In this paper, we have calculated the basic reproduction number ( R _{0}) and doubling time ( T_{d} ) for the novel Coronavirus disease 2019 (COVID-19). The calculation is performed for March 2020 from the data provided by worldometer. We have investigated the data for Germany and Bangladesh. The calculation of R _{0} is performed based on SIR model. The parameter T_{d} is estimated based on the new cases of each day. Since T_{d} and R _{0} in use to judge the lockdowns and other measures to prevent spreading of the virus, we have provided simple approximation of both parameters.
