculated air from the building.

I have been tempted to make the owners of my doctors office building prove to me they are complying with the ventilation codes. I am sure they aren't just because I know how this stuff works.

If that's the case. Why wouldn't it always have been prudent to run industrial "air ionizer" units in stores, bars, restaurants etc?

Back before the Maine control freaks banned smoking in "public places"...the private sector had already solved the problem with these units, and many may still have them either still installed, or stashed in the back room.

I've experienced their effectiveness, sitting across the table from a smoker, couldn't smell it. The smoke went straight up and disappeared. Aerosolized particles should be affected in the same manner.

(if there is actually any bat-flu present)
