  1. 95 % CI: 95 % confidence intervals
  2. aPeople who were sick, pregnant or breastfeeding were excluded from analysis
  3. bFour shehias were excluded from analysis due to problems with data obtained from the MoH (Upenja had duplicate, Miwani had invalid, and Gamba and Makoba had no MoH data)
  4. c21 schools were excluded from analysis. Reason: no MoH data were available for 19 schools in Unguja (among them, 13 schools also did not report any treatment in the post-MDA survey) and 2 additional schools, which reported no treatment in the post-MDA survey
  5. dTwo schools were excluded from analysis. Reason: no MoH data were available for the schools of two shehias in Pemba (Shungi and Mchanga Mdogo)
