Status of hookworm infection in junior secondary students, Bwari Area Council, Abuja, Nigeria

Abstract

Hookworm infection has long been classified as the second most common parasitic helminth disease of the tropic and sub-tropic most especially because besides its grievous public health implications, some of which are due to the pathological damage it causes in the human host’s tissue and organs, the disease also has negative impacts on both human and socio-economic developments in communities where it is endemic. This study aims to verify the prevalence and intensity of hookworm infection in secondary school students in Bwari Area Council, FCT, Abuja. Four secondary schools namely, Government Secondary School, Law School Road, St. Theresa’s Catholic Schools, Government Secondary School, Kuduru and Government Secondary School, Zuma II, were selected randomly as case study. Four hundred and eighty (480) stool specimens (i.e., 120 from each school) were collected exclusively from the Junior Secondary School students of these schools, ensuring that both sexes were equally represented in those to supply the stool specimens. Microscopic examination of the stool specimens was carried out using saline and iodine wet mounts, brine floatation and centrifugation/sedimentation methods to check for presence of ova of hookworm. Result obtained showed that only 167(34.8%) stool specimens contained ova of hookworm of which 107(64.1%) were those from male students and 60(35.9%) were from females. 67(62.6%) were from those within the age bracket of 9-13 years while the other 40(37.4%) were those from 14-18 years age bracket. Similarly, 33(55%) of the infected females were within 9-13 years’ age bracket while the rest 27(45%) were between 14-18 years. Further classification of the result revealed JSS 2 and JSS3 students as having the highest prevalence with 67(40.1%) and 57(34.8%), respectively, while JSS 1 had low infection with 43(25.7%). When infections amongst the schools were compared, it was found that Government Secondary School, Zuma II, had the highest with 48(40%) while the rest Government Secondary School, Law School Road, St. Theresa’s Catholic Schools and Government Secondary School, Kuduru, had 40(33.3%), 36(30%) and 43(35.3%), respectively. the study has confirmed that hookworm exist in Bwari Area Council. The observed high prevalence of infection amongst male students between the 9-13 years age bracket cannot therefore be unconnected with their active engagement in farming, hunting, sports (such as football, athletics, etc.) and other extra-curricular activities that make them expose themselves to unprotected and hookworm-infested soils. Prompt treatment of known cases beside adequate and regular health education campaign in primary, secondary, work places and public markets on the need for proper hygiene practices and regular environmental sanitation and avoidance indiscriminate human faecal disposal.Keywords: Hookworm; prevalence; intensity; secondary school; students; Bwari.
