The availability of epidemiologic data on drug-resistant malaria based on a standardized clinical and parasitological protocol is a prerequisite for a rational therapeutic strategy to control malaria. As part of the surveillance program on the therapeutic efficacy of the first-line (chloroquine and amodiaquine) and second-line (sulfadoxine-pyrimethamine) drugs for the management of uncomplicated Plasmodium falciparum infections, non-randomized studies were conducted in symptomatic children aged less than 10 years according to the World Health Organization protocol (14-day follow-up period) at 12 sentinel sites in Cameroon between 1999 and 2004.
