We obtained an effective reproduction number that was divided by a factor 7, compared to the estimate of the R 0 carried out in France at the early stage of the epidemic, before the country went into lockdown [a value R 0 = 3.2 was obtained in (15) ]. ./cache/cord-272085-4mqc8mqd.txt ./txt/cord-272085-4mqc8mqd.txt
