Intestinal parasitic infections caused by non-Soil Transmitted Helminths (non-STH), particularly Enterobius vermicularis, remain a public health problem in developing countries, including Indonesia. Transmission does not require soil as a medium but occurs through direct contact, autoinfection, or unclean household environments. In children, infection may cause perianal itching, sleep disturbances, loss of appetite, and secondary infections due to scratching, which can affect nutritional status, sleep quality, and overall growth and development. This study was conducted in Kupang City, an endemic area of helminthiasis, to determine the prevalence and risk factors of E. vermicularis infection among children aged 1–5 years. A cross-sectional design with total sampling was applied to 30 children living in RT 008/RW 003, Penfui Timur Village, Kupang Tengah District, from February to May 2025. Risk factor data were collected using structured questionnaires covering personal hygiene, environmental sanitation, socioeconomic status, and parental education. Infection was identified using the scotch tape technique and microscopic examination. The results showed a prevalence of 7% (2 out of 30 children), mainly among boys aged ≥4 years, with poor personal hygiene, inadequate sanitation, low economic status, and parental education at elementary school level or below. In conclusion, enterobiasis in children is influenced by a combination of behavioral, environmental, and socioeconomic factors. Prevention should not rely solely on mass deworming programs but also require continuous health education for parents, improved hygiene practices, and household sanitation.

Worm infestation due to Soil-Transmitted Helminths (STH) infection remains a public health problem, especially among elementary school children who frequently interact with contaminated soil. This condition is a major concern because it can cause long-term health problems, particularly in terms of physical growth and development of children. This study aims to identify the presence of STH worm eggs and larvae in soil and fecal samples of children in Bekoso Village, Pasir Belengkong District, Paser Regency, East Kalimantan. This study used a descriptive approach with a cross-sectional design. The samples used consisted of 23 soil points taken from oil palm plantations with sandy and loose soil criteria, as well as 16 fecal samples from elementary school children. Fecal examination was carried out using the Kato-Katz method to detect worm eggs, while the soil was examined using the Baermann technique to detect worm larvae. The results showed that 25% of children's fecal samples were infected with worm eggs, with 12.5% containing hookworm eggs, 12.5% Taenia sp. eggs, and 6.25% Ascaris lumbricoides eggs. In soil samples, 60.87% tested positive for Strongyloides stercoralis larvae and 26.09% tested positive for Ascaris lumbricoides eggs. These findings indicate a high risk of STH infection in children in the area. Environmental factors such as soil moisture, soil texture suitable for worm breeding, and poor personal hygiene practices are suspected to be the main causes of the spread of infection. This study emphasizes the importance of education on clean and healthy living behaviors (PHBS) and improving environmental sanitation to reduce cases of worm infection, especially in endemic areas such as Bekoso Village. More comprehensive prevention efforts are urgently needed to address this problem and improve public health, especially among elementary school children.

Worm disease is included in the neglected diseases group, which is a chronic infection that often does not show clear symptoms and the impact is only felt in the long term. Worms included in the Soil Transmitted Helminths (STH) group can spread through the soil and include Ascaris lumbricoides, Trichuris trichiura, hookworms (Necator americanus and Ancylostoma duodenale), and Strongyloides stercoralis. This worm infection can cause malnutrition, impaired child growth, decreased cognitive abilities, iron deficiency anemia, and reduced learning performance. One indicator of worm infection is an increase in eosinophil levels, which are part of the body's immune system. This study aims to analyze the relationship between Ascaris lumbricoides infection and the number of eosinophils in stunted children in Noelbaki Village, Kupang Regency, East Nusa Tenggara. This study used an analytical observational design with a case-control study approach, involving stunted children as subjects. The results showed the prevalence of Ascaris lumbricoides eggs of 51.3%, and an increase in abnormal eosinophils of 87.5% in cases of infection. Statistical tests revealed a significant relationship between A. lumbricoides infection and eosinophil count (p = 0.000). However, this study did not consider the possibility of allergy as a factor in increasing eosinophils.
