I continue to check my little dashboard of San Francisco COVID numbers each morning to estimate risk of inessential-but-nice activities, e.g., whether I want to celebrate National Fritter Day with a fritter purchased inside or outside. Alas, San Francisco's numbers have gone up lately, so I shall settle for an outdoor pushcart fritter this year.

chart showing three San Francisco COVID measurements over the last couple of months. The line of New Cases is low, but rising. The Wastewater line has been above the pretty-safe level for a while now. The Test Positivity% line has crossed the pretty-safe level, recently going from pretty-safe to not-so-safe

Looking at the graph, you might wonder what was going on in San Francisco's sewers in mid-November: the COVID-in-wastewater ~doubled, stayed high for a while, then dropped back down. This mostly overlaps with that big APEC conference, but not totally. The COVID-in-wastewater surge started kinda early and and ended kinda early compared with APEC. (Maybe each APEC VIP has an "advance" team that they send ahead of them to set things up at each place they travel? And maybe folks on such advance teams, between them, carry about as much COVID as San Francisco's population? Seems like a weird theory, but I don't have a better one.)

Anyhow, I'm taking a break from going inside public places. I mean, I like apple fritters, but it would be too embarrassing to tell the doctor I noticeably boosted my Alzheimer's risk for one.
