    Chloroquine has been the mainstay of treatment for Plasmodium vivax for over 60 years. 1, 2 The first observations of chloroquine-resistant P vivax were published in 1989, 3,4 and over the. Chloroquine resistance is widespread in P. falciparum and is reported in P. vivax. Before using Chloroquine for prophylaxis, it should be ascertained whether Chloroquine is appropriate for use in the region to be visited by the traveler. Information regarding the geographic areas where resistance to Chloroquine occurs, is available at the. Background. Chloroquine is the first-line treatment for Plasmodium vivax malaria in most endemic countries, but resistance is increasing. Monitoring of antimalarial efficacy is essential, but in P vivax infections the assessment of treatment efficacy is confounded by relapse from the dormant liver stages.

    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].
