Table 3. Number of years to achieve the goal (with a probability >0.8) for moderate and high transmission settings (acquired immunity is assumed to be present).

MDA is administrated for 15 years.

Target goal	Low to Moderate transmission settings	High transmission settings
Morbidity control	Baseline SAC prevalence <40%: 2–10 years Baseline SAC prevalence >40%: Not achieved	Baseline SAC prevalence <57%: 11–14 years Baseline SAC prevalence >57%: Not achieved
EPHP	Baseline SAC prevalence <15%: 14 years Baseline SAC prevalence > 15%: Not achieved	Not achieved
