The reports bring together the latest findings and conclusions about the state of resistance to artemisinins and artemisinin-based combination therapy (ACT), summarize WHO’s current policy and treatment recommendations, and highlight areas of concern.
Efficacious antimalarial medicines are critical to malaria control and elimination. Continuous monitoring of their efficacy is needed to inform treatment policies in malaria-endemic countries, and to ensure early detection of, and response to, drug resistance.
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.

All malaria-endemic countries in the Region of the Americas have taken on the challenge of eliminating malaria and have focused their health programs and strategies on that goal. The risk of emergence of artemisinin resistance in the Americas, the characteristics of P. falciparum parasite, and the e...pidemiological evidence of subnational territories experiencing reintroduction of P. falciparum urge for a call to push for P. falciparum elimination as an intermediate goal of the elimination of all malaria human species. Derived from the elimination of P. falciparum, other important results are expected, such as the empowerment of different actors and entities for the elimination of malaria inspired by the achievements of the elimination of P. falciparum, using early victories as a catalyst. 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. The acceleration of P. falciparum elimination has several goals: mitigating the risk that resistance to artemisinin and associated drugs will emerge and spread; accelerating the reduction in the total number of malaria cases in areas with a significant proportion of P. falciparum; accelerating malaria elimination (both P. vivax and P. falciparum), considering that P. falciparum is one of the triggers of P. vivax relapses; developing capacities in interventions to accelerate malaria elimination by building on the experience of P. falciparum elimination; and empowering different actors, including high-level authorities, donors, municipalities, and other entities involved in malaria elimination, by inspiring them with the achievements of P. falciparum elimination.

These guidelines are based on the 3rd Edition of the WHO Guidelines (Published 2015) World Health Organization’s Guidelines for the treatment of malaria. Additional literature surveys have been undertaken. Factors that were considered in the choice of therapeutic options included effectiveness, sa...fety, and impact on malaria transmission and on the emergence and spread of antimalarial drug resistance. On-going surveillance is critical given the spread of artemisinin resistance in Southeast Asia, although not yet confirmed anywhere in Africa. The guidelines on the treatment of malaria in South Africa aim to facilitate effective, appropriate and timeous treatment of malaria, thereby reducing the burden of this disease in our communities. This is essential to further reduce the malaria case fatality rates currently recorded in South Africa, to decrease malaria transmission and to limit resistance to antimalarial drugs.

Malaria is a prevalent cause of febrile illnesses in areas with high transmission, and its clinical presentation overlaps with initial signs of Ebola disease. For this reason, the effectiveness of the Ebola response in Guinea, Liberia and Sierra Leone can be optimized through the deployment of targe...ted measures to reduce the number of fever cases due to malaria
WHO recommends specific adaptations in the diagnosis of malaria and in LLIN distribution in countries heavily affected by the Ebola outbreak and mass drug administration using artemisinin-based combination therapies (ACTs) in areas where transmission of both Ebola and malaria is high and access to malaria treatment is very low.
