Vector-control synergies, between 'roll back malaria' and the Global Programme to Eliminate Lymphatic Filariasis, in South-east Asia.

The problems of, and opportunities for the control of filarial vectors in the World Health Organization's South-east Asian Region are summarized and discussed. Together, the countries in this region have more than half of the world's burden of lymphatic filariasis (LF), most of it caused by Wuchereria bancrofti transmitted by Culex quinquefasciatus. Although the vectors and the epidemiology and distribution of LF in this area largely differ from those of malaria, some vector-control methods (such as bednets and other personal-protection measures, breeding-site reduction and environmental management) can have an impact on LF, malaria and other mosquito-borne diseases. Some of the relevant issues of programme management and integrated vector control are reviewed.
