Fig 11. The numerical results of model (3) and (4) and model (9) and (10) by varying ϵ and applying the coverage of MDA data from the TUMIKIA community-based annual deworming control strategy.

(a) Disease persistence if ϵ < 0.73. (b) Disease extinction if ϵ ≥ 0.85. (c) Disease elimination is possible for model (3) and (4) if ϵ ≥ 0.73, but the disease will remain in endemic state for model (9) and (10) if ϵ < 0.85.
