EpiSignalDetection is a tool for detection of epidemiological signals. Public health experts and epidemiologists can use the tool to detect signals for outbreaks, based on changes in disease incidence.
EpiSignalDetection is an R package, which analyses surveillance data to identify any fluctuations in disease incidence, which might indicate early warning signs for outbreaks. Statistical methods are applied to analyse observed infectious diseases surveillance data collected by ECDC at the EU/EEA or country level. The tool includes:
- Signal Detection tool, an interactive 'shiny' application in which the user can import external data and perform basic signal detection analyses;
- An automated report in HTML format, presenting the results of the time series analysis in tables and graphs. The report can also be stratified by population characteristics (see 'Population' variable).
The software is available as an R package under European Union Public Licence v.1.2 EUPL © the European Union 2007, 2016.
R was chosen as the computing platform, to make the tool as broadly available as possible, as it is free, open source, and runs on any modern operating system.
To use an R package, R must first be downloaded and installed on your computer.
