Malaria in Sri Lanka - Current Knowledge on Transmission and Control (IDA/World Bank Health Services: Water Management for Malaria Control in an area of the Huruluwewa Watershed

Duration : January 1, 2000 - January 1, 2004

Despite large-scale control efforts, malaria continues to be a major public health problem in Sri Lanka, which not only causes hardship to the patients and their families but also consumes a large share of the government's budget for health care. Over the years, a large pool of knowledge has accumulated on malaria in Sri Lanka. The present review includes a broad range of published literature of relevance for a description of malaria in Sri Lanka, including the control aspect of the disease. Based on the literature examined, a general overview of the status of research in Sri Lanka is given and areas where knowledge is lacking and further studies are required are identified. Objectives: a. Implement a regime of water releases along the Yan Oya stream that will be effective in controlling the vector of malaria in the area (determined by entomological monitoring), and thereby reduce disease incidence (monitored by a malaria clinic in the study area, and health statistics from the surrounding government health care centers). b. Develop institutional arrangements with the stakeholders (Mahaweli Authority of Sri Lanka, farmers) that would serve as the basis for a policy framework for the wider implementation of such an approach to malaria control. Expected outcomes: The study will establish whether scientific management of water in the Yan-Oya stream will be effective in: a. reducing the breeding of the major vector of malaria b. maintaining low densities of adult vectors in the area c. maintain low levels of malaria in the study villages. Sustainability: The sustainability of the approach will be evaluated in terms of the level of community participation. It will also establish the cost effectiveness of this intervention both in terms of the health benefit and irrigation efficiency. If successful and cost effective, this approach will later serve as a model for the implementation of water management for vector control on a wider scale in other tank cascade systems in the dry zone of Sri Lanka.
