      It’s coming—#DeltaVariant is now >96% dominant in 3 major counties (UK, Russia, Portugal). It is surging exponentially in the US at now 31% of all cases, up from ~10% just a week ago.

      Troubling—the worst variant to date, the #DeltaVariant is now the new fastest growing variant in US.

      10) Okay, let’s get serious — how fast does #DeltaVariant spread? It is 2x faster than old Wuhan strain, so many estimate the R0 is 6-8 now for Delta. And it spread so fast, that even “fleeting” exposure just merely seconds can infect a stranger in a shopping mall. See thread 🧵https://twitter.com/DrEricDing/status/1406779894785351688 …

          15) this is why many of us are so upset that it took the CDC a full month delay to declare #DeltaVariant a higher risk VARIANT OF CONCERN just last week — a full month after WHO declared it a VOC and 3 weeks after UK 🇬🇧 declared it a VOC.

          21) #DeltaVariant yields much lower vaccine efficacy—especially for 1 dose. But it can be compounded by elderly age and other risk factors. We need everyone 2x vaccinated but also wear masks to protect the elderly and vulnerable even if vaxxed. See video.pic.twitter.com/dJKox4ew22
