Making the most of malaria chemoprevention.

Against a backdrop of stalled progress in malaria control, it is surprising that the various forms of malaria chemoprevention are not more widely used. The World Health Organization (WHO) has recommended several malaria chemoprevention strategies, some of them for over a decade, and each with documented efficacy and cost effectiveness. In 2022, the WHO updated and augmented its malaria chemoprevention guidelines to facilitate their wider use. This paper considers new insights into the empirical evidence that supports the broader application of chemoprevention and encourages its application as a default strategy for young children living in moderate to high transmission settings given their high risk of severe disease and death. Chemoprevention is an effective medium-term strategy with potential benefits far outweighing costs. There is a strong argument for urgently increasing malaria chemoprevention in endemic countries.
