Malaria remains an overwhelming problem in Africa, where about 90% of global malaria morbidity and mortality occur. 1 In most of sub-Saharan Africa, the majority of cases are caused by Plasmodium falciparum, the most virulent human malaria parasite, and the parasite with the greatest likelihood of drug resistance. Chloroquine-resistant P. vivax malaria was first identified in 1989 among Australians living in or traveling to Papua New Guinea. P. vivax resistance to chloroquine has also now been identified in Southeast Asia, Ethiopia, and Madagascar. Isolated reports have suggested chloroquine-resistance P. vivax in other countries and regions, but further evaluation is needed. These trials showed that chloroquine eliminated malaria and was appropriate to be used as an antimalarial drug.

While chloroquine-resistant malaria was rapidly outcompeted after the removal of chloroquine as the first-line treatment in Malawi, a similar return of chloroquine-susceptible infections has not been observed in Asia. The uniqueness of this phenomenon in Africa, but not in Asia, is likely multi-factorial. The forest zone of West Africa has a high risk of falciparum malaria throughout the year. Chloroquine-resistant parasites are widespread but their distribution is still patchy.
