In November 2022, WHO launched a strategy to address antimalarial drug resistance in Africa, emphasizing the need for stronger surveillance. While regional monitoring networks have been active in other regions, most in Africa have not convened since 2017–2018. To renew collaboration, WHO organized... a meeting bringing together countries from the African and Eastern Mediterranean regions. Participants shared recent data on antimalarial efficacy and resistance. While artemisinin-based combination therapies remain highly effective, some sites in Uganda and the United Republic of Tanzania reported lower-than-expected efficacy of artemether–lumefantrine. Delayed parasite clearance linked to Plasmodium falciparum Kelch-13 mutations was noted in Eritrea, Rwanda, Uganda and the United Republic of Tanzania. Discussions highlighted challenges in therapeutic efficacy studies, molecular marker surveillance and the need for improved genotyping to distinguish relapses from new infections.

Découverte par Alphonse Laveran en 1880, cette maladie parasitaire demeure en 2022 l’endémie la plus répandue dans les régions tropicales et subtropicales. Selon le rapport mondial sur le paludisme de 2021 de l'OMS, on estime à 232 millions le nombre de cas en 2019 dans 87 pays endémiques, d...ont 94 % sont concentrés en Afrique subsaharienne et sont principalement dus à Plasmodium falciparum. Le nombre de décès est passé de 897 000 en 2000 à 568 000 en 2019, dont près de 95 % sont survenus dans 31 pays. Des baisses marquées sont également observées en Asie du Sud-Est. Avec des financements suffisants et un renforcement des campagnes d'information, le contrôle, voire l'éradication du paludisme, restent envisageables.

Antimalarial chemotherapy is crucial for reducing morbidity, mortality, and drug resistance, and is the cornerstone of malaria control. Existing antimalarial drugs act at different stages of the parasite’s life cycle. These drugs range from classic agents such as chloroquine and quinine to newer a...rtemisinin derivatives. They include tissue schizonticides, blood schizonticides, gametocytocides, and sporontocides. Artemisinin and its derivatives are the most effective and fastest-acting treatment against drug-resistant Plasmodium falciparum, achieving rapid parasite clearance and reducing transmission potential. Other key drugs include mefloquine, halofantrine, proguanil, sulfadoxine–pyrimethamine, atovaquone–proguanil, tetracyclines, clindamycin and azithromycin. Each of these drugs has a specific mechanism of action, pharmacokinetics, efficacy, safety profile and contraindications. Rational drug combinations and adherence to national treatment guidelines are essential for managing resistance, ensuring safety in vulnerable populations such as children and pregnant women, and optimising therapeutic outcomes in cases of both uncomplicated and severe malaria.

To mark the International Day of the African Child, Medicines for Malaria Venture (MMV) celebrated the inclusion of three of its antimalarial medicines on the WHO Model List of Essential Medicines (EML) and the EML for Children (EMLc). These are two artemisinin-based combination therapies (ACTs) for... adults, children and infants, and a rectal artesunate formulation for the pre-referral treatment of severe malaria in young children. The approved therapies — pyronaridine–artesunate, dihydroartemisinin–piperaquine and rectal artesunate — offer child-friendly formulations and are the first-line treatment for uncomplicated malaria caused by Plasmodium falciparum and P. vivax. Inclusion in the EMLc facilitates national adoption, improves access to high-quality treatments and addresses the disproportionate malaria burden among children under five. This supports global efforts to reduce malaria mortality and advance elimination.

This technical note provides guidance on actions to accelerate P. falciparum elimination in areas close to achieving this goal without compromising unified malaria elimination efforts (P. vivax - P. falciparum), while contributing to the country's ultimate goal of eliminating malaria overall.
Relapsing malaria caused by Plasmodium vivax parasites poses a significant challenge to global malaria elimination efforts. About one third of the population remains at risk of contracting P. vivax malaria, and 85% of P. vivax infections stem from reactivated latent parasites, leading to chronic ana...emia and increased morbidity and mortality. In addition to diagnostic tools that can detect the acute, blood-stage of P. vivax, new tools are needed to detect the dormant infections before they reactivate and contribute to morbidity and onwards transmission

High levels of storage iron may increase malaria susceptibility. This risk has not been investigated in semi-immune adolescents. We investigated whether baseline iron status of nonpregnant adolescent girls living in a high malaria transmission area in Burkina Faso affected malaria risk during the fo...llowing rainy season. For this prospective study, we analysed data from an interim safety survey, conducted six months into a randomised iron supplementation trial. We used logistic regression to model the risk of P. falciparum infection prevalence by microscopy, the pre-specified interim safety outcome, in relation to iron status, nutritional indicators and menarche assessed at recruitment.

This report, published in conjunction with a summary overview of results of rounds 1–8, is the eighth and final report in a series of laboratory-based evaluations of rapid diagnostic tests (RDTs) for malaria. It provides a comparative measure of their performance in a standardized way to distingui...sh between well and poorly performing tests.
These results constitute the laboratory evaluation component of the WHO prequalification process for malaria RDTs and inform the current WHO procurement recommendations. In round 8, 35 RDTs from 17 manufacturers were assessed. For the first time the evaluation included an assessment of product performance against a panel of P. falciparum parasites with pfhrp2/3 gene deletions and therefore not expressing HRP2.

The 2022 report reviews the global malaria diagnostics market and technological landscape to support Unitaid’s 2023–2027 strategy for quality malaria case management. The report highlights the stalled progress of malaria control efforts, the gaps in access to diagnostics and the public health im...plications of P. falciparum HRP2/3 gene deletions, which compromise the accuracy of the widely used HRP2-detecting rapid diagnostic tests (RDTs). The report analyses the malaria RDT market, noting supplier diversification, price trends and production shifts resulting from the pandemic. It also addresses the emerging point-of-care G6PD testing market, which is required to ensure the safe radical cure of P. vivax infections. It surveys technological innovation, including digital microscopy, hemozoin tests, nucleic acid detection and biosensors, while emphasising that RDTs and microscopy will remain the mainstay of case management in the near term. The report identifies market shortcomings, access barriers and opportunities to improve malaria case management and diagnostic coverage.
