Research by German scientists to discover a substitute for quinine led to the synthesis in 1934 of Resochin (chloroquine) and Sontochin (3-methyl-chloroquine). These compounds belonged to a new class of antimalarials, the four-amino quinolines.
Following the war, chloroquine and DDT emerged as the two principal weapons in WHOs global eradication malaria campaign. Subsequently, chloroquine resistant P. falciparum probably arose in four separate locations starting with the Thai-Cambodian border around 1957; in Venezuela and parts of Colombia around 1960; in Papua New Guinea in the mid-1970s and in Africa starting in 1978 in Kenya and Tanzania and spreading by 1983 to Sudan, Uganda, Zambia and Malawi.
