A community approach to trachoma control in the Northern Transvaal.

Trachoma represents the largest single cause of preventable blindness in the Black population of the Northern Transvaal. Epidemiological and cultural considerations indicate the necessity of community involvement in trachoma control at the household level. Involvement of the community by means of groups of voluntary health workers (care groups) has proved to be effective and acceptable to the local inhabitants. These groups, who form part of the comprehensive health system, integrate trachoma control into the primary health care activities of the area.
