3) here are the specific details of each govt intervention’s R reduction and their 95% CIs from@the study.
4) As Professor Greenhalgh points out, if schools open; they should definitely reconsider the meager 2 meter rule. It doesn’t work for an airborne aerosol virus. Not only masks, but ventilation— and HEPA Filters key if no ventilation. https://twitter.com/trishgreenhalgh/status/1347545904241381379
5) Here is the latest data on attack rates of the new B117

6) However, Denmark CDC is worried that merely crushing the R slightly below 1 is not enough since they anticipate the new B117 variant will require us fast action to crush the R<0.7 in order to contain it by Feb/March. https://twitter.com/drericding/status/1346899021621813249
