A global map of dominant malaria vectors

Area of Science:

• Malariology
• Medical Entomology
• Geographic Information Systems (GIS)

Background:

• Global malaria maps historically visualized vector distributions but often lacked comprehensive evidence.
• Previous mapping efforts were not consistently based on extensive, evidence-based approaches.

Purpose of the Study:

• To generate a novel global map of dominant malaria vector species (DVS).
• To utilize predicted distribution maps for individual species or complexes for enhanced accuracy.

Main Methods:

• Development of a global map integrating predicted distribution data for various Anopheles species.
• Leveraging contemporary, species-specific spatial occurrence data.

Main Results:

• The generated map illustrates significant spatial variability in vector dominance and complexity.
• In Africa, Anopheles gambiae, Anopheles arabiensis, and Anopheles funestus are frequently co-dominant.
• The Asian-Pacific region exhibits high complexity with multi-species coexistence and shifting dominance patterns.

Conclusions:

• The study discusses the effectiveness of the mapping methodology in accurately representing DVS distributions.
• A comprehensive, up-to-date database of species-specific spatial occurrence will be accessible via the Malaria Atlas Project (MAP) website.
