Artemisinin Molecular Surveyor

The Artemisinin Molecular Surveyor is an interactive map that summarises the prevalence of these molecular markers in the propeller region of the Kelch 13 gene of the malaria parasite by location and year, providing a clear and standardised visualisation of the evidence to date to inform key international, regional and national monitoring strategies.

• Displays the distribution of resistance markers found on the Plasmodium falciparum malaria parasite Kelch 13 gene according to their association with delayed parasite clearance:  
  • K13 mutations associated with slow parasite clearance (associated with slow clearance ticked)
  • All nonsynonymous K13 mutations (associated with slow clearance unticked)
• Displays data from 429 published studies, covering sites in 79 countries, from 2001 to February 2024
• Presents molecular analyses of K13 genotypes,
• Flexible default settings can be altered easily by the user,
• View countries with data on the left hand bar,
• Discover other visualisations of the same data that allow the user to explore the temporal trends and compare two different sites of interest in more detail are available below the map.
