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.

Drug resistance is the ability of a parasite to survive despite the presence of a drug that is meant to kill it in toxic levels. Resistance developed by most parasites that were initially sensitive to drugs mostly result from mutations in the genes responsive to the drug. This naturally occurring genus of bacteria infects many species of insects, including mosquitoes. The reason this is important is that Wolbachia-infected mosquitoes become resistant to the parasite Plasmodium falciparum, which causes some 219 million cases of malaria worldwide and more than 660,000 deaths. Malaria is a potentially life‑threatening tropical disease caused by Plasmodium parasites, which are transmitted through the bite of an infected female Anophel Malaria – Knowledge for medical students and physicians 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.

To determine whether withdrawal of chloroquine can lead to the reemergence of chloroquine sensitivity, the prevalence of the pfcrt 76T molecular marker for chloroquine-resistant Plasmodium falciparum malaria was retrospectively measured in Blantyre, Malawi. 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. Chloroquine remains the treatment of choice for vivax malaria,3 except in Indonesia's Irian Jaya Western New Guinea region and the geographically contiguous Papua New Guinea, where chloroquine resistance is common up to 20% resistance. Chloroquine resistance is an increasing problem in other parts of the world, such as Korea,India.
