Prevalence of intestinal parasites and risk factors forspecific and multiple helminth infections in a remote city of the Brazilian Amazon.

INTRODUCTION

Few studies have described the risk factors of intestinal parasitic infections in the Amazon.

METHODS

A cross-sectional survey was performed in a City of the State of Amazonas (Brazil) to estimate the prevalence of intestinal parasites and determine the risk factors for helminth infections.

RESULTS

Ascaris lumbricoides was the most prevalent parasite. The main risk factors determined were: not having a latrine for A. lumbricoides infection; being male and having earth or wood floors for hookworm infection; and being male for multiple helminth infections.

CONCLUSIONS

We reported a high prevalence of intestinal parasites and determined some poverty-related risk factors.
