Figure 6

Screenshot of Epi Map (part of US CDC Epi Info) [17] showing all premises of environmental health interest (cooling towers, decorative fountains etc) in a buffer of 200 meters around a hypothetical case of legionnaires' disease in the central section of Athens depicted by a blue square (patients' residence). The dark red dots and dark pink colored dots represent the premises, which received inspection score A and B, respectively (satisfactory results). The light pink colored dots represent the premises with the worst inspection score (score C – unsatisfactory results). GIS map features included the ability to review, in real time, the inspection scores and laboratory results by selecting specific items within the buffer zone.
