Vivax Surveyor

Discover an interactive online tool that displays Plasmodium vivax antimalarial clinical trials and the prevalence of chloroquine resistance in P. vivax parasites across the world, and through time.

The Vivax Surveyor is an interactive map that summarises the prevalence of Plasmodium vivax antimalarial clinical trials across the world. This tool provides a clear and standardised visualisation of vivax clinical trials to date to inform key international, regional and national monitoring strategies.
