Fig. 6From: Dramatic decreases of malaria transmission intensities in Ifakara, south-eastern Tanzania since early 2000sMap showing distribution of a An. arabiensis and b An. funestus within the five wards of Ifakara town. All clusters depicting areas with households where the highest densities are most spatially concentrated were first identified, after which statistically significant ones were determined at level of Gi* P value ≤ 0.05, and Gi* Z score ≥ 1.96. The actual Getis-Ord Gi* statistics are provided to illustrate areas with maximum and minimum vector densitiesBack to article page
