Abstract
Schistosorniasis is one of the major world health
problems . In Egypt, Schistosomiasis affects 20 million,
12—15 of which are infected with S.mansoni(Lehiian et al.,
1970).
Unforunately, the ill effects of schistosomiasis are under estitoted, as t’iey are late in appearance, and data available on morbidity are derived from hospital admissions and autopsy studies (Mousa et a1, 1967).These studies select the more seriously ill and provide misleading information on the public health significance of schistosomiasis.
There is a real need for morbidity data gathered from community members rather than from haspitilized patients.
Data about the prevalence of complications among the patient infested with schistosomiasis are scanty. During every day practising physician is faced with multiplicity of clinical observation. On one hand, you meet young patient, even, children, presenting with various complications of schistosomiasis, and an the other hand you see an old man with definite history of schistosam— iasis with no trace of ill effect of the disease on his health. Inbetveen these two extremes, you see all stages of the disease and complications with no clear explanation.
This retrospective study was a trial to answer some questions(A) What is the prevalence of complication& among these infected persons.
(B) What are the factors favouring the development of the complications.
