Blue dots are the genetic distance among SARS-CoV-2 inferred from data collected in China between 12/23/2019 and 03/24/2020. The error bars are standard deviation of pairwise distance propagated through the equations. The brown line shows the genetic distance estimated with Eq (2) and the Chinese epidemic data. The interval around the brown curve is a ±10% error interval on the value Bμ, which we considered to be Bμ = 29900 × 0.001/365.
