The International Limits and Population at Risk of Plasmodium vivax Transmission in 2009

Figure 1

Flow chart of the various data and exclusion layers used to derive the final map.

The pink rectangle denotes the surface area and populations of PvMECs, whilst the pink ovoid represents the resulting trimmed surface area and PAR after the exclusion of risk by the various input layers, denoted by the blue rhomboids. Orange rectangles show area and PAR exclusions at each step to illustrate how these were reduced progressively. The sequence in which the exclusion layers are applied does not affect the final PAR estimates.
