The model estimated patients' mortality (4.92%) and recovery rates (95.08%), virus incubation (8.54 days), infection periods (18.65 days), as well as the basic virus reproduction number before (R0 = 11.60) and after (R0 = 0.39) lockdown. The predicted values were accurate until the 70th day. The performances achieved by the model were 0.98 for infected, 0.97 for the recovered and 0.97 for the dead, asserting the model's great performance (>0.75). The model also suggests that on February 15th, 2020, there were 67 infected individuals in the incubation period. We believe that this model can help other studies to better understand and accurately predict epidemic curves, mainly in countries where the new coronavirus has recently started to spread. It also may guide public health policies that aim to control the disease. © 2021 NSP Natural Sciences Publishing Cor.
