(A) Time course of the Mexican epidemic with (B) the posterior estimates (median and 95% CrI) of the reproduction number over time obtained under Poisson and negative binomial models from the analysis of confirmed cases. The estimate ofthe negativebinomial dispersion parameter k is for a low-to-moderate overdispersion, but this is enough to greatly increase the uncertainty in R(t).
