Over the years, Oxfam has been involved in a wide variety of health-related projects. The Practical Health Guides draw on this experience to put forward ideas on best practice in the provision of health care and services in developing countries The number of refugees and displaced persons has increased greatly in recent years. At least 80 per cent of them are living in tropical or semi-tropical countries where vector-borne diseases, such as malaria, dengue fever and sleeping sickness are common and cause widespread sickness and death in the crowded conditions of refugee camps. This work is intended to help development workers and planners to identify and assess the risks of vector-borne diseases in a camp and to plan and implement cost-effective ways of controlling them. The main vector-borne diseases are described, the importance of identifying the particular disease and its vector and of considering a variety of methods of control is emphasized. The book discusses the need for a community-based approach to vector control, the safe use of insecticides and selection of spraying equipment. Also included are lists of suppliers of insecticides and equipment, sources of advice and recommended texts.
