The discovery of molecular markers of resistance in the Kelch 13 gene gives us the unusual opportunity to monitor the emergence and spread of resistance nearly in real time. Assessing the prevalence of these molecular markers in other regions can provide an early warning system to trigger rapid responses to develop control strategies.
The ART 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.
It is not yet known whether the prevalence of certain mutations necessarily means that parasites are clinically resistant. Rather, pins are coloured on the basis of currently agreed definitions within the research and policy community as follows:
