[Malaria in Gabon. 2. Evaluation of the qualitative and quantitative prevalence of parasites in the total school and preschool population of the country].
The distribution of carriers of hematozoa in the pre-school and school age group in Gabon has been established with the help of systematic enquiry. The plasmodial indexes vary between 11 and 32% in the savanna zones of the south-east, they rise to 64.9% in the forest regions of the north of the country, and in the urban zones (Libreville, Franceville, Lambarene) 6 to 18% of the school children are gametocyte carriers. In Libreville, amongst the febrile children seen in pediatric consultation, the prevalence reached 30%. Boys and girls are equally affected. The most important prevalence is observed in the group of children from 5 to 10 years of age. P. falciparum is found in 96.4% of the cases, P. malariae in 5.3% and P. ovale in 2.4%. The study of the parasitic load revealed that 56% of the positive subjects had less than 10,000 asexual forms/mm3, 44% more than 10,000 hematozoa/mm3. These results are similar to those of the neighbouring countries of equatorial Africa.
