The article introduces Pf-HaploAtlas, a new online tool developed by MalariaGEN to track genetic mutations in the Plasmodium falciparum parasite—the most deadly malaria-causing species. This app allows researchers and public health professionals to explore global data on drug resistance mutations and genetic variation across thousands of parasite genomes. The tool is designed to improve understanding of how malaria parasites evolve and spread, and to support efforts in monitoring antimalarial drug resistance. With an intuitive interface, Pf-HaploAtlas enables users to visualize haplotype patterns, compare regional differences, and access up-to-date data that can inform control strategies and research.
