Mathematical Modeling of Transmission Dynamics and Optimal Control of Vaccination and Treatment for Hepatitis B Virus
Figure 2
Variation of different reproduction numbers by using of two control variables (vaccination and treatment). Figure 2 illustrates the impact of application of two controls (vaccination and treatment) on different basic reproduction numbers. , when there is no vaccination and treatment (; ). The figure shows that application of vaccination reduces more rapidly than treatment, though mixed intervention strategies always work better to reduce the disease burden.
