Introduction: Currently, Paraguay has no data on the prevalence of soil-transmitted geohelminth infection in schoolchildren aged 6 to 12 years.

Aim: To determine the prevalence and intensity of infection by Ascaris lumbricoides, Trichuris trichiura and hookworms and the socio-cultural-environmental characteristics of the affected population.

Methods: Descriptive, cross-sectional study, in three semi-tropical climatic zones: continental, semi steppe and humid. A total of 1,404 schoolchildren from 20 schools in eight departments were selected from the country's three climate zones. Copro-parasitological exams were analyzed in situ with the Kato-Katz method.

Results: The national prevalence for geohelminthiasis was 3.73% (95% CI = 2.8-4.8). The risk factors found were consumption of well water OR: 2.88 (95% CI = 1.64-2.07), ground floor in housing OR: 2.56 (95% CI = 1.45-4.50) and lack of flushing water baths in households OR: 2.29 (95% CI = 1.23-4.28).

Conclusion: Although the national prevalence of geohelminthiasis was low, it is recommended to promote good hygienic practices, use of footwear, and safe water consumption, as well as designing interventions with all relevant sectors to improve access to safe water and improved basic sanitation facilities.
