A cross-sectional study was performed among 213 participants from rural community of Muarakaman district and Marangkayu districts, East Kalimantan province, Indonesia. 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 and odd ratio analysis were used for study correlation and level of geographical risk factors and S. stercoralis infection. We found S stercoralis infection in East Kalimantan Province was 17 (8%). Geographical risk factors While pH of soil, clay content of soil, vegetation, and villages area have not correlated significant with S. stercoralis infection (p value > 0.05). Elevation from above sea (≥41.6m) was highest odd of S. stercoralis infection OR: 2.72 (95%CI: (1.30-5.66). Geographical factors might support survival ability of S. stercoralis larvae for migrating and transmission. Essential geographical risk factors of the infections should be used for preventing program of reduction prevalence S. stercoralis infection.
