Estimates for the most recent common ancestor point to mid January for France [0]. Of course these numbers could be wrong. But I suspect the level of surveillance of genomes allows for bioinformaticians to keep a close eye on what the virus is doing in a big picture evolution sense. They do note that while most samples are of `A2` strain virus (only meaningful at genotype level, not at phenotype) there were some samples from different genotype branches. Maybe their analysis finds the date for a later introduction of the virus which is different from the potential cryptic transmission occuring in late Dec? 0. http://virological.org/t/early-phylodynamics-analysis-of-the-covid-19-epidemics-in-france-using-194-genomes-april-10-2020/467 http://virological.org/t/early-phylodynamics-analysis-of-the...
