Investigation of Head Lice and Intestinal Parasites in Primary and Secondary School in Sivas.

ABSTRACT

Objective: The purpose of this study was to investigate the prevalence of intestinal parasites and head lice in primary school-aged children and to determine a possible relationship between the co-occurrence of ecto-endoparasites. Methods: The study were conducted in three schools in the center of Sivas Sivas Karsiyaka Primary School, Kilavuz IMKB Primary School, and Karsiyaka 27 June Middle School. The presence of head lice and intestinal parasites was investigated in a total of 563 children aged 6 to 17, with 294 girls and 269 boys. Classroom teachers and students were provided with information about intestinal parasites, head lice, and methods of transmission and prevention, and a questionnaire was administered. During the head lice examination, students were inspected with a comb, and samples with nits were examined under a microscope in the laboratory. Cellophane tape and stool samples obtained from the participants were examined on the same day using the native-lugol, flotation, and trichrome staining methods under a light microscope (x10, x40, x100). Results: Five hundred sixty-three children were evaluated for head lice and 15 (2.6%) were found to be positive. During the examination, only nits were found in 11 students (1.9%), and both adult lice and nymphs were seen in 4 students (0.7%). Head lice were found positive in 2 out of 269 boys (0.7%), while 13 out of 294 girls (4.2%) positive (p<0.05). As a result of stool examination in children, Entamoeba coli was found in 11 (1.95%), Giardia intestinalis in 4 (0.71%), Blastocystis sp. in 14 (2.48%), Enterobius vermicularis in 8 (1.42%) and Taenia spp. in 2 (0.35%). Head lice infestation and Taenia spp. were found to coexist in 2 (0.35%) children. Conclusion: In conclusion, although there has been a noticeable decrease in head lice and intestinal parasites among primary school-aged children in Sivas province, these conditions are still present, as evidenced by previous studies conducted in our region.
