Read excerpt
Last Friday, I presented a history of SARS-CoV-2 variants, talked about the current and future direction, and then took questions for 40 minutes. You can watch and listen here. The Zoom call went so well we have decided to do this every Monday, starting next week and continuing through the end of the year.

Here is the latest data we have on our GISAID+Wastewater Derived New Daily Infections (NDIs). To my surprise, a member of the XFJ family, RW.1.1.2, has taken over the top spot.
