title: [Epidemiological aspects of dracunculosis in Benin. 1. Incidence, eruption location and incidence of reinfestation].
abstract: A prospective survey was conducted in five villages in the central part of Benin. Population of these dracunculiasis infected villages was range from 150 to 300 people. A weekly visit led to note dates of worm eruption and to follow up evolution of the disease. 723 patients were observed between 1985 and 1989. Infants were rarely affected. The highest incidence occurred in men from 18 to 45 years old. In other age groups, incidence was not significantly different from group to others. 90% of emergencies were located in lower limbs. Recurrent infections from year to year were observed with a significant higher frequency in 20% of people. These people were not distinctive from others. Such a result could be explained by a special behaviour concerning water supply, conservation or treatment. Average duration of the disease was 106 days. Duration of the disease was not linked to educational or medical equipment nor isolation of village.
