Despite the fact that emergence of chloroquineCQ resistant P.vivax isolates are reported from different parts of the world 8,9,10. Drug-resistant P. falciparum. Chloroquine-resistant P. falciparum first developed independently in three to four areas in Southeast Asia, Oceania, and South America in the late 1950s and early 1960s. Since then, chloroquine resistance has spread to nearly all areas of the world where falciparum malaria is transmitted.
