  1. N number in counts, p/µl parasites per µl of blood, Min minimum, Max maximum, IQR interquartile range, PD parasite density
  2. The sites are listed with the number of study participants in brackets. The values in the table represent frequency as counts (N) and % in brackets of the total population at each site during each time point. Study participants were stratified into three age groups, ≤ 10 years, 11–15 years and ≥ 16 years. N number of people. Asexual parasite prevalence was detected by light microscopy and gametocyte prevalence by Pfs25 mRNA RT-PCR
