摘要：
This paper deals with the outbreak of COVID-19 in Brazil. The new focus of the Corona epidemic via an introduced mathematical model, and a relationship between the stability of COVID-19 free and pandemic equilibrium points and the basic reproduction rate has been studied. According to the presented model, we give pandemic prediction for a short period of time. And to better understand the dynamics of transmission of COVID-19, a second model which is a fuzzy model generalizes the first one, has been studied, and has given us more information, by comparing the obtained results with the real case, and also with that given by the model discussed in [21], we show the effectiveness of our proposed models.
