Endemic is not an improvement on the situation. It’s just an acknowledgement that we were inadequate to deal with it when it was reasonably possible, and are giving up now. I don’t leave the house without a P100, because my species appears to be insane.

I wear a P100 because I can’t trust my fellow Americans to wear so much as a scarf.

What do you mean, “since”? COVID is still running freaking riot. We just stopped acknowledging it.
