We changed the vocabulary until the crisis sounded historical.
Changed the surveillance until the

You’ve got to hand it to them.
They changed the language.
Changed the guidance.
Changed the metrics.
Changed the dashboards.
Changed what counted.
Changed what we counted.
Spent months arguing droplets while the virus rode the fucking air.

I built an Adult Literacy Program for a guy on the spectrum who reads at a 1st-grade level. If you know someone who can use it, be my guest.

@ijsimo25 Sorry, I should have been more precise:

“Covid is over.”
“Covid is a nothing-burger.”

@drseanmullen The parallels of this pandemic to the timeline of events relating to HIV/AIDS public health response are staggering and disheartening. If the timeline is comparable, we won’t see adequate movement for at least a decade. I truly hope that’s not the case.
