    “Presumptive treatment” without the benefit of laboratory confirmation should be reserved for extreme circumstances (strong clinical suspicion or severe disease in a setting where prompt laboratory diagnosis is not available). Once the diagnosis of malaria has been made, appropriate antimalarial treatment must be initiated immediately.

Resistance developed by most parasites that were initially sensitive to drugs mostly result from mutations in the genes responsive to the drug. P. falciparum or Species Not Identified – Acquired in Areas Without Chloroquine Resistance. 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.

Patients infected with a resistant strains of plasmodia should be treated with another antimalarial drug. The parasite Plasmodium falciparum, like neoplastic cells, develops resistance to multiple structurally unrelated drugs. If the mechanisms by which P. falciparum and neoplastic cells become resistant are similar, then it may be possible to reverse the resistance in the two types of cells by the same pharmacological agents. Verapamil, a calcium channel blocker, completely reversed chloroquine. We evaluated 2 drug resistance markers, the P. falciparum chloroquine resistance transporter pfcrt gene and the artemisinin resistance gene Kelch 13 k13, in malaria parasites in Haiti to determine prevalences and provide information and recommendations for clinical practice to support malaria elimination efforts.
