It is the deadliest parasitic disease killing over one million people each year. 90 % of the deaths occur south of the Sahara desert and most are under five-year-old children. Low dose of plaquenil Toxic dose of chloroquine Haemoglobin degradation during the erythrocytic life stages is the major function of the food vacuole FV of Plasmodium falciparum and the target of several anti-malarial drugs that interfere with this metabolic pathway, killing the parasite. Two multi-spanning food vacuole membrane proteins are known, the multidrug resistance protein 1 PfMDR1 and Chloroquine Resistance Transporter PfCRT. In most parts of the world, P. falciparum is resistant to chloroquine, and the recommended treatment is artemisinin bases combinations. Primaquine should be used in P. vivax and P. ovale malaria for eradicating the persisting liver forms and in P. falciparum malaria to destroy the gametocytes, so as to prevent the spread of infection. Higher mean parasitaemia in untreated oligosymptomatic carriers of overtly chloroquine-resistant P. falciparum than in carriers of more sensitive parasites was another indication of higher viability and biological advantage of chloroquine-resistant P. falciparum that may conceivably have clinical implications. Even within tropical and subtropical areas, malaria does not usually occur at high altitudes (over 1500 meters), during colder seasons, in countries of successful malaria programs or in deserts. In addition to Africa, malaria occurs in South and Southeast Asia, Central and South America, the Caribbean and the Middle East.

Update Chloroquine-Resistant Plasmodium falciparum -- Africa. Chloroquine resistance of Plasmodium falciparum a.. Genetic diversity and chloroquine selective sweeps in.. Unfortunately, within a decade of its introduction, P. falciparum parasite resistance to chloroquine was observed in most of the malaria-endemic countries. Nowadays, insurgence of resistance against chloroquine is a considerable hurdle for malaria control. 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. Chloroquine is reported to be effective in Ethiopia,7-9 despite an earlier report of the presence of chloroquine-tolerant strains of P falciparum in patients given a single dose of 10 mg base/Chloroquine-resistant falciparum malaria has now emerged in localised parts of Ethiopia in areas bordering Somalia, Kenya, and Sudan, as documented by passive case detection at the MVDCP headquarters in Addis Ababa.
