Age-specific geometric mean of Plasmodium falciparum density (asexual parasites/μl) in the villages of Magoda (A) and Mpapayu (B) between 1999 and 2012. Data of under-fives from Mpapayu village (B) in 2010 and 2011 were excluded from the analysis because individuals seen were few and had high parasite density (4 with geometric mean parasite density of 21,744 and one participant with 31,200 asexual parasites/μl, respectively). In Mpapayu, no study participant aged <5 years old had malaria parasites in 2012.
