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

Figure 5

The global spatial limits of Plasmodium vivax malaria transmission in 2009.

Risk areas are defined as in Figure 2. The medical intelligence and predicted Duffy negativity layers are overlaid on the P. vivax limits of transmission as defined by the PvAPI data and biological mask layers. Areas where Duffy negativity prevalence was estimated as ≥90% are hatched, indicating where PAR estimates were modulated most significantly by the presence of this genetic trait.
