EWARS in a box: electronic early warning, alert and response system implementation in emergencies

EWARS in a box, WHO's electronic early warning, alert, and response system in emergencies, helps detect disease outbreaks early in emergency, fragile, conflict and vulnerable settings. It supports real-time mobile reporting from the most difficult and remote field settings with or without reliable internet or electricity. The web interface helps local epidemiologists and surveillance officers with interactive alert management, data analysis and visualization. The 16 multilingual online training package provides epidemiologists, surveillance officers and emergency responders with a comprehensive overview of establishing EWARS in a box in the field with the key features and functionalities of the tool.
