  1. The dot map as a epidemiological tool : a case study of Schistosoma mansoni infection in an urban setting.

    Article - En anglais

    In this paper dot maps are used as an epidemiological tool to describe the spatial patterns of cases, non-cases and some relevant risk factors associated with the occurrence of Schistosoma mansoni infection in an urban environment.

    The study was carried out in Santo Antonio de Jesus, a town in north-east Brazil with a population of around 45000 inhabitants.

    The survey was targeted at all children aged between 12 years 8 months and 14 years 11 months who were living in the town at the time of the survey.

    An extensive questionnaire was used to collect information on each child and on family and household conditions; stool samples were also taken for quantitative examination.

    A computerized digitizer was used on a map (scale 1:4000) to create x and y coordinates for each child's household.
