Abstract Objective This study aimed to determine the prevalence and establish some risk factors associated with the acquisition of gastrointestinal parasitic infections in school children in Accra, Ghana. Results The overall prevalence of intestinal parasitic infection was 15%. Giardia lamblia (10%) and Schistosoma mansoni (1.7%) were the common parasites found. Out of the 15% students postive for intestinal parasites, 13.6% had single parasites and 1.3% had double parasitic infections. Children between the ages of 4–5 and 6–7 years (20% each) had the most parasitic infections. The prevalence of intestinal parasitic infection was not significantly related to gender (p = 0.1451), and source of drinking water (p = 0.8832). However, a statistically significant association between children infected with parasites and close proximity to domestic animals or pets was observed (p = 0.0284). Continuous education on personal hygiene, environmental sanitation and deworming of domestic animals or pets are required to reduce the prevalence of intestinal parasites in school children in Accra.

Intestinal parasitic infections (IPIs) in school children are a public health problem in most developing countries.A cross sectional survey was conducted from May to July 2016 with school children living in overcrowded urban slums in Accra, Ghana. A simple random sample of 300 children aged 2-9 years was collected. The study used structured pre-tested questionnaire and stool tests to obtain information on epidemiological, sanitation habits, employment and education status of parents and children. Data were analysed using appropriate descriptive, univariate and multivariable logistic tools of analyses. The mean age of participants was 6.9 years and 49% were males and 51.3% were females. Giardia lamblia was found in males (10.95%) and females (7.79%). Very low prevalences for Schistosoma mansoni, Ascaris lumbricoides, Taenia species, and Entamoeba coli were detected. Whilst children from mothers (62.2%) and fathers (55.6%) with no education were often infected, a few children from fathers (22.2%) and mothers (6.7%) with no jobs were infected. Most of the infected children's (93.7%) parents did not have any knowledge of IPIs. The educational and employment status of the mothers [p = 1.0 and p = 0.422] was not significant, however, the family size was a predisposing factor (p = 0.031) for parasitic infections.Intestinal parasites were prevalent in children from overcrowded families and with no knowledge of IPIs. Educative programmes on IPIs, improving hygiene, and application of supportive programmes to elevate socioeconomic conditions may help reduce the burden of intestinal parasite carriage in children.
