    Abstract:
    BACKGROUND: Orphans may be envisaged to have sub-optimal care and may be predisposed to high worm burden. This study was undertaken to determine prevalence and intensity of intestinal helminthiasis in children living in orphanages in Benin City, Nigeria. METHODS: Fresh stool samples from 150 children (0-17 years) living in 10 orphanages in Benin City, were analyzed using the Kato-Katz technique for the detection of ova of helminths between January and April, 2011. RESULTS: The subjects consisted of 62 (41.3%) males and 88 (58.7%)females; mean age (+/- standard deviation SD) 7.0 +/- 4.6 years, and mean (+/- SD) years lived in the orphanage was 4.0 +/- 3.7 years. Prevalence of intestinal helminthiasis was 20.7% and this prevalence was highest in children ages 12-17years, children who had lived longer years in the orphanages and in orphanages with poor child/care-giver ratio (orphanage F = 12.0: 1 and orphanage H = 7.3: 1). Mean (+/- SD) age (8.7 +/- 4.5 years) of infected subjects was significantly higher than (6.6 +/- 4.5 years) observed in non-infected subjects (p = 0.023). Ascaris lumbricoides and Trichuris trichiura were the intestinal helminths isolated. Intensity of intestinal helminths was light in 24/31 (77.4%) and moderate in 7/31 (22.6%) infected subjects. Median egg per gram was 999 eggs per gram and range was 48-8000. CONCLUSION: Improved child/care-giver ratio in orphanages will reduce worm burden in orphanages in Benin City.
