摘要

Resistance to many antimalaria drugs developed on the Cambodia–Thailand border long before develop-ing elsewhere. Because antimalaria resistance is now a global problem, artemisinin-based combination therapies (ACTs) are the fi rst-line therapies in most malaria-endemic countries. However, recent clinical and molecular studies suggest the emergence of ACT-resistant Plasmodium fal-ciparum infections in the Cambodia–Thailand border area, where standard ACT is artesunate and me. oquine. These ACT failures might be caused by high-level me. oquine re-sistance because me. oquine was used for monotherapy long before the introduction of ACT. This observation raises 2 questions. First, how can existing P. falciparum–resistant strains be controlled. Second, how can the evolution of new ACT- resistant strains be avoided elsewhere, e.g., in Africa. Enforcement of rational drug use and improved diagnostic capacity are among the measures needed to avoid and con-tain ACT resistance
