Before revision:  From our simulation results, we observed that, SIR model with optimal control strategies shows a significant decrease in the proportions of infected and susceptible individuals and a rapid increase in the recovered individuals compared to SIR model without optimal control. A similar effect was observed in the SEIR model with control strategies. Following the numerical solutions , we can conclude that, effective educational campaigns and vaccination of susceptible individuals as were as effective treatments of infected individuals can help reduce the disease transmission.
After revision:  From our numerical illustrations , we can conclude that, effective educational campaigns and vaccination of susceptible individuals as were as effective treatments of infected individuals can help reduce the disease transmission.
