The most dangerous vectors of malaria thrive mainly within the village environment. Logically, the adult vectors remain close to their noctur- nal source of human blood, and the developmental stages of these mosquitoes exploit the nearby accumulations of water that form where people have dis- turbed the natural drainage. The borrow pits made in the course of mud-brick construction, tyre tracks, and hoof-prints, for example, promote vector abun- dance in much of sub-Saharan Africa. Malaria then becomes a fixture of vil- lage life, exacting a continuous toll on the health of its host population while generating lethal outbreaks among visitors. As a result, malarious communi- ties tend to be isolated, with their economies frozen at a subsistence level. Productivity is impaired, and the societies that develop in such sites tend to resist change. Affected communities adapt to their isolated state by develop- ing behaviour patterns and social systems that help their members adjust to this reality. The vertically organised anti-malaria programmes that were launched before ] the 1990s could be conducted largely without reference to the behaviour and its control and malaria aspects of social and behavioural The the belief systems of the affected populations. Indoor residual insecticides, the hallmark of the eradication era, were applied uniformly across entire conti- nents. Although residents frequently denied the government spray teams entry to their homes and removed the insecticidal sprays from treated walls, their active participation was largely irrelevant to the intervention. Current anti- malaria programmes, however, generally are organised horizontally and depend heavily on resident participation. The recently launched Roll Back Malaria (RBM) Programme relies mainly on insecticide impregnated bednets (ITNs) and com- bination drug therapy (CT). ITNs must be hung by the people who are to sleep under them and they must be reimpregnated in a timely manner, frequently at the user's expense. Failure to sustain this intervention would result in increased sickness and death due to exposure of relatively non-immune people to new VII SEBbook.qxd 5.9.2003 14:50 Page VIII infections. CT requires a standard schedule of drug administration that relies on the cooperation and understanding of each affected person. Failure to adhere to the prescribed regimen would endanger the long-term efficacy of the regi- • Foreword men. Resident cooperation is even more crucial when environmental manage- ment or housing improvement becomes the intervention modality. These prac- tical reasons drive our current need for a solid understanding of the behav- ioural and social factors that influence malaria risk and that may inhibit or facilitate particular intervention modalities. No longer can interventions be conducted uniformly across broad regions; the problems tend to be local. This monograph commences with a thorough analysis
