If Covid were really over, or “no big deal”, masks wouldn’t anger people.
No one cared when you wore a mask before the pandemic.
People are irrationally angry at those of us still masking, because it reminds them of their failure to adapt. Of the risk they’re taking.
They can’t cope with it.

The autumn Covid wave is likely peaking.
Sept 12th update:
Wastewater daily inf estimate increased to 600k this week. Positivity and ED data have both peaked and begun to retreat, and I expect wastewater will soon follow.
🔸600,000 new infections/day
🔸1 in 55 currently infected
🔸1 in 140 infectious out of household

I eagerly await the results of a multi-center trial (which I hope someone is planning).
