Before revision:  It has been widely used to model other epidemics such as Ebola, MERS (Middle East Respiratory Syndrome) , and influenza . Ageneral SEIR model represents an epidemic using four compartments in cascade; susceptible (S), exposed (E), infected (I), and recovery/removed (R), where the model assumes that the epidemic exits with the infected population either recovered or removed due to immunity to the virus. In this work, we present a modified SEIRS model with additional exit conditions in the form of death rates and resusceptibiliy, where we tuned the exit conditions in the model to extend predictions on the projection of the current pandemic into three  outcomes;
