“…The preponderance nature of Ascaris lumbricoides infections in this study corroborates with findings from recent epidemiological surveys [12,16]. Ascaris lumbricoides infections were observed in 19 of the 20 LGAs studied, with increased prevalence in the western part of the state.…”

Background Ascariasis, Trichuriasis and Hookworm infections poses a considerable public health burden in Sub-Saharan Africa, and a sound understanding of their spatial distribution facilitates to better target control interventions. This study, therefore, assessed the prevalence of the trio, and mapped their spatial distribution in the 20 administrative regions of Ogun State, Nigeria. Methods Parasitological surveys were carried out in 1,499 households across 33 spatially selected communities. Fresh stool samples were collected from 1,027 consenting participants and processed using ether concentration method. Households were georeferenced using a GPS device while demographic data were obtained using a standardized form. Data were analysed using SPSS software and visualizations and plotting maps were made in ArcGIS software. Results Findings showed that 19 of the 20 regions were endemic for one or more kind of the three infections, with an aggregated prevalence of 17.2%. Ascariasis was the most spatially distributed found in 28 communities, with 140(13.6%) infected subjects, followed by Hookworm infection in 19 communities, with 47(4.6%) infected subjects and Trichuriasis in 9 communities, with 17(1.7%) infected subjects. The spatial distribution of infections ranges between 5.3 – 49.2% across the regions. The highest and lowest distribution was recorded in Yewa South and Yewa North respectively. By WHO preventive chemotherapy thresholds, 9 regions had infection status between 20.0%-49.2%, while 10 regions had infection status between 5.3%-15.8%. Conclusion This study provides information on the prevalence and spatial risk of Ascariasis, Trichuriasis and Hookworm infection that will serve as decision-support tool to help facilitate targeting of control interventions.

“…In Nigeria, research findings on the geospatial distribution of Ascaris, Trichuris and Hookworm infections are scarce, but emerging [11,12,13]. This study therefore adds to the wealth of existing data on spatial distribution of these infections in Ogun State, Nigeria.…”

“…Hookworms were the most prevalent and the most widespread STH parasite in Kogi East. A similar observation was reported in Ogun State, Nigeria [31,38]. The authors attributed this to the location of Nigeria in the equatorial zone with favorable environment for the development of the larvae of hookworms.…”

“…The overall prevalence of A. lumbricoides in this study was lower than what was observed in school-age pupils of rural areas of Southern China (18.5%) [34]; southern rural Lao People's Democratic Republic (PDR) (27.4%) [35]; Jimma, Ethiopia (23.6%) [25]; Zana wereda, Ethiopia (11.5%) [4]; Ogun State, Nigeria (29.3%) [31]; and Jos, Nigeria (25.7%) [32]. The possible reason for the higher prevalence in those studies compared with this study could be that the environment of where those studies were carried out may be more favorable for completion of the life cycle of the parasite such as fertile soil, and humid and wet environment.…”

“…This study revealed that STH infections remain a major public health problem in Kogi State and are prevalent among schoolchildren in the rural communities of Kogi East [22]. The overall prevalence of STHs observed in this study was higher than that observed in Chencha town, Ethiopia (2.2%) [23]; Were-abaye, Ethiopia (12.22%) [24]; Babile town, Ethiopia (13.8%) [25]; Zana wereda, Ethiopia (12.7%) [4]; and Cameroon (6.3%) [26]; but lower than that observed in Adwa town, Ethiopia (69.0%) [27]; Lumame town, Ethiopia (54%) [28]; Northern Gondar, Ethiopia (66.7%) [29]; Zegie Peninsula, Ethiopia (69.1%) [30]; Jimma, Ethiopia (45.6%) [25]; Ogun State, Nigeria (34.6%) [31]; and Jos, Nigeria (42.6%) [32]. They attributed the differences in prevalence to the topography of the study areas, living standards, as well as personal and environmental hygiene of the communities studied.…”

Soil-transmitted Helminths (STHs) are one the leading causes of global health problems especially in poorest and deprived communities where implementation and control are difficult to maintain. Soil-transmitted helminthiasis is caused by parasitic nematodes transmitted through contact with parasites eggs (Ascaris lumbricoides and Trichuris trichiura) or larvae (hookworms) and are responsible for more than 40% of worldwide morbidity from all tropical infections [1-3]. A recent report estimated that 2 billion people are infected with STHs worldwide, with 819, 439, and 439 million people infected with A. lumbricoides, T. trichiura, and hookworms, respectively [3,4]; about 610 million school-age children are at risk of infection with STHs [4].

The study aimed at assessing the prevalence and risk factors of soil-transmitted helminthiases amongst school-aged children in Ogoja Local Government Area, Cross River State. Faecal samples were collected from 504 participants and analysed using the Kato-Katz technique. 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 signi cantly higher in males than females. School-aged children who did not have prior knowledge about soiltransmitted 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 signi cantly associated with soil-transmitted helminthiases. There was a signi cant 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.
