Ecological Risk Factors of Strongyloides stercoralis Infection Sourrounding Desforestration Areas East Kalimantan, Indonesia

Abstract

Aims: The study to assess the prevalence of Strongyloides stercoralis/ S. stercoralis infection, and to correlate environmental risk factors with the prevalence of S. stercoralis infection. Study Design:  We perform a cross-sectional study in rural community in Muarakaman and Marangkayu district to analysis of geography, texture of soil, humidity, hookworm and strongyloides in pet, vegetation, elevation, volume rain, the number of days of rain yearly, temperature and quality of soil as clay content, organic carbon of soil and pH of soil then was correlated with prevalence of strongyloidiasis.. Place and Duration of Study: The study was carried out in rural area of Muarakaman District and Marangkayu District East Kalimantan Province, Indonesia. This research is a community based, had conducted during 2021-2022. Methodology: This study would show the infection rates, correlation analysis between environmental risk factors and prevalence of hookworm infection with statistical analysis. We performed a cross-sectional study among 213 participants from rural community. In this study used two diagnostic methods: Kato Katz and Koga agar plate culture/KAP culture for diagnosing of S. stercoralis infection. Pearson chi-square analysis was used for study correlation between ecological risk factors S. stercoralis infection. Results: S. stercoralis infection was found in this study; 34 (8.0%), Ecological risk factors have significant correlation and high odd ratio of prevalence of S. stercoralis infection. Ecological risk factors have significant correlation and high odd ratio of prevalence of S. stercoralis infection such as district, humidity, temperature, volume and amount day of rain organic carbon of soil, elevation of location from above a sea Conclusion: The Ecological risk factors of the infections could be used in preventing program to reduce the prevalence of hookworm and S. stercoralis infection.
