If we step away from the faux hysteria generated by JunkScience.com and the Competitive Enterprise Institute, we can get a glimpse of how people seriously concerned about preventing and treating malaria go about doing exactly that.
Here’s a post from a guy named Angus, describing practical steps people traveling to malaria zones should take, and also discussing the one-two punch needed to really squelch malaria: Good medicines for treating people who have malaria, and mosquito control projects (in this case, without DDT).
Note well this paragraph of Angus’s story:
Back in 1982 a WHO-sponsored initiative attempted to eradicate the malaria vector, Anopheles mosquitoes, using the notorious insecticide DDT. Although the incidence of malaria decreased, it also resulted in the death of much poultry and livestock. The campaign was “imposed”, was not integrated, was resented, was not sustained and malaria made a comeback with a vengeance.
Note that DDT obviously was NOT out of use, and therefore we might understand as not banned in Africa, in 1982, contrary to claims from junk science and bogus history purveyors. Note also that the side-effects of the DDT-based program were disastrous enough to make Africans (in Sao Tome e Principe?) wary of future DDT-based programs.

From the U.S. National Institutes of Health: Monthly trends of malaria morbidity and slide positivity rate (SPR) and malaria cases on the island of São Tomé 2003-2009. “Bottom Line: Regular implementation of an island-wide IRS programme was carried out yearly in 2004-2007, and enhanced throughout the island in 2009.Only 50% of asymptomatic carriers were cured with ACT treatment, while 90% of the symptomatic patients were cured by ACT treatment as confirmed with a follow up study.In addition, both daily reports and a regular active surveillance to prevent malaria outbreaks should be established permanently, so that a fast response to epidemics can be effectively made when necessary.”
