Early diagnosis and treatment of malaria cases is one of the basic elements of the current global malaria control strategy. In order to provide this service to people in rural areas there is a need for new cost-effective approaches. To ensure that such new approaches are acceptable to the target communities, it is important to know the rationale for people's malaria treatment-seeking behavior. The present study provides insights into the reasons for people's preferences for different types of healthcare facilities and describes variation of these preferences within a rural community in Sri Lanka. The study reports on the experiences with the establishment of a village health facility and its effect on the treatment-seeking behavior of the population. After the introduction of the village treatment center it quickly took over the role of main provider for diagnosis and treatment of malaria from the government facilities. The treatment center did not improve the response time in seeking treatment for young children, but the delay for adults was reduced by 1-2 days. Mothers with small children often preferred the government facilities since they wanted a more qualified opinion than available from the locally recruited staff of the village treatment center. The treatment center significantly reduced the stress and discomfort experienced by the elderly and handicapped segment of the community. The study indicated that the effective catchment area of a village treatment center will be influenced by the degree of initial support from key individuals in the communities, the selection procedure and training of assistants, and the history of the relationships between different villages to be served by the center. The government health services and communities across the dry zone of Sri Lanka could benefit substantially from the establishment of more village treatment centers. To ensure the long-term sustainability of these type of facilities it is necessary to assess the feasibility of charging a user fee and establishing multi-purpose clinics. Government policies and administrative procedures will need to be adjusted to make the successful operation of village treatment centers possible.

Background: In Sri Lanka, the major malaria vector Anopheles culicifacies breeds in pools formed in streams and river beds and it is likely that people living close to such breeding sites are at higher risk of malaria than people living further away. This study was done to quantify the importance of house location relative to vector breeding sites for the occurrence of malaria in order to assess the usefulness of this parameter in future malaria risk maps. Such risk maps could be important tools for planning efficient malaria control measures. Methods -- In a group of seven villages in north central Sri Lanka, malaria cases were compared with community controls for distance from house to breeding sites and a number of other variables, including type of housing construction and use of anti-mosquito measures. The presence of An. culicifacies in bedrooms was determined by indoor insecticide spray collections.Results -- People living within 750 m of the local stream, which was the established vector-breeding site, were at much higher risk for malaria than people living further away (odds ratio adjusted for confounding by other variables 5.93, 95% CI: 3.50–8.91). Houses close to the stream also had more adult An. culicifacies in the bedrooms. Poor housing construction was an independent risk factor for malaria.Conclusions -- Risk maps of malaria in Sri Lanka can be based on the location of houses relative to streams and rivers that are potential breeding sites for the malaria vector An. culicifacies. A distance of 750 m is suggested as the cut-off point in defining low- and high-risk villages.

In Sri Lanka, malaria is a major public health problem. In some of the remote areas, access to health care and protective measures is hard and larviciding is applied as a supplementary strategy. In the dry zone in North-Central Sri Lanka the main malaria vector responsible for epidemics is Anopheles culicifacies. It breeds in riverbed pools of natural streams such as Yan Oya, which is used as a conveyance canal for downstream irrigation, but not maintained as such. A critical stretch of Yan Oya was selected because of its vector breeding potential and clear association with malaria cases. Mosquito larval populations were monitored bi-weekly from 2000 till 2003; water levels twice a day. Hospital records were complemented with blood slides. In collaboration with the irrigation agency, environmental measures were developed and streambed profiles measured before and after intervention. In the dry season of late 2001 the streambed was cleared of fallen trees, rocks and other barricades, and leveled using heavy machinery and manual labor. Upstream reservoirs and hydraulic structures were repaired for better regulation of the water flow. Costs were shared between the irrigation agency and the project. Larvae of An. culicifacies and An. varuna were found at the stream margins before and after intervention at low flows. After intervention, larval abundance of An. varuna, a secondary malaria vector, increased at two of the sampling points, probably as a result of human activities upstream, such as the construction of temporary dams for irrigation. Natural precipitation and supplementary water releases from the upstream reservoirs increased the water level and reduced breeding levels down to a negligible level within two months. Abundance of An. culicifacies was recorded at very low levels throughout the post-intervention period. Low malaria incidence was reported for the year 2000, and no cases for 2001 and 2002, which might reflect the success of the intervention. However, overall malaria prevalence in the country was also low. Therefore a systematic long-term monitoring program is underway to assess the true impact of the control measures. More than three years after the intervention, the rehabilitated stretch is still visibly different from the untouched part. Additional benefits of the intervention included increased efficiencies of water delivery and reduction of floods in the wet season. Costs of environmental management like this are high for any health intervention, but benefits may stretch over several years and go beyond malaria control. Similar interventions appear feasible at streams elsewhere in South Asia.
