  1. aThe epidemiology of malaria in the lowland and on the plateau was characterized based on the malaria stability index [28], which determines the rooting of the disease in a particular zone: i)- 0 < St < 0.5 for unstable malaria zones, ii)- 0.5 < St < 2.5 for intermediate zones of malaria stability, and iii)- St > 2.5 for stable malaria zones.
