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

Figure 10

Effect of using both vaccination and personal protection only. The simulation results of the control profile in (a) show the effectiveness of this strategy. To eradicate meningitis, vaccination must be administered for all individuals throughout the period while personal protection is encouraged for at least 14 days during the period of infectiousness. The simulation result of the optimal control model shows the effectiveness of these measures on (b) carriers and (c) infected individuals. In the graphs, solid line denotes without control while dotted line indicates implementation of the controls.
