    About This Calculator

    Artemisinin-based combination therapies (ACTs) are the WHO-recommended first-line treatment for uncomplicated Plasmodium falciparum malaria. Weight-based dosing is critical especially in children, where under- or over-dosing affects both efficacy and safety. Artemether-lumefantrine (Coartem) is the most widely used ACT across sub-Saharan Africa, while DHA-piperaquine (Eurartesim) is increasingly adopted in East Africa and parts of South Asia. This calculator reflects WHO 2022 malaria treatment guidelines and country-specific national protocols for Nigeria, Kenya, Ghana, Uganda, Tanzania and India. Always verify your country's current first-line recommendation — protocols may change with regional resistance surveillance data.
