Chloroquine has been extensively used in mass drug administrations, which may have contributed to the emergence and spread of resistance. It is recommended to check if chloroquine is still effective in the region prior to using it.

Spread of malaria to new areas and re-emergence of malaria in areas where the disease had been eradi-cated. Drug resistance has also played a significant role in the occurrence and severity of epidemics in some parts of the world. Population movement has introduced resistant parasites to areas previously free of drug resistance. The economics. The location of study sites with documented chloroquine resistance and chloroquine sensitive P. vivax is shown in Figure 2a and for chloroquine sensitive sites in Figure 2b below. Estimates for chloroquine sensitivity derived from 112 sites. In 50.9% of the sites estimates P. vivax were categorized as resistant. The Centers for Disease Control and Prevention recommend against treatment of malaria with chloroquine alone due to more effective combinations. In areas where resistance is present, other antimalarials, such as mefloquine or atovaquone, may be used instead.

The risk of acquiring chloroquine resistant P. falciparum malaria CRPF is another consideration. Malaria Prophylaxis – Malaria Site. Chloroquine resistant Plasmodium vivax review Worldwide Antimalarial.. Malaria Prophylaxis. The ABCD of Malaria Prophylaxis. Patient. Oct 04, 2002 Plasmodium falciparum chloroquine resistance is a major cause of worldwide increases in malaria mortality and morbidity. Recent laboratory and clinical studies have associated chloroquine resistance with point mutations in the gene pfcrt. However, direct proof of a causal relationship has remained elusive and most models have posited a. Chloroquine shouldn’t be used for treatment of P. falciparum infections from areas of chloroquine resistance or malaria occurring in patients where chloroquine prophylaxis has failed. Despite the growing stories due to resistance of parasite to chloroquine in some parts of the world. this drug remains one of the most widespread to malaria. 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.
