Reassessment of areas with persistent Lymphatic Filariasis nine years after cessation of mass drug administration in Sri Lanka
Fig 2
Distribution of households and mosquito collection sites tested for filariasis in Kalutara North (A), Ambalangoda (B), Unawatuna (C) and Weligama (D) PHI areas. Blue open circles indicate households (HH) where all tested residents had negative filarial antigen tests; Solid blue circles indicate houses with at least one resident with a positive filarial antigen test. Trap sites with no mosquito pools positive for filarial DNA are shown with open red circles, and trap sites with one or more positive mosquito pools are shown with solid red circles. Relatively few CFA positive households were identified, whereas there were many positive mosquito trap locations (especially in PHIs located in Galle and Matara districts).
