Malaria endemicity, its stratification and time-lines for action phases of the global malaria eradication programme (GMEP). The schematic derives details of the phase, approximate timings, action stage and activity of the GMEP1-3, 5 and integrates these with malaria endemicity classifications defined by the host prevalence12, 13, vector stability indices29 and the basic reproductive number (see Supplementary Information SI).42 The year row presents an estimate of the duration of each phase (optimistic scenario-pessimistic scenario). PR: parasite rate, PfPR: Plasmodium falciparum parasite rate, Ro: basic reproductive number, API: annual parasite incidence, IRS: indoor residual spraying, RxCQ: radical treatment with chloroquine, IT: interruption of transmission.
