Fig 4. Model projections of MDA treatment of 75% school-aged children (SAC; 5–14 years of age) in moderate baseline transmission settings.

Fig 4

The blue line shows the impact of MDA programme assuming that there is no acquired immunity present. The red line shows the impact of MDA programme assuming that there is acquired immunity present with δ = 0.001. The green line shows the impact of MDA programme assuming that there is acquired immunity present with δ = 0.002. The purple line shows the impact of MDA programme assuming that there is acquired immunity present with δ = 0.003. The model was fitted to data for each value of δ.
