Graph showing the mean number of malaria cases per week diagnosed using malaria rapid diagnostic tests in a series of rural health centres in a section of the Choma and Namwala Districts in the Southern Province of Zambia. *The centres were segregated in two sections based on locality and elevation, as being in the "Kafue Flats" area (in, or close to the flood plain with elevation mainly below 1,100 m) and "Macha Heartland" (in slightly higher and drier area mainly above 1,100 m).
