    1. David Fisman. (2021, July 8). Fascinating new preprint on delta vs older variants in well-investigated outbreaks in China. Viral load for delta is 3 log higher, and latent period is shorter too (estimate is 4 days vs 6 days). This may explain much higher R estimates which may be due to elevated viral load [Tweet]. @DFisman. https://twitter.com/DFisman/status/1413126886570536963
