Patients with suspected malaria should have parasitological confirmation of diagnosis with either microscopy or rapid diagnostic test (RDT) before antimalarial treatment is started. Treatment based on clinical grounds should only be given if diagnostic testing is not immediately accessible within 2 hours of patients presenting for treatment.

For P. falciparum infections acquired in areas without chloroquine-resistant strains, which include Central America west of the Panama Canal, Haiti, and the Dominican Republic, patients can be treated with oral chloroquine. Artemisinin-based combination therapy ACT is effective against blood-stage P. vivax but requires co-administration with primaquine to achieve radical cure. The therapeutic efficacy of primaquine depends on the generation of a therapeutically active metabolite via cytochrome P450 2D6 CYP2D6. Artemisinin-based combination therapy ACT is emerging as the best option in this context, particularly in settings where there are concerns about chloroquine-resistant P. vivax. ACT is effective against the blood stage of P. vivax 9, but must be co-administered with primaquine to eliminate P. vivax hypnozoites 8, 10. Malaria and, as no alternative to artemisinin derivatives is expected to enter the market for several years, their efficacy must be preserved. Prompt treatment – within 24 hours of fever onset – with an effective and safe antimalarial is necessary to effect a cure and prevent life-threatening complications.

Artemisinin-based combination therapy ACT is recommended by WHO for the treatment of uncomplicated falciparum malaria. 1 The success of this recent policy change will depend on the efficacy of the combination components, high population coverage, low costs, correct dosing, and ensuring good adherence to prescribed treatment.

Falciparum with chloroquine due to having separate treatment strategies? If a unified treatment strategy was seen as desirable, which artemisinin-based combination would be the most appropriate for use in co-endemic settings? What are the operational benefits and disadvantages of a unified versus a separate treatment strategy in co-endemic regions? Artemisinin Combination Therapies are currently the frontline treatments against Plasmodium falciparum malaria. Although these treatments are working well in many parts of the world, there is serious concern that malaria parasites are once again developing widespread resistance to this vital treatment. In some parts of Oceania the P. vivax parasite in now highly resistant to chloroquine, which makes this treatment ineffective. Artemisinin‐based combination therapies ACTs are now the recommended treatment for P. falciparum malaria worldwide. As the effectiveness of chloroquine for P. vivax declines, alternative therapies are needed.
