uine and tafenoquine. The guidance covers the use of these drugs for primary and terminal prophylaxis, as well as contraindications (e.g. G6PD deficiency, pregnancy, and psychiatric or cardiac conditions) and safety precautions for children and special populations. The aim is to help travellers and healthcare providers reduce the risk of malaria during travel.

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 artemisinin 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.

Combination therapy is a cornerstone of modern malaria treatment, particularly in the context of widespread multidrug resistance. Using two or more antimalarial drugs with different mechanisms simultaneously enhances efficacy, shortens treatment dur

ation, improves compliance and delays the development of resistance. Artemisinin-based combination therapies (ACTs), such as artemether–lumefantrine, artesunate–amodiaquine and artesunate–sulfadoxine/pyrimethamine, are highly effective in rapidly clearing parasites and reducing gametocyte carriage. They are also generally well tolerated. Non-artemisinin combinations, quinine-based regimens and novel combinations (e.g. piperaquine–dihydroartemisinin) offer alternative therapeutic options, although clinical experience with these remains limited. Although ACTs are the preferred first-line treatment, factors such as cost, local drug resistance patterns, safety during pregnancy and paediatric use must inform implementation and policy decisions.

The twentieth century ended with human African trypanosomiasis (HAT) epidemics raging across many parts of Africa. Resistance to existing drugs was emerging, and many programs aiming to contain the disease had ground to a halt, given previous succes

s against HAT and the competing priorities associated with other medical crises ravaging the continent. A series of dedicated interventions and the introduction of innovative routes to develop drugs, involving Product Development Partnerships, has led to a dramatic turnaround in the fight against HAT caused by Trypanosoma brucei gambiense. The World Health Organization have been able to optimize the use of existing tools to monitor and intervene in the disease. A promising new oral medication for stage 1 HAT, pafuramidine maleate, ultimately failed due to unforeseen toxicity issues. However, the clinical trials for this compound demonstrated the possibility of conducting such trials in the resource-poor settings of rural Africa.
