Short thread. I keep seeing claims on how some places may have reached herd immunity & calculations on whether a variant is more virulent or disporportionately affects the young etc. These are not easy things to discern so let’s not do confident back-of-the-envelope calculations.

True seroprevalence is not easy to figure out outside of true random sampling—rarely done. A lull in cases after a surge? Maybe, maybe not. (Not very likely, to be honest). Blood bank etc. sampling? Maybe. Confounding issues are thorny. Modeling? Very parameter dependent. Hard Q.

Seroprevalence is also not the sole metric to assess herd immunity
