Technically, covid is not yet truly endemic, though most people are behaving as through it is. At least we do seem to be past the worst of it, according to hospitalization rates. But since at-home test results are rarely collected, the infection rate data is incomplete at best and should be considered unreliable data.
But would I go to OSH next year? Yes, I hope to. This year and last year simply didn’t work out for reasons completely unrelated to covid. But I’ve never been a part of the “I go every year, full stop” crowd, so missing a few events isn’t a big deal to me.
