Gambissara, The Gambia: spatial clustering of P. falciparum infection. a, b Rainy Seasons, 2012–2014. Household-level prevalence of P. falciparum infection was low (not detectable using the color-coded scale in the legend) in Gambissara Town, but readily detectable in the more rural area of western Gambissara. a for the western (rural) area of Gambissara in the rainy season is on the left side of Fig. 2; b Gambissara Town during the rainy season is on the right side of Fig. 2. c, d Dry Seasons, 2013–2015. As in the rainy season, the household-level prevalence of P. falciparum infection was undetectable in Gambissara Town. In contrast, households with P. falciparum infection were readily detectable in the more rural area of western Gambissara where housing is less secure and thatched roofs and mud walls provide less protection from anopheline vectors. c The western (rural) area of Gambissara in the dry season is on the left side of Fig. 2; d Gambissara Town in the dry season where better housing provided greater protection against Anopheles gambiae is on the right side of Fig. 2.
