$OCGN Delta variant has yet to be labeled as a variant of concern by CDC, yet the proportions of the variant are changing rapidly. It has moved from 14th most prevalent variant in the US, to 8th, to 5th, and now 3rd. The percentage of the variant is more than doubling every 2 weeks with comparatively little selective pressure. For those who are interested, I have graphed the proportional changes of Gamma (P1) and Delta (B.1.117) variants vs time. At the current rate, Delta will become 2nd most prevalent variant in the US in less than 3 weeks.
