ResumoThe objective of this study was to identity biological and social risk factors for the occurrence of microfilaraemia in a population of 1464 children of both sexes aged 5–14 years, living In two highly endemic areas of Recife a city in the northeast of Brazil. A survey was performed from December 1990 to July 1991 and the microfilaraemia was examined by the thick-drop technique using 45 μl of peripheral blood. Information was obtained about use of bednet, length of time living in area and number of occupants per household. Risk was quantified by the crude and adjusted Odds Ratio. The 95 per cent confidence interval, Likelihood Ratio Statistics, and P value were used to test the statistical significance. An association was established between microfilaraemia in children and adolescents, and age, number of individuals per household, the presence of microfilarnemic adults In the household, length of time living in the area, and bednet use. Maternal microfilaraemia was not found to be a risk factor for the occurrence of mlcrofilaraemla in offspring. These results allow the identification of children with a greater risk of microfilaraemia. In addition, these findings highlight the role of the household environment in the transmission process.
