Abstract: Objective: To determine the prevalence of Enterobius vermicularis infection among preschool children in four kindergartens in Ea Sup District, Dak Lak Province, in 2025. Materials and Methods: A cross-sectional study was conducted on 320 systematically selected children from four kindergartens (Hoa Ban, Hoa Phuong, Ea Rok, and Cu Kbang) between April and September 2025. Perianal samples were collected using the Graham method, and E. vermicularis eggs were identified under light microscopy. Results: The overall prevalence of E. vermicularis infection was 13.75%. The highest prevalence was observed at Hoa Ban Kindergarten (17.76%), followed by Cu Kbang (15.69%), Ea Rok (11.11%), and Hoa Phuong (9.26%); however, the differences were not statistically significant (p>0.05). Infection rates were significantly higher among ethnic minority children compared to Kinh children (p<0.05). The prevalence was higher in the 4–5-year-old group, with no significant difference between sexes. E. vermicularis infection was associated with behaviors such as toy biting and finger sucking. Conclusion: The prevalence of E. vermicularis infection among preschool children in Ea Sup District remains a public health concern. Regular deworming programs and hygiene education in kindergartens should be strengthened to reduce transmission.
