Ethiopia’s Growing Malaria Drug Resistance Posing Threat to Frontline Treatment, Study Finds
A nationwide genomic surveillance study has identified widespread antimalarial drug-resistance markers in Ethiopia, including mutations associated with partial resistance to artemisinin, raising concerns over the continued effectiveness of the country’s primary malaria treatment, according to reporting carried by AllAfrica.
The research, summarised by Addis Standard, detected genetic markers linked to reduced sensitivity to artemether-lumefantrine, the first-line therapy for Plasmodium falciparum malaria in Ethiopia. Artemisinin-based combination therapies have served as the global standard of care for uncomplicated falciparum malaria for two decades, and the emergence of partial resistance on the African continent has been closely watched by public health authorities.
Ethiopia remains one of the African countries with a significant malaria burden, with transmission patterns varying across its highland and lowland regions. The identification of resistance markers at a national scale suggests the mutations may already be circulating more widely than previously documented, which could complicate efforts to control the disease.
Artemether-lumefantrine is the most widely used antimalarial in sub-Saharan Africa. Health agencies have warned that the spread of resistance could erode treatment efficacy, force costly switches to alternative drug regimens, and reverse recent gains in malaria control. Genomic surveillance has become a central tool for tracking the evolution of resistance and guiding national treatment policy.
The findings come as several African countries report increasing detection of artemisinin partial-resistance markers, underscoring the need for sustained investment in surveillance, new therapeutics, and vector control. Ethiopian health authorities and international partners are expected to weigh the study’s implications for future treatment guidelines.
