Evolving patterns of drug resistance, exemplified most recently by reports of artemisin resistance in Southeast Asia,1 require periodic review of chemoprophylaxis recommendations for travellers.
The scope of this review is the prevention of Plasmodium falciparum, which is the malaria species that causes the overwhelming majority of severe disease and death, and which in many areas of the world is frequently resistant to the classical antimalarial agent chloroquine. This review further focuses on the non-immune traveller without prior malaria exposure, who has a …
