Intestinal Parasites Associated with Fingernails of Pupils in Africa

Intestinal parasites, comprising protozoa and helminths, are significant contributors to morbidity and mortality within the human gastrointestinal tract. This study aimed to assess the prevalence of intestinal parasites associated with the fingernails of pupils from two contrasting schools in Calabar, Cross River State, Nigeria. Using thick and thin blood smear techniques alongside formal-ether concentration methods for microscopic examination, 20 samples were analyzed. Results indicated that 11 (55%) of the samples were infected with intestinal parasites. Female pupils showed higher rates of Ascaris (85.71%) and Trichuris (66.67%), while male pupils had a 100% infection rate for Entamoeba. The findings suggest a high prevalence of Ascaris across all age groups, with recommendations for improved hygiene practices among children, such as avoiding barefoot walking, playing in soil, and regular handwashing with soap.
