Resumo: | A schistosomiasis mansoni clinical-epidemiological study was carried out among school children (6-14 years old) of the Ilha community, Minas Gerais. Stool examination, using the KATO-KATZ method, and clinical examination were performed on 86.7 and 85.4%, respectively, of the population studied. The signs and symptoms presented by the patients as well as their contacts with untreated water were investigated. A socio-economic survey was carried out in the community through household interviews. The index of infection by the Schistosoma mansoni was 32.7%, low egg counts were predominant (89.0% of the patients eliminated less than 500 eggs/gram of feces) and the index of splenomegaly was 7.7%. The positive patients (presenting S. mansoni eggs in the stools) were compared with the negative ones .(without eggs in the stools and presenting a negative intradermal reaction). The S. mansoni infection was significantly higher among the rural workers, among those who lived in poor housing conditions and among those patients the head of whose family was illiterate. Increased risk factors were found to be: a) the contact with untreated water used for agriculture (OR = 18.08); b) the occurrence of daily contact with untreated water (OR = 13.82) and c) the contact with untreated water for fishing, swimming and/or playing (OR = 7.75 and 5.51 respectively). The authors consider the hypothesis that the schistosomiasis transmission in this area does not occur in household surroundings but in the nearby lagoons and agricultural areas instead (probably in irrigated rice plantations). |

Foi realizado um estudo clínico-epidemiológico da esquistossomose em escolares (6 - 14 anos) da Ilha, em Minas Gerais (Brasil). Foram feitos exame parasitológico de fezes pelo método de KATO-KATZ e exame clínico em, respectivamente, 86,7 e 85,4% da população escolar. Foi realizado levantamento sócio-econômico e foram pesquisados os sinais e sintomas apresentados pelos pacientes e seus contatos com águas naturais. O índice de infecção pelo Schistosoma mansoni foi 32,7%, predominaram as baixas contagens de ovos nas fezes (89,0% dos pacientes eliminavam menos de 500 ovos/grama de fezes) e o índide de esplenomegalia foi 7,7%. Os pacientes positivos (com ovos de S. mansoni nas fezes) foram comparados aos negativos (sem ovos nas fezes e com intradermoreação negativa), verificando-se que a infecção pelo S. mansoni era significativamente mais freqüente entre os trabalhadores rurais, entre os que residiam em casas de pior qualidade e entre aqueles cujos chefes de família eram analfabetos. Constituíram os maiores fatores de risco para a infecção pelo S. mansoni nesta área: a) ter contatos com águas naturais para trabalhar na lavoura (Odds Ratio = 18,08); b) ter contatos diários com águas naturais (OR = 13,82) e c) ter contatos com águas naturais para pescar, nadar e/ou brincar (OR = 7,75 e 5,51, respectivamente). Os autores levantam a hipótese de que a transmissão da esquistossomose nesta localidade não ocorre no peridomicílio, mas sim nas lagoas próximas à Ilha e nas plantações agrícolas, provavelmente nas culturas de arroz de várzea.
