Although chloroquine-resistant P. falciparum predominates in Africa, it is found in combination with chloroquine-sensitive P. vivax malaria in South America and Asia. Resistance of P. vivax to chloroquine has been confirmed only in Papua New Guinea and Indonesia. For destinations where any chloroquine-resistant malaria is present, in addition. Abstract. The development of chloroquine as an antimalarial drug and the subsequent evolution of drug-resistant Plasmodium strains had major impacts on global public health in the 20th century. In P. falciparum the cause of the most lethal human malaria, chloroquine resistance is linked to multiple mutations in PfCRT, a protein that likely functions as a transporter in the parasite’s.
