History of malaria millennium BCE in Greece and China. For thousands of years, traditional herbal remedies have been used to treat malaria. The first effective treatment for malaria came from the bark of cinchona tree, which contains quinine. After the link to mosquitos and their parasites were identified in the early twentieth century, mosquito control measures such as widespread use of the insecticide DDT, swamp drainage, covering or oiling the surface of open water sources, indoor residual spraying and use of insecticide treated nets was initiated. Prophylactic quinine was prescribed in malaria endemic areas, and new therapeutic drugs, including chloroquine and artemisinins, were
Human genetic resistance to malaria only gene conferring innate resistance to falciparum malaria; there could be many such genes exerting more modest effects that are challenging to detect by GWA because of the low levels of linkage disequilibrium in African populations. However the same GWA association in two populations is powerful evidence that the single gene conferring strongest innate resistance to "falciparum" malaria is that encoding HbS. The fitnesses of different genotypes in an African region where there is intense malarial selection were estimated by Anthony Allison in 1954. In the Baamba population living in the Semliki Forest region in Western Uganda the sickle-cell heterozygote
