Fig 3. Model projections of annual MDA treatment of 85% school-aged children (SAC; 5–14 years of age) and 40% adults (15+ years of age).

Shown for high prevalence settings (≥50% SAC baseline prevalence). The shaded areas (both blue and red) represent the 90% credible interval. Graph (A) shows the prevalence of heavy-intensity infections in school-aged children (SAC) and adults. Graph (B) represents the probability of reaching the WHO goals by year 15.
