Percentage change in the projected numbers of positive, recovered and death cases as of September 26 due to the use of repurposing drug therapy with different control efficacies. The change is calculated with their corresponding values of August 27. It shows that the use of repurposing drugs will reduce the projected deaths by 2.39%, 4.93% and 7.51% when $u_3$ takes values 0.2, 0.3 and 0.4, respectively. Similar changes may be observed in the cumulative infected cases ($I_h+I_c$). An increase in the recovery class ($R$) is also observed and the percentage change is indicated by a positive sign.
