aThe number of positive cases is corrected for blood sample volume using a correction factor of 1.15 for 100 μL and 60 μL samples and 1.95 for 20 μL samples30.
bThere is some uncertainty regarding the dominant vector species in Kwemwale/Nkumba, Tanzania. In addition to C. quinquefasciatus, both Anopheles gambaie s.l. and An.funestus have been cited as vectors responsible for transmission around Tanga and Muheza57, 58.
cThe survey year was given by reference59.
