    History of chloroquine resistance


    Rapid diagnostic assays for Pf CRT mutations are already employed as surveillance tools for drug resistance. Here, we review recent field studies that support the central role of Pf CRT mutations in chloroquine resistance.

Chloroquine is active against the erythrocytic forms Fig. 6.3 of sensitive strains of all species of malaria, and it is also gametocidal against P. vivax, P. malariae, and P. ovale. 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.

    Recognition of the value of chloroquine was delayed, and it was not brought forward until it was reevaluated in the United States and designated the drug of choice against malaria near the end of World War II [3]. These studies suggest chloroquine resistance arose in ⩾4 distinct geographic foci and substantiate an important role of immunity in the outcomes of resistant infections after chloroquine treatment. Investigation of the resistance mechanisms and of the role of immunity in therapeutic outcomes will support new approaches to drugs that can take the place of chloroquine or augment its efficiency Early in the 20th century, intense demands for an effective quinine substitute launched the discovery and evaluation of a series of organic compounds (beginning with methylene blue), which led to pamaquine and quinacrine after World War I and ultimately produced chloroquine in 1934 [1, 2].

    Chloroquine, synthetic drug used in the treatment of malaria. Chloroquine, introduced into medicine in the 1940s, is a member of an important series of chemically related antimalarial agents, the quinoline derivatives. Chloroquine is administered orally as chloroquine phosphate. It also can be When deciding which drug to use, consider specific itinerary, length of trip, cost of drug, previous adverse reactions to antimalarials, drug allergies, and current medical history. All travelers should seek medical attention in the event of fever during or after return from travel to areas with malaria. A closer look at the genesis of chloroquine resistance along the Thailand–Cambodia border, which became ground zero for the emergence of chloroquine resistance in the 1950s and 1960s, reveals a.
