Soil-transmitted helminth infection among school-age children in Ogoja, Nigeria: implication for control.

The study aimed at assessing the prevalence and risk factors of soil-transmitted helminthiases among school-aged children in Ogoja Local Government Area, Cross River State. Fecal samples were collected from 504 participants and analyzed using the Kato-Katz technique and modified Baermann technique for identifying larvae of Strongyloides. A total of 232 (46.0%) samples were positive for soil-transmitted helminths. The overall prevalence of Ascaris lumbricoides, hookworm, Trichuris trichiura, and Strongyloides stercoralis were 14.1%, 16.5%, 2.6%, and 12.9% respectively. The prevalence of infections were higher among males (46.6%) than females (45.4%). Overall, parasitic infection was higher in the 5-7-year age group (65.6%) than in the other age groups (p = 0.000). Infection intensities of A. lumbricoides (84.00 EPG) (p = 0.044) and T. trichiura (96.00 EPG) (p = 0.041) were higher in school-age children aged 14-16 years. A. lumbricoides and hookworm co-infection (8.7%) was the most common mixed infection and was significantly higher in males than females. School-aged children who did not have prior knowledge about soil-transmitted helminth infections, the habit of drinking water without boiling, open defecation, use of pit latrine, and children who did not have toilet facilities in school were significantly associated with soil-transmitted helminthiases. There was a significant relationship between washing hands after using the toilet, the habit of putting on footwear outside the house, and soil-transmitted helminth infection. In addition to preventive chemotherapy, control measures should focus on health education, providing clean drinking water, proper disposal of human excreta and sewage, and environmental hygiene.

Lymphatic filariasis baseline survey in two sentinel sites of Ogun state, Nigeria.

INTRODUCTION: In preparation for Mass Drug Administration by National Lymphatic Filariasis Elimination Programme, a baseline epidemiological investigation on lymphatic filariasis (LF) was conducted in two sentinel sites of Ogun State, Nigeria. The study was carried out in Ado-Odo Ota and Abeokuta South Local Government Areas (LGAs) to determine LF prevalence, microfilarial density and the abundance of Wucheraria bancrofti in the mosquito vectors. METHODS: Microscopic examination of thick blood smears of 299 and 288 participants from Ado-Odo Ota and Abeokuta South LGAs was conducted. Visual observations of clinical manifestations of chronic infection and questionnaire administration were also conducted. Indoor resting mosquitoes were collected using the pyrethrum spray technique and CDC light traps and mosquitoes were dissected for filarial larvae. RESULTS: Microfilaria prevalences were 4.0% and 2.4% in Ado-odo Ota and Abeokuta South LGAs. The microflarial density (mfd) was 30.6mf/ml and 23.9 mf/ml in the same areas. No clinical manifestations of the infection were found at both sites. Knowledge of LF by inhabitants was very low in the two areas. Anopheles gambiae s.l and Culex species mosquitoes were collected but none was found positive for stage L3 infective larvae. CONCLUSION: Mass awareness campaigns on the goal of mass drug administration, cause of LF, mode of transmission, the relationship between infection and clinical signs/symptoms is advocated so as to increase acceptance and support of the control programme by the community.

Strengthening primary healthcare through community involvement in Cross River State, Nigeria: a descriptive study.

INTRODUCTION: In preparation for implementation of primary healthcare (PHC) services in Cross River State, a study to identify perceptions of communities and health systems concerning such interventions was conducted. METHODS: Existing PHC practices were documented through observation and document reviews, including facility checklists at frontline levels. Perceptions of consumers and providers on PHC were elucidated through 32 Focus Group Discussions (FGDs) and 78 semi-structured questionnaires. RESULTS: There was some level of implementation of the Nigerian PHC policy in the study districts. However, this policy emphasized curative instead of preventive services. Private partners perceived healthcare programmes as largely donor driven with poor release of allocations for health by government. CONCLUSION: Both providers and consumers presented similar perceptions on the current PHC implementation and similar perspectives on services to be prioritized. These common views together with their on-going participatory experience are important platforms for strengthening community participation in the delivery of PHC.
