      Malaria maps-background

      Latest update: - Authors: Ula Maniewski, Nele Alders

      What is the aim?

      Malaria maps are created to visualize the  malaria risk in different regions and should be used in combination with the detailed descriptions of the malaria regions mentioned per country.

      How are malaria maps created?

      The malaria maps are created based on the worst case scenario of the Annual Falciparum Incidence (AFI) and Annual Vivax Incidence (AVI) of the last three years published by WHO in the Malaria world report. These incidences reflect the number of autochthonous confirmed new cases from malaria registered in a specific year, expressed per 1000 individuals under surveillance for a geographic area.
      With these figures rough malaria maps are created, and then finetuned. This process is done in collaboration with the authorities/working groups making pretravel guidelines of Swiss, Germany, the Netherlands and Belgium.
