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 total annual parasite index (API) of the last three years published by WHO in the Malaria world report. API reflects the number of confirmed new cases from malaria registered in a specific year, expressed per 1,000 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, Austria, the Netherlands en Belgium. 

Maps differentiating API for P. falciparum and API for P. vivax exist and can be accessed by professionals.
