Abstract(s)
A pesquisa teve como tema “Doenças Negligenciadas e Desenvolvimento Econó- mico e Social”: o caso da Schistosomose em Cacula (Huíla-Angola). Oito comunidades foram envolvidas (N=1174), numa abordagem descritiva, assumindo em alguns momen- tos um carácter explicativo. Além do inquérito, os participantes dispuseram amostras de excretas (fezes e urina), o que permitiu pesquisar evidências de S. mansoni e S. haema- tobium respectivamente.
A relevância da pesquisa no Município centrou-se no facto da Schistosomose existir e não ser conhecida a sua incidência concreta. Ademais, as doenças impedem a realiza- ção cabal de actividades económico-produtivas – uma verdade que aumenta a vulnera- bilidade e pobreza das famílias.
Na perspectiva do presente estudo não existe S. mansoni em Cacula, porquanto as análises em fezes foram negativas. Enquanto isso, 22,1% das amostras de urina (N=1174) foram positivas, concluindo-se que o S. haematobium é o prevalente no Mu- nicípio. A maior incidência registou-se em crianças (47,5%) dos 4 aos 10 anos de idade.
A inexistência de uma rede de abastecimento de água e o precário saneamento básico do meio, constituem os principais factores que favorecem a presença da doença, sem olvidar as condições ambientais locais que propiciam o desenvolvimento do hospedeiro intermediário (caracol).

The research issue was “Neglected diseases and Socio-Economic Development”: the study case of Schistosomiasis in Cacula (Huíla-Angola). Eight communities were involved and 1174 persons contributed to it, in a descriptive approach which sometimes took an explanatory profile. In addition to the enquiry, the participants also provided feces and urine for the diagnosis of S. mansoni and S. haematobium, respectively. The relevance of the research was based on the knowledge of the presence of Schisto- soma however, its rate in the municipality was not known, and additionally on the loss of productive in the economic activities - a situation which increases the vulnerability and economic deprivation of families. In the current study, S. mansoni was not found in Cacula, since the stool analysis were negative. Meanwhile, 22,1% of urine samples (n=259) were positive for S. haematobium, leading therefore to the conclusion that this parasite is prevalent in the municipality. The children from 4 to 10 years old presented the highest prevalence (47,5%). The nonexistence of a water supply network and poor sanitation are the main risk factors that favor the presence of the disease, together with the local environmental conditions that are enabling the development of the host (snail). Keywords: Schistosomiasis; Schistosoma haematobium, Cacula; Neglected diseases; Rural development.
