The Conference of the Parties of the Stockholm Convention (COP) allows the use of DDT for public health interventions for disease vector control as recommended by and under the guidance of the World Health Organization (WHO) due to unavailability of locally appropriate and cost-effective alternatives.
Currently, there are organizations and international collaborations working to develop and deploy alternatives to DDT. The DDT Expert group reports to COP in every two years, including the information on Alternatives to DDT. At its eighth meeting, DDT expert group and its report on the assessment of scientific, technical, environmental and economic information on production and use of DDT for disease vector control (UNEP/POPS/COP.8/INF/6) is reported.
DDT web section covers more information in relation to DDT and alternatives to DDT.
