Effects of hydraulic installations on the prevalence of Plasmodium falciparum in the Logone plain in Far North region of Cameroun
Abstract
The prevalence of Plasmodium falciparum was determined out on 420 persons in two villages of a hydro-arranged perimeter and two others out of the water intake perimeter in the Far North region in Cameroon. Thick and thin blood smears were stained with Giemsa. Species-specific densities of plasmodia were estimated under a light microscope at high magnification with thin blood smears for identification of parasite species and thick blood smears for densities by counting the number of parasites on the basis of 8,000 white blood cells / microlitre of blood. Results showed that persons of the hydro-arranged perimeter were significantly infected than those out of the hydro-arranged perimeter. In addition persons from 0 to 11 years were significantly more infected than others in the two perimeters. Females were significantly more infected than males in the hydro-arranged perimeter. With or without prevention persons of the hydro-arranged perimeter were significantly more infected than those out of the hydro-arranged perimeter. These results show the importance of the human plasmodia infections and its local variability. These informations were necessary to optimize methods of fight against P. falciparum in the Logone plain and in similar areas.
