Malaria

Mapping tool on tracking biological challenges to malaria control and elimination

Last update: 31 October 2017

Malaria Threats Map

Malaria Threats Map is an online mapping platform released in beta version in October 2017. It presents simple maps that contain information from 3 WHO global databases on:

  • Anopheles spp. malaria vector insecticide resistance
  • P. falciparum hrp2/3 gene deletions
  • P. falciparum and P. vivax antimalarial drug efficacy and drug resistance

Features of the mapping platform include:

  • harmonized interface and linkage between the 3 data sets,
  • display of aggregate national data or individual site data,
  • geographies navigator to show data for a select region, subregion or country,
  • dynamic filters for selecting subsets of data, e.g. by year, vector species, deletion type, drug type,
  • pop ups to display graphs of national and site-specific data,
  • available in English, French and Spanish,
  • examples of platform utility and narrative that includes links to relevant WHO guidance.

The platform is best accessed from a desktop computer. An instructional video is under development.

Global databases

Vector insecticide resistance

The global database on vector insecticide resistance was established in 2014. It facilitates centralized data collection and standardized reporting on the status of insecticide susceptibility of Anopheles mosquitoes in malaria-endemic countries. The contents of the database have been extracted from published and non-published reports on insecticide bioassays conducted by national malaria control programmes and their partners, including research and academic institutes, and nongovernmental organizations.


P. falciparum hrp2/3 gene deletions

The global database on P. falciparum hrp2/3 gene deletions was established in 2017 based on a review of published and unpublished reports. A centralized data repository will help to accelerate our understanding of the geographical distribution of pfhrp2/3 gene deletions and how this evolves over time.


Antimalarial drug efficacy and drug resistance

The global database on antimalarial drug efficacy and resistance was initiated in 2000 to centralize data and facilitate reporting on the status of antimalarial drug efficacy in malaria endemic countries. The contents of the database are extracted from published and non-published therapeutic efficacy studies (TES) conducted by ministries of health, national malaria control programmes, research institutes and nongovernmental organizations.

More recently, the database has been extended to include data from studies of molecular markers PfKelch 13, Pfplasmepsin 2-3, Pfmdr1, Pfcytochrome b and Pfcrt in Mesoamerica. The malaria threat maps currently include data from studies conducted on K13, and the maps will be further developed in 2018 to show data on the Pfcrt molecular marker.
