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

Abstract

Urine samples were assayed for urinary schistosomiasis in four local government areas (LGA) of Imo State, Nigeria between May 1998 and September 2000. A total of 3504 persons were sampled, with 880 (25.1%) being positive for urinary schistosomiasis, based on records of eggs of Schistosoma haematobium. The prevalence of S. haematobium infection differed in the various LGAs, with Oguta (38.9%) and Owerri-West (10.4%) showing the highest and the lowest values, respectively. Prevalence was higher in males (67.4%) than in females (32.6%) and in subjects 11-20 years of age (31.5%), while prevalence varied among different occupational groups, with farmers ranking the highest (41.6%). Visible haematuria was the predominant symptom (P<0.05). Of 880 persons positive for eggs of S. haematobium, 452 (51.4%) had visible haematuria, followed by suprapubic pains 214 (24.3%) and painful micturition 97 (11.0%). Although 367 (10. 5%) of the sampled subjects with eggs of S. haematobium showed no visible haematuria, 513 (14.6%) clearly demonstrated haematuria.

“…A recently conducted study in two rural communities in the same area reported a similar prevalence of 47% (Oladejo & Ofoezie 2006), indicating that infection has remained unabated in this and, most likely, other dam regions of Nigeria. Age and sex-related prevalence and the intensity of infection in the present study were similar to those reported from other West African endemic foci (Okoli & Odaibo 1999, Mafe et al 2000, Okoli & Iwuala 2004, Oladejo & Ofoezie 2006.…”

“…The predominant species in this country is Schistosoma haematobium, which most commonly presents with haematuria, suprapubic pain and pain while urinating (Okoli & Iwuala 2004).…”

Prevalence and risk factors of Schistosoma haematobium infections among primary school children in Igbokuta Village, Ikorodu North Local Government, Lagos State.

“…Studies in Nigeria among school aged children in various parts of the country and in both rural and urban environments have shown that S. haematobium is clearly a problem of this age group. Prevalence among school aged children ranges from 20-40 % in typical communities 4,5 , but can be as high as 50-70 % in areas where environmental changes occur due to constructions such as human-made dams and quarries 6,7 . In Ogun and Lagos State, urinary schistosomiasis has been reported in several communities [8][9][10][11][12][13][14][15] .…”

“…This is explained by the reduction of exposure to contaminated water [10]. On the contrary females, besides being more infected, presented a pattern of infection highest in the intermediate age group (25-34).…”
