A study of an outbreak of schistosomiasis in two resttlement villages near Abeokuta, Ogun State, Nigeria

Abstract

Frequent reports of haematuria among resettlers at Ibaro and Abule-titun located close to a newly constructed reservoir. 20 km north-west of Abeokuta. Ogun State, Nigeria. prompted a pre-control survey to assess age and sex distribution of urinary schistosomiasis in the communities. 210 persons were examined at Ibaro and 145 at Abule-titun between April 1988 and February 1989. Overall prevalence was about 80% in both villages, and all age and sex groups examined were affected. The pattern of infection in both villages was similar, prevalence being high in all age and sex groups and, unlike most endemic communities, the rate of infection was not significantly higher among the 5–14 year age groups. Intensity of infection was also high in all age and sex groups with mean range egg output of between 73±73 and 2016±3875 ova/10ml urine at Ibaro and between 231±122 and 1340±1786 ova/10ml urine at Abule-titun. This is attributed to an occupation-related high rate of human water contact in both villages.

The prevalence, intensity and clinical signs of urinary schistosomiasis in Imo state, Nigeria

“…This overall sex differential was more conspicuous in Okigwe, Oguta and Ohaji/Egbema than in Owerri-West. Similar observations were made by Pugh & Gilles (1978) in Malumfashi in northern Nigeria, by Udonsi (1990) in the Igwun River basin of southeastern Nigeria, by Ofoezie et al (1991) near Abeokuta, Ogun State and by Scott et al (1982) around Volta Lake Ghana. As noted by Udonsi (1990), the apparent male bias in prevalence may be due to the predominantly male participation in swamp rice farming, and thus an overwhelming proportion of water-contact activity was taken up by males.…”

Female genital schistosomiasis (FGS) in Ogun State, Nigeria: a pilot survey on genital symptoms and clinical findings

“…It is remarkable that such a locally pervasive disease, which is of obvious detriment to the health of women has not attracted more attention, although like elsewhere in Nigeria many perhaps suffer in silence (Dawaki et al 2015). Surveillance for FGS has been totally overlooked, whilst the disease has been firmly engrained in these communicates for decades, first formally reported in 1991 (Ofoezie et al 1991). More broadly, clinical surveillance of FGS in West Africa has not been undertaken largely due to lack of awareness and inexperience of health personnel at all cadres (Christinet et al 2016;Holmen et al 2016), inadequate resources for its detection within the primary care setting (WHO, 2015), as well as competing interests and priorities within NCPs that tackle more obvious issues associated with administration of preventive chemotherapy.…”

Composition, abundance and diversity of the Family Cichlidae in Oyan Dam, Ogun State, Nigeria

“…It is located 7°15' North latitude and 3°16'East longitude at an elevation of 43.3m above sea level on the confluence of Oyan and Ofiki rivers, both tributaries of Ogun River (Ofoezie et al 1991;O-ORBDA 1998). It has a catchments area of approximately 9,000km² within the southern climatic belt of Nigeria.…”
