Ocorrência de um surto de hepatite A em três bairros do município de Vitória (ES) e sua relação com a qualidade da água de consumo humano / Occurrence of a hepatitis A outbreak in three neighborhoods of the city of Vitória, Espírito Santo State, and its relation with the quality of the water for human consumption

Este trabalho teve como finalidade analisar os possíveis fatores relacionados com as ocorrências de hepatite A nos bairros Grande Vitória, Estrelinha e Inhanguetá, localizados no município de Vitória, Estado do Espírito Santo, de abril a junho do ano de 2006, e a qualidade da água consumida pela população. Foram usados como indicadores de qualidade da água as concentrações de cloro residual livre (CRL) e a presença de coliformes termotolerantes. As análises microbiológicas realizadas na água consumida pelas comunidades estudadas não apresentaram resultados indicadores de contaminação por coliformes termotolerantes e os teores de CRL determinados nos meses de janeiro a junho estiveram sempre acima do limite mínimo exigido pela legislação (Portaria nº 518/2004). Os resultados mostraram que a ocorrência do surto de hepatite A pode estar relacionada com a ausência de barreiras físicas que impeçam o contato das pessoas com água contaminada e às deficiências nas práticas higiênicas adotadas, individualmente, pela população local.

This work had as purpose to analyze the possible factors related with the occurrences of Hepatitis in the neighborhoods of Grande Vitória, Estrelinha and Inhanguetá located in the city of Vitória, State of the Espírito Santo, from April the June, 2006, and the quality of the water consumed by the population. The indicators for the water quality used were the Free Residual Chlorine concentrations (FRC) and the presence of thermotolerant coliforms. The microbiological analyses performed in the water consumed for the studied communities did not presented results indicating contamination by thermotolerants coliforms and the percentage of FRC determined between January and June were always above of the minimum limit demanded by the legislation (Act 518/2004). The results showed that the occurrence of a Hepatitis A outbreak can be related with the absence of physical barriers that impede the contact of people with the contaminated water and the practical deficiencies in the hygienic practices adopted, individually, by the local population.
