The scientists from the United States and South Africa said the insecticide, banned decades ago in most of the world, should only be used as a last resort in combating malaria. The stance of the panel, led by a University of California epidemiologist, is likely to be controversial with public health officials. In many African countries, as well as India and North Korea, the pesticide is sprayed inside homes and buildings to kill mosquitoes that carry malaria.
The organization has offices in South Africa and the United States and conducts critical analysis of malaria control programs and funding agencies and strive to build more transparent, accountable, and effective malaria control programs. Africa Fighting Malaria has worked to defend the decisions of malaria control programs to use DDT and to argue for a sound, scientific assessment of the chemical.
The organization has a policy of not accepting funds from the insecticides industry and has never received any donations from this sector. Copyright notice Publication of EHP lies in the public domain and is therefore without copyright.

Given the enormous and proven public health benefits arising from the use of DDT in disease control, it is incumbent on van den Berg to cite human health harm from DDT exposure that fulfills the basic epidemiologic criteria for a clear and unambiguous cause-and-effect relationship.
Many prestigious and authoritative groups and individuals with no ideologic agenda have evaluated potential DDT harms over the last 70 years, and have consistently found no evidence of DDT harm that would cancel out the enormous health benefits of its use in malaria-endemic countries.
In addition, van den Berg neglected to report on the evidence of growing populations wherever DDT has been used in malaria control, a fact that would undermine the idea that DDT significantly harms human fertility.
Accumulations of data and results of distinct studies that provide weak or no evidence of harm to human health do not argue for a hidden cause—effect relationship; they argue instead that no cause—effect relationship exists.
Where DDT has been used in malaria control over many decades, populations have grown and health outcomes have improved. Documentation from many studies shows that DDT movement is likely to be so small and so gradual as to be insignificant Smith and Webley ; Viera et al.
DDT use in malaria control is by definition used indoors, whereas environmental management, which is promoted as an alternative to the use of insecticides for malaria control, is by definition performed outdoors e.
If van den Berg has evidence to show that small uses of DDT sprayed indoors is more harmful than massive environmental changes outdoors, he should have included it in his review.
It is a demonstrable fact that spraying insecticides to kill insects will select for resistance. Repellent action does not lead to toxic resistance because repellency reduces mortality, and it is mortality that exerts selective pressure for resistance.
Alternatives to DDT are always welcome. He relied on case studies Barat of four countries to argue that decentralization can benefit malaria control.
However, elsewhere, these case studies have been criticized and shown to be based on unreliable and even false data Attaran et al. IRS and other malaria control operations require, to a significant degree, centralized decision making, planning, and budgeting.
The trend of decentralization since the s has not only limited the scope of IRS but has also been a factor contributing to the gradual increase in malaria transmission around the world.
In addition, as documented by the World Health Organizationdecentralization was vigorously opposed by many malaria scientists. After almost 70 years of use, DDT—when used in IRS programs—remains one of the safest and most effective methods of saving lives from malaria.

DDT environmental persistence from its use in a vector control program:A panel of scientists recommended today that the spraying of DDT in malaria-plagued Africa and Asia should be greatly reduced because people are exposed in their homes to high levels that may.
Malaria, Mosquitoes, and DDT. The toxic war against a global disease This year, like every other year within the past couple of decades, uncountable trillions of mosquitoes will inject malaria parasites into human blood streams billions of times.
Malaria (also called biduoterian fever, blackwater fever, falciparum malaria, plasmodium, Quartan malaria, and tertian malaria) is one of the most infectious and most common diseases in the world.
This serious, sometimes-fatal disease is caused by a parasite that is carried by a certain species of mosquito called the Anopheles. Africa Fighting Malaria, Washington, DC, E-mail: [email protected] In his commentary “Global Status of DDT and Its Alternatives for Use in Vector Control to.
