[Evaluation of the main intestinal parasitosis in 860 Ivory Coast children from thirteen different villages (author's transl)].

A survey has been carried out in 2 forest villages, 9 savanna villages and 2 Abidjan suburb districts. A total sample of 860 children aged between 6 and 15, has been examined. Data tabulation indicated a prevalence of the main intestinal nematodes, of S. mansoni and of E. histolytica, with variable respective percentage. Ascaris lumbricoides affected 26 p. 100 of children but is less frequent in the savanna areas than in the forest areas. Trichiuris trichiura affected 1 child out of 4 but infestation rate reached 76 p. 100 in the Abidjan suburb district. Necator americanus is the most frequently detected parasite (67 p. 100) and is more frequent in the forest areas than in the 2 savanna villages. E. histolytica has an uniform and low (5 p. 100) geographical distribution. S. mansoni has such an irregular distribution that no extrapolation is possible from the results obtained to the geographical area considered. Its infestation rates is from 1 p. 100 to 60 p. 100 with important differences inside small geographical zones.
