  1. Pattern analysis of human salmonella enteritidis infection.

    Article - En anglais

    Information on salmonella serovar, community, and date of isolation concerning 10368 cases of S. enteritidis (SE) infection and 1163 cases of S. typhimurium (ST) infection reported in 1992 to the Salmonella Data Bank of the Land of Brandenburg have been analyzed for clusters and trends on case/time diagrams.

    A breakdown by district provided a suitable degree of « resolution » for discrimination of « Episodes of Increased Case Frequency » (EICF) and 7 days moving averages.

    Thus 39 of the 44 districts of the Land were included in the evaluation of SE cases.

    The population size of the remaining 5 districts was too high for clear episode discrimination.

    EICFs were subdivided into (a) 16 outbreaks (another 10 outbreaks occurred outside EICFs), which had also been identified and officially reported by local health services as a result of compulsory investigation of cases and their social environment, and (b) 44 « case accumulations » (ACCs), which were only identified by retrospective analysis of the case/time diagrams.

    By this procedure, three case categories of distinct properties have been found for SE transmission from the animal reservoir to the human population : outbreaks, ACCs, and « truly sporadic cases » scattered over the district outside outbreaks and ACCs (Table 3).

    Truly sporadic cases (Table 6) represented the largest proportion of SE cases.

    ACCs accounted for 37% and outbreaks, for 12%.
