aChildren ≤ 15 years, adults 16 years + .
bAll samples < 2 HhaI copies/μl were considered PCR negative (detection limit), all samples < 53 HhaI copies/μl were considered as not infected.
cFor logistic reasons blood was collected during daytime in 2 villages, therefore Mf counts are absent.
dMf prevalence in the 3-year residents could be determined in 20 individuals only.
