Fig 2. Coverage levels required to meet the World Health Organization (WHO) goals.
Levels of school-aged children (SAC; 5–14 years of age) and adult (≥ 15 years of age) coverage required to meet the WHO goals when following currently recommended WHO treatment frequencies, i.e. for moderate baseline prevalence in SAC, treating once every 2 years; for high baseline prevalence in SAC, treating once a year. Required coverage levels are shown for a 5, 10 and 15-year treatment programme within low, moderate and high adult burden of infection settings. NA: not achievable unless SAC coverage is increased above 75%. More detailed S1–S3 Tables.
