Abstract
Between April 1974 and March 1976 surveillance of measles has been conducted by 12 fieldworkers making fortnightly home visits among a total population of 24,000 living in nearly 4000 households scattered in variable density throughout an area of 87 sq km in the northern division of the Machakos district, Kenya. The diagnosis of measles was verified by one of the project's physicians according to standardized procedures and was, whenever possible, supported by virus isolation and serum antibody level determination. Because not all reported patients were actually seen during the period of clinical manifestations, the diagnosis remained doubtful in a number of cases. Incidence and mortality figures have been estimated with 95% confidence limits based on the assumption that doubtful cases represent a probability of measles of .33 and probable cases a probability of .67.
