“…Similar results have been reported by other investigators. [8][9][10][11][12][13] Constipation/flatulence was found to be associated with S. mansoni infection in the present study, though Gremillion 8 did not observe this in infected Saudi Arabian recruits in the U.S.…”

“…Many investigators have stressed the importance of the quantitative estimation of intensity of infection in relation to the epidemiological and clinical studies of S. mansoni infection. 9,10,14,17,21,25 The present study shows that the occurrence of abdominal pain, constipation/flatulence, and fatigue shows a greater positive association with intensity of S. mansoni infection for all age groups compared to noninfected control subjects. Various investigators have noted the positive association of abdominal pain with S. mansoni infection.…”

“…This agrees with findings reported by other investigators from other countries. 10,12,17,[19][20][21]27,28 Longitudinal studies are urgently needed in Saudi Arabia on some morbidity aspects of both S. mansoni-and S. haematobium-infected persons, with an ultimate aim of mitigating the morbidity due to schistosomiasis.…”

The morbidity of schistosomiasis mansoni in the Hijaz highlands was investigated in relation to the intensity of infection among a group of 162 patients. Of these, 58.6% showed light infection, 26.52% moderate infection, and only 14.9% heavy infection. The morbidity parameters in these patients were compared to a normal noninfected group of 161 persons residing in Jeddah (nonendemic area). Fatigue, abdominal pain, and constipation occurred more frequently among infected patients. There was a positive relationship between these symptoms and the intensity of infection. Fatigue was observed more frequently among patients older than 21 years, suggesting that this symptom increases with age. Abdominal pain and constipation showed an equal distribution between the under and over 20-years age groups. Hepatomegaly and splenomegaly were somewhat more frequent among patients with high-intensity infection.AM Ghandour, AA Al-Robai, M Doenhoff, AA Banaja, Morbidity from Schistosoma Mansoni in Relation to Intensity of Infection in a Community-Based Study. 1990; 10(4): 420-425 Human infection with Schistosoma mansoni has been reported from several localities in Saudi Arabia and exhibits a patchy distribution that ranged between 0 and 90%.

“…In our study, hepatomegaly below the costal margin was detected in similar percentages in in- fected and uninfected people. However, it is complicated to compare our results with those obtained in other epidemiological settings, because the diagnosis of clinical hepatomegaly has not been standardized (Cook et al 1974, Lehman et al 1976). Moreover, it is possible that not all cases of clinical hepatomegaly found in this work could be explained by schistosomiasis.…”

“…Its wide geographic distribution, the high number of infected people and the possibility of its de velopment into a severe form emphasize its importance as a public health problem. Many Authors throughout the world 2,4,5,6,18,20,22,26,27,30 have pointed out the need of epidemiolo gic studies regarding schistosomiasis mansoni in endemic areas, in order to better evaluate its, natural history and the real impact the dis ease might have on populations.…”

SUMMARYA population-based clinical epidemiologic study on schistosomiasis mansoni was carried out in Tuparece, Minas Gerais. The patients were interviewed for symptoms, water contact, past history and examined for spleen and liver enlarge ment. From the 830 people registered in the census, 777 (93.6%) had their stools examined (Kato-Katz method) and 696 (83.9%) were clinically evaluated. The overall index of Schistosoma mansoni infection was 43.2%. Significant and increased infection risks could be detected in the young age group (2-14 years old) regarding occupation, time of residence in the area and frequency of water contact. Bloody stools were significantly more prevalent among positives, while diarrhea was significantly more prevalent among those negative. The area was shown to have a low morbidity as well as a low intensity of infection measu red by the number of S. mansoni eggs per gram of feces. A close correlation was found between water contact pattern and the age prevalence curve. It has empha sized the importance of habits in determining prevalence rates, besides suggesting that schistosomiasis mansoni in the area is manifested as a light and somewhat harmless infection with little consequence for the population as a whole.
