The WHO recommends parenteral artesunate over quinine and artemether for treating severe Plasmodium falciparum malaria in adults and children. Intravenous administration is preferred. A new one-step, arginine-based formulation eliminates the need for dilution steps, reducing errors and accelerating ...the initiation of treatment—a critical factor for survival. This formulation was first prequalified by the WHO in 2023. By contrast, the conventional two-step artesunate formulation, which was prequalified in 2010, requires more complex preparation. Clear guidance is essential, as product-specific protocols differ. These training materials aim to support the correct and effective administration of the medication.

The Strategy to respond to antimalarial drug resistance in Africa is a technical and advocacy document, grounded in the best available evidence to date and aimed at minimizing the threat and impact of antimalarial drug resistance of Plasmodium falciparum parasites in Africa. Its objectives are to: i...) improve the detection of resistance to ensure a timely response; ii) delay the emergence of resistance to artemisinin and artemisinin-based combination therapy (ACT) partner drugs; and iii) limit the selection and spread of resistant parasites where resistance has been confirmed.

La Stratégie de riposte face à la résistance aux antipaludiques en Afrique est un document technique de sensibilisation qui se fonde sur les bases factuelles les plus solides dont on dispose et vise à réduire au maximum la menace et l’impact de la résistance aux antipaludiques de Plasmodium ...falciparum en Afrique. Elle a pour objectifs i) d’améliorer la détection de la résistance et d’assurer une riposte en temps utile ; ii) de retarder l’émergence de la résistance à l’artémisinine et aux médicaments associés utilisés dans les combinaisons thérapeutiques à base d’artémisinine (CTA) ; et iii) de freiner la sélection et la propagation des parasites résistants là où une pharmacorésistance est confirmée. Si la Stratégie cible l’Afrique, il convient de noter que la
menace de la résistance aux antipaludiques concerne tous les pays d’endémie palustre et que les interventions proposées dans le présent document sont applicables dans d’autres régions géographiques à condition d’être adaptées aux spécificités locales.

Malaria in pregnancy is a significant health problem in malaria-endemic areas. It not only causes substantial childhood morbidity and mortality but also increases the risks of adverse events for pregnant women and their developing fetuses. Most of the burden in these areas is due to infection with P...lasmodium falciparum. Artemisinin-based combination therapy (ACT) has been recommended as first-line treatment for uncomplicated P. falciparum malaria in all populations, including pregnant women in their second and third trimesters, since 2006. However, for women in their first trimester of pregnancy, WHO recommended as first-line treatment a combination of quinine and clindamycin.
Based on a review of the evidence conducted in 2022, WHO now recommends artemether–lumefantrine, the ACT with the most human safety data available, as the preferred treatment for uncomplicated P. falciparum malaria in the first trimester of pregnancy. This document presents all relevant evidence on the effects and safety in early pregnancy of artemisinins and partner medicines used in ACTs from both studies in experimental animals and observational studies in humans.

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.

The WHO Malaria Threats Map is an interactive online platform that showcases the latest global data on four critical biological threats to effective malaria control and elimination: mosquito insecticide resistance, Plasmodium falciparum hrp2/3 gene deletions, antimalarial drug resistance, and the ...spread of invasive vector species. Designed for public health professionals and researchers, the map allows users to explore and filter data regionally, track emerging resistance patterns, and view visual trends. Its purpose is to inform strategies for surveillance, guide policy-making, and support efforts to eliminate malaria, particularly by anticipating and responding to biological challenges that could undermine control programs.

Background: The last decade has seen a dramatic increase in international and domestic funding for malaria control, coupled with important declines in malaria incidence and mortality in some regions of the world. As the ongoing climate of financial uncertainty places strains on investment in global ...health, there is an increasing need to audit the origin, recipients and geographical distribution of funding for malaria control relative to populations at risk of the disease. Methods: A comprehensive review of malaria control funding from international donors, bilateral sources and national governments was undertaken to reconstruct total funding by country for each year 2006 to 2010. Regions at risk from Plasmodium falciparum and/or Plasmodium vivax transmission were identified using global risk maps for 2010 and funding was assessed relative to populations at risk. Those nations with unequal funding relative to a regional average were identified and potential explanations highlighted, such as differences in national policies, government inaction or donor neglect.

Schistosomiasis and soil-transmitted helminths (STH) infections are major public health problems. We aimed to study the 6-mo impact of mass drug administration with praziquantel and albendazole on urinary schistosomiasis and STH.We examined children (aged 2–15 y) from one hamlet, who provided urin...e and faeces samples at baseline (n=197), 1 mo (n=102) and 6 mo (n=92); 67 completed the protocol.At baseline, 47/67 (70.1%) children presented Schistosoma haematobium (75.8% in the baseline total sample) and 12/67 (17.9%) with STH (30.5% in the initial sample, p=0.010). Among the children, 47.3% had heavy Schistosoma haematobium infection. The most frequent STH was Trichuris trichiura in 9.0%. We also found Hymenolepis nana (13.2%) and Plasmodium falciparum (9.1%) infections and anaemia (82.1%). One mo after chemotherapy there was a significant (p=0.013) reduction of Schistosoma haematobium prevalence (23.5%) and a high egg reduction rate (86.9%). Considering the sample of 67 children, the mean egg concentration was 498 at baseline, 65 at 1 mo and 252 at 6 mo (p<0.05). We also observed a reduction in STH infections, 50% in Ascaris lumbricoides, 33.3% in T. trichiura and 50% in hookworms. At 6 mo, the prevalence of Schistosoma haematobium (76.1%) was similar to the baseline and the STH reduction was not significant.Longitudinal studies have reported many losses in these settings, but we were able to show that mass drug administration for control of schistosomiasis and STH present low effectiveness, that reinfections occur rapidly and that stand alone anthelmintic therapy is not a sustainable choice.
