Delta (light orange, second from left) is the curious exception: stayed flat or slightly rising, then shot up. That sharp rise in Nov 2021 sure looks like seasonality! I also wonder whether Delta wasn’t also a series of success variants, unobserved because genetic testing wasn’t tracking such fine-grained variants yet.
Regardless, I’m cautiously hopeful for a summer here of safer conditions than we’ve had in a while.
