    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.

    P. falciparum schizonts tend to fill up to about two-thirds of the host red blood cell, and contain 8-24 merozoites see image below for development of schizont. However, schizonts of P. falciparum are rarely seen in peripheral blood; instead, multiple, smaller rings are the usual diagnostic sign. 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.

    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.

  6. Chloroquine CQ has been the mainstay of treatment of malaria for decades. This cost-effective and safe drug has become ineffective for treatment of falciparum malaria in many parts of the world due to development of resistance by the parasite. In addition CQ is not gametocytocidal for P. falciparum and thus cannot block transmission. The extent of problem of chloroquine resistance in P.

    Plasmodium falciparum chloroquine resistance is a major cause of worldwide increases in malaria mortality and morbidity. Recent laboratory and clinical studies have associated chloroquine resistance with point mutations in the gene pfcrt. However, direct proof of a causal relationship has remained elusive and most models have posited a multigenic basis of resistance. The first confirmed cases of chloroquine-resistant Plasmodium falciparum acquired in Africa were reported in 1978 1 and occurred in non-immune travelers who had been in East Africa for relatively short periods of time. P. vivax and P. ovale. Chloroquine or hydroxychloroquine remains an effective choice for all P. vivax and P. ovale infections except for P. vivax infections acquired in Papua New Guinea or Indonesia. The regimens listed for the treatment of P. falciparum are also effective and may be used.

    Genetic architecture of artemisinin-resistant Plasmodium falciparum. Analysis of the fine structure of the parasite population showed that the fd, arps10, mdr2 and crt polymorphisms are markers of a genetic background on which kelch13 mutations are particularly likely to arise and that they correlate with the contemporary geographical boundaries and population frequencies of artemisinin resistance.
