Abstract:
The prevalence of hookworm infection was measured by means of stool examinations including direct examination and the Willis technique in 230 children between the ages of 2-14 years living in Brazzaville, People's Republic of the Congo. 120 of them were seen in a hospital. The overall prevalence was 24.3%. The prevalence increased with age until 6-8 years. A highest prevalence was found in male and, whatever the sex, in children in hospital for digestive disorders, anemia-malnutrition and also febrile syndromes-malaria. Coproculture were used to settle the species of hookworm. In 37 positives cases, the proportions of Necator americanus and Ancylostoma duodenale were respectively 91.6% (34/37) and 16.2% (6/37).
