Snippet: A simplified method to compute $R_t$, the Effective Reproduction Number, is presented. The method relates the value of Rt to the estimation of the doubling time performed with a local exponential fit. The condition $R_t = 1$ corresponds to a growth rate equal to zero or equivalently an infinite doubling time. Different assumptions on the probability distribution of the generation time are considered. A simple analytical solution is presented in case the generation time follows a gamma distributi
