title: The control of measles in tropical Africa: a review of past and present efforts.
abstract: Measles in tropical Africa is endemic and cyclical, with a high incidence that usually peaks during the dry seasons. Measles may be a contributing factor in 10% of all deaths among African children. Several problems have hindered measles immunization programs in Africa; these include difficulties in maintaining the cold chain, poor epidemiologic surveillance, and the logistical problems involved in reaching a population that is 80% rural. The United States Agency for International Development and the World Health Organization both have programs that are helping to increase immunization coverage and to solve the problems just mentioned. Many countries have begun to train their own personnel to administer immunization programs. However, because of limited staff and equipment, a high birth rate, and an uncertain social situation, no firm predictions can be made concerning the permanent control of measles in tropical Africa.
