Plasmodium species are transmitted by the bite of an infective female mosquito. Occasionally, transmission occurs by blood transfusion, organ transplantation, needle sharing, nosocomially, or from mother to fetus.

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. The WorldWide Antimalarial Resistance Network WWARN is a collaborative platform generating innovative resources and reliable evidence to inform the malaria community on the factors affecting the efficacy of antimalarial medicines. Searches for new drugs against chloroquine-resistant malaria, especially as they relate to analogues of chloroquine and chemosensitizing agents against the different forms of P. falciparum and P. vivax, should benefit greatly from research work in this area Travelers going to malaria-endemic countries are at risk for contracting the disease, and almost all of the approximately 1,700 cases per year of malaria in the United States are imported. Malaria is a major international public health problem; 91 countries reported an estimated 216 million infections and 445,000 deaths in 2016, according to the World Health Organization (WHO) World Malaria Report 2017.

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. Drug Resistance in the Malaria-Endemic World.

Center for Global Health Division of Parasitic Diseases and Malaria. Who can take chloroquine? Chloroquine can be prescribed to adults and children of all ages. It can also be safely taken by pregnant. women and nursing mothers. Who should not take chloroquine? People with psoriasis should not take. The clinical usefulness of chloroquine, and in some recent cases of quinine as well, has been much reduced by the evolution and spread of chloroquine resistant malaria parasites. The mechanism of resistance involves a reduced accumulation of the drug, although again the mechanism involved is controversial. Resistance to chloroquine of malaria strains is known to be associated with a parasite protein named PfCRT, the mutated form of which is able to reduce chloroquine accumulation in the digestive vacuole of the pathogen. Whether the protein mediates extrusion of the drug acting as a channel or as a carrier and which is the protonation state of its chloroquine substrate is the subject of a.
