Is there a book like White Fragility…
but about American adults and the air they breathe?
Because someone needs to write the book on why a nation that buys air fryers, air fresheners, air purifiers, scented candles, and aromatherapy oils…
won’t fight for clean air that keeps their children alive.

On Monday, I'm talking with an expert about ***indoor air quality***. This is a subject I've been meaning to cover for years. Very interested in the overlap between this & pandemic prevention, climate change, economic justice, etc.

Can any other chronically ill/immuno-meh folks who have had Covid tell me about their timeline?
I'm starting to get concerned. After two weeks of illness and one full round of Paxlovid, I'm still sick, still have a fever, still testing strong positive.

I know a doctor who said even when they personally are sick, they don't test for COVID, because their actions would be no different than if it were a cold.
That's honestly infuriating. Every transmission is an opportunity for the virus to mutate, and also for someone to be sickened/harmed.

If our culture wasn't so misinformed and resistant to masks as an air health protection, I would expect officials would issue air alerts and distribute masks in critical wildfire smoke zones. We see water warnings at contaminated beaches but seem to do little about contaminated air. 🤷♂️

It’s Pediatric Sepsis Week.
Sepsis is the #1 cause of death in kids—about 1 in 3 survivors experience chronic health challenges.
Preventing infection (clean air, hygiene, masking, vaccination) is critical.
Future digital tools may also play an important role in early pediatric sepsis response:

The truth is, we never, in any systematic way, made classrooms safe, like ensuring upgraded ventilation and air purification in schools.
And COVID ripped through classrooms. Kids fueled household spread and hundreds of thousands of them lost caregivers to the virus.

We need to stop making concessions to the right bc right-wingers get mad.
There’s this big effort to rewrite school closures. Even in ostensibly liberal media, we get solemnly acknowledgments that schools were closed too long.
Not bc of data, but bc right wingers screamed about it long enough.
