Based on the released data, we attempted to estimate the mean values of the main epidemiological parameters, i.e. the basic reproduction number R 0 , the case fatality (ĝ) and case recovery (b) ratios, along with their 90% confidence intervals. Then, as described above, we provide coarse estimations of the "effective" per day recovery and mortality rates of the SIRD model based on the reported data by solving the corresponding least squares problems.	./cache/cord-266797-uglsx7se.txt	./txt/cord-266797-uglsx7se.txt
