Wastewater evidence from the eastern USA is also pointing to fast-up/fast-down.

Pathology There has been a lot of discussion of Omicron being more mild, and there being a “decoupling” of case rate and hospitalization/death rate, but it was hard to tell because hospitalizations and deaths lagged. It also varies by the demographics of the local population and how much prior (partial) immunity the population has. One… Continue reading 2022-01-08/09/10 General
