| Popis: | We provide an easy and accurate method for approximating the reproduction number R0 defined in an SIR epidemic model. At first, we present a formula extracting the exact R0 in case of constant rates of infection and recovery assumed in an SIR model. Then, we proceed proposing an exponential fitting to various data taken from the real‐world epidemics. Certain applications for current COVID outbreak are considered, and figures describing the fluctuation of R0 in various countries are given.
