[Prevalence and intensity of geohelminths infection characterizing the socio-cultural and environmental factors that affect the infection of school children, Paraguay, 2015].

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.
