Outcomes
Primary outcome [1] 262442 0
Treatment outcomes will be classified on the basis of an assessment of the parasitological and clinical outcome of antimalarial treatment according to the latest World Health Organization (WHO) guidelines.

Day 1, 2, 3, 7, 14, 21, 28, 35 and 42 for the treatment of uncomplicated falciparum malaria by artesunate+mefloquine
Secondary outcome [1] 273789 0
The incidence of any adverse event such as nausea, vomiting, diarrhea, etc. will be documented. All patients will be asked routinely about the previous symptoms and about symptoms that have emerged since the previous follow-up visit.
