P. falciparum = Asexual forms; Gametocytes = Sexual forms only for P. falciparum; Mixed infection = Concomitant presence of P. falciparum and P. malariae; Parasite Density = Geometric mean parasite density only for P. falciparum, after log10 transformation (expressed as asexual parasites/μl; Fever = Axillary temperature ≥ 37.5°C; Fever & Parasites = Fever associated with one or more asexual forms of P. falciparum parasites; Anaemia = Haemoglobin < 11 g/dl.

NB.: All point prevalence are mean estimation adjusted for stratification, clustering and design effect.
