A National Computer-Based Epidemiological Information System

A computer-based system for epidemiological information has been worked out on the basis of the existing system for obligatory registration of all persons suffering from infectious diseases. The system consists of two subsystems 1. for descriptive epidemiological information and 2. for analytical epidemiological information.The first subsystem is based on the daily input of registered cases and supplies the necessary information on the epidemic situation of the country by diagnoses, towns and villages, regions and districts, new cases and deaths.Using the data of epidemiological research and the results of medical treatment, the second subsystem meets the demands for data for the regular annual epidemiological analyses. The information collected is analytically evaluated, throwing light upon the factors determining the epidemic situation of the country and making it possible to develop a strategy for the control of infectious diseases and to obtain a model of the epidemic process.
