Abstract
This paper describes an information system (IS) established in France in 1984 for the national surveillance of communicable diseases. This IS is based on a videotex server and a relational database management system. The videotex server is the IS front-end. It performs the following functions: interpersonal communications, synthetic information retrieval into an epidemiologic info-base and data entry owing to its specialized applications. The relational database management system allows the user to manage and consult an epidemiologic database updated in quasi-real time. Several specific tools have also been developed in order to enhance data representation and analysis and the decision support capabilities of the IS.
