Healio reports a study on the indoor use of DDT has been submitted to The Lancet, which is one of England’s most prestigious peer-review medical journals. In a press release one of the researchers is quoted as saying:
“Our findings do not support any universal recommendation for indoor residual spraying as an addition to long-lasting insecticidal nets (LLINs) across sub-Saharan Africa,” researcher Steve W. Lindsay, PhD, disease ecologist at Durham University, United Kingdom, said in a press release. “High bed net use is sufficient to protect people against malaria in areas that have low or moderate levels of malaria like The Gambia.”
The scientists seem to have overlooked South Africa which legalized usage of the pesticide. A news report run October of last year in The Sidney Morning Herald points out that malaria death rates in South Africa dropped significantly once the pesticide was utilized.
Amid controversy over the use of the chemical DDT, the report, delivered at a Pan African Malaria conference in Durban, says only 70 people died last year from the mosquito-borne disease compared with 460 deaths recorded in 2000. The number of people who caught malaria has come down to about a tenth of the cases recorded that same year.
As near as I can tell, the Lancet study has been submitted and not peer reviewed.
