Abstract
A total of 113,254 individuals from 100 venezuelan municipalities were studied by mean of Kato-Katz coprological examination and the geohelminth prevalences were established. The national prevalences of T. trichiura, A. lumbricoides and Anquilostomideos were 32.6%, 26.9% and 5.6% respectively+. For T. trichiura the highest values were obtained for the following municipalities: Arévalo González (54.6%) in Miranda state, Urama (76.9%) in Carabobo state and Punta de Piedra (78.4%) in Sucre state. For A. lumbricoides the highest values were determined in Punta de Piedra (63%), Tunapuy (61.9%) in Sucre state and Arévalo González (62.7%) in Miranda state. For hookworm the highest values were detected in El Amparo (39.5%) and San Camilo (35.9%) in the state of Apure. In relation to the age, the highest prevalence of Ascariosis and Trichuriosis were determined in pre-school and school children and for hookworm in adolescents and adults. A high variability between the municipalities belonging to the same state for the three geohelminths was observed.
