ENDIG: Interactive Geovisualization of Surveillance Systems for Notifiable Diseases in Europe

Abstract. National disease surveillance systems are among the most important tools for the observation and management of communicable diseases. They help to detect outbreaks and monitor the success of public health responses. The European Union aims to harmonize the European landscape of disease surveillance systems for better interoperability across the member states. However, the progress of these efforts is difficult to assess, as information is available in different formats, written reports or numerous tables for individual diseases. Here we present ENDIG, an interactive geovisualization tool, that makes the existing information easily accessible to end users and researchers in public health and adjoining disciplines. ENDIG allows for convenient exploration about the development of national disease surveillance systems for more than 60 diseases in the EU member states, as well as Iceland, Liechtenstein and Norway, over the course of the past 7 years (2015–2021).
