title: [Evaluation of the health status of nomadic and semi-nomadic populations of the Gourma-Mali: epidemiologic approach. I. Introduction, material and methods].
abstract: The authors set out the methodology and the practical way used in transverse epidemiological investigation with a descriptive aim which was made in natural area: Gourma-Mali. This part of the Sahel, hard to reach, is placed deep in the bend of the Niger river. The population is estimated at 100.000. The weather, ecological and human conditions have been unsettled by the drought. Sometimes, it was difficult to collect the data among the nomadic and seminomadic populations (Tamachèques, Peuls, Maures, Bellahs, Sonraïs). This investigation shows well the practical problems that this kind of study sets out in difficult bioclimatological and ethnological conditions.
