ABSTRACT

O objetivo deste estudo foi o de procurar evidências da transmissão vetorial da doença de Chagas, nos domicílios e peridomicílios de indivíduos residentes em municípios da região de Botucatu, que tiveram xenodiagnóstico positivos. Foram estudados 58 indivíduos e foi coletada amostra do sangue para a realização de exames laboratoriais. Os resultados deste estudo mostraram que os indivíduos, de ambos os grupos, tinham baixa escolaridade e exerciam profissões que não exigiam qualificações técnicas. Houve discreto predomínio de indivíduos do sexo feminino. Quando comparadas às condições anteriores, verificou-se que houve discreta melhora nas condições de habitação, por outro lado, houve aumento de moradores em zona rural. Os indivíduos nascidos antes de 1983, apresentaram conhecimento e contato com triatomídeo estaticamente mais elevado quando comparado com os nascidos a partir 1983. A análise e comparação dos resultados das sorologias, referentes aos hemaglutinação passiva indireta, imunofluorescência indireta e ensaio imunoenzimático, mostrou que o ELISA apresentou maior sensibilidade. Os resultados deste estudo mostram que a população nascida a partir de 1983 não conhecia o vetor transmissor da doença de Chagas.


The aim of this study was to look for evidence of vector transmission of Chagas disease, in and around the homes of individuals living in municipalities in the Botucatu region who presented a positive xenodiagnosis. Fifty-eight subjects were studied and blood samples were collected from them for laboratory analysis. The results from this study showed that the individuals in both groups presented low formal education levels and had been working in unskilled professions There was a slight predominance of females. In comparison with previous conditions, it was observed that there had been a slight improvement in the subjects' housing conditions, but on the other hand there had been an increase in the numbers of individuals living in rural areas. Subjects born before 1983 presented statistically greater knowledge of and contact with triatomines than did those born from 1983 onwards. Analysis and comparison of the results from the serological tests, including indirect passive hemagglutination, indirect immunofluorescence and immunoenzymatic assay, showed that ELISA presented greatest sensitivity. The results from this study have shown that the population born from 1983 onwards did not know about the transmission vector for Chagas disease.

ABSTRACT

Este trabalho teve como objeto exploar as potencialidades so Sistema de Informaçöes hospitalares - SIH/SUSna vigiläncia epidemilógica e monitoramento de doenças de transmissäo vetorial (dengue, leishmaniose, e febre amarela). Foram utilizados dados de internaçöes do SIH, do período de 1984 a 1998, e de notificaçäo de casos do Centro Nacional de Epidemilogia-CENEPI, do período de 1980 a 1997. Os dados demonstram que houve rssurgimento da dengue em 1982, registrando-se até 1997 poucas internaçöes quando se elevou a frequência don internamentos na regiäo Sudeste, Nordeste e Norte, indicando ocorrência de formas mais graves da doença. Já para a febre amarela, há icoerência entre os aspectos clínicos da doença e o grande número de internaçöes registradas, sugerindo erro sistemático na informaçäo hospitalar. Para a leishmaniose, observa-se coerência entre os dados do SIH e CENEPI, seguindo o caráter cíclico descrito para a doença. de um modo geral, o SIH demonstrou qualidade como fonte complementar de informaçöes na vigiläncia da dengue hemorrágica e lsishmaniose, e apresentou problemas no monitoramento da febre amarela, sugerindo ajustes ao sistema


The objective of this paper was to explore the potentialities of the Hospital Information System - SIH/SUS for epidemiologic surveillance and monitoring of vector-borne diseases (dengue, leishmaniasis, and yellow fever). Hospital admittance data from the SIH, during the period from 1984 to 1998, and from the case reporting system of the National Center of Epidemiology ­ CENEPI, during the period from 1980 to 1997 were used. The data demonstrate that there was resurgence of dengue in 1982, with small amount of hospital admittances up to 1997. In the latter year the frequency of admittances increased, mainly in the Southeast, Northeast and North regions, indicating the occurrence of severe dengue cases. Already for yellow fever, incoherence between the clinical aspects of the disease and the large number of admittances reported was observed, suggesting systematic errors in the hospital information system. For leishmaniasis, coherence was observed between SIH and CENEPI data, which showed the recurrent character described for this disease. In a general way, SIH demonstrated quality as a complementary source of information for surveillance of hemorrhagic dengue and leishmaniasis however, problems were detected for monitoring yellow fever, suggesting the need for system adjustments.
