For two years the United Nations paid lip service to the truth that the insecticide DDT is a vital component of malaria control, but last week UN abandoned science in favor of superstition. The result is UN promotion of more dangerous and less efficient malaria control techniques.
On May 5th, the World Health Organization (WHO) and the United Nations Environment Program announced plans to reduce DDT use by 30% by 2014 and completely eliminate it by around 2020. In the mean time, the UN will roll out initiatives in 40 countries to test non-chemical methods of malaria control. In particular UN wants to scale up the programs of Central America, which have relied on “pharmacosuppression”. Essentially, uninfected people in high risk locations are given the antimalarial drug chloroquine to suppress any future infection. In 2004, 3,400 malaria cases were diagnosed in Mexico, 6,897 in Nicaragua, and almost half a million in Brazil. But both Mexico and Nicaragua each distributed more anti-malaria pills (mostly chloroquine pills) than Brazil. Chloroquine is a wonderful drug at combating malaria and has saved millions of lives when used therapeutically, as in Brazil,, but prophylactic use is not safe because it is quite toxic and has led to heart problems when used repeatedly.
