Modelling the Transmission Dynamics of Meningitis among High and Low-Risk People in Ghana with Cost-Effectiveness Analysis

Figure 9

Effect of using both vaccination and treatment only. The control profile in (a) shows that for effective eradication of meningitis, vaccination must be applied to all individuals for 50 days while treatment is implemented for 48 days. The simulation result of the optimal control model shows the effectiveness of these measures on (b) carriers and (c) infected individuals. In the graphs, the solid line denotes without the strategy while dotted line indicates implementation of the control strategy.
