Examples for the use of EpiScanGIS. (A) For the years 2004 and 2005, a query was made for a very frequent meningococcal serogroup B fine type (B:P1.7-2,4:F1-5), whose distribution (circles) is compared with all serogroup B cases (triangles) in the database. Note that serogroup B cases due to this fine type are mostly found in the Western part of Germany. (B) Section of the EpiScanGIS screen display: a spatio-temporal cluster is depicted by a circle surrounding the location of cases due to a certain fine type (B:P1.7-2,4:F1-5), which are in close spatio-temporal proximity. A description field provides additional information on the cluster. Temporal information has been obscured for the purpose of publication.
