Worm infections are a health concern in Indonesia and all other tropical nations. A number of species, including roundworms (Ascaris lumbricoides), whipworms (Trichuris trichiura), hookworms (Hookworms), Necator americanus, Ancylostoma duodenale, and Strongyloides stercoralis, are members of the Soil Transmitted Helminth nematodes. Children in elementary school are among the age groups most vulnerable to Ascaris lumbricoides. Without a clean and healthy lifestyle, an Ascaris lumbricoides infection might have major repercussions. Research on the correlation between Ascaris lumbricoides infection and total immunoglobulin E levels in primary school students is therefore required. This study uses a cross-sectional, observational analytical design. Children at Lifuleo Village's elementary schools served as the research subjects. The ECLIA method was used to assess total immunoglobulin E levels, and the Kato-Katz method was used to diagnose Ascaris lumbricoides infection under a microscope. An aberrant total immunoglobulin E level of 12.5% was observed in 42.5% of Ascaris lumbricoides eggs, according to the examination results.

Worms are a health problem that is still common. Worms caused by a group of soil-borne intestinal worms known as Soil Transmitted Helminths (STH). This community service is carried out with the aim of carrying out prevention and counseling about environmental health, especially in helminthiasis in elementary school children in Oehau, Kupang District, East Nusa Tenggara Province. This activity conducts counseling and examination of the community on how to deal with helminthiasis in elementary school children with a subject of 41 children at School Oehau. The results showed that out of 41 samples there were 4 samples that were positively infected with the Soil Transmitted Helminths worm species, the Ascaris lumbricoides egg species with a prevalence of 9.8%. Children's behavior by 73%. Children's knowledge of helminthiasis is 87%. Sanitation of the children's home environment by 88%. Therefore, it is suggested to teachers and parents and especially elementary school children to further improve the Clean and Healthy Lifestyle (PHBS) in order to avoid helminthiasis.
