On the Shoulders of Giants: Yes Dr Feigl-Ding on Twitter and then there is Dr David Nabarro’s take on Delta variant (Indian).

Eric Feigl-Ding @DrEricDing Why did we not realize kids transmitted #SARSCoV2 last year? Because with the original strain, #COVID19 was milder & more asymptomatic—hence we **didn’t test or measure** kids much. But #B117 (Alpha) and #B16172 (#DeltaVariant) are different—more severe.  HT @sketchplanator
