Epidemic intelligence and travel-related diseases: ECDC experience and further developments

The European Centre for Disease Prevention and Control (ECDC) started to work on information gathering for early detection of public health threats in June 2005. Since then, based on a framework including events and data-based surveillance, EDCD has been learning by doing. The internal tools and procedures for epidemic intelligence (EI) were developed while screening signals. Information including relevant epidemiological data, media news detected and actions taken are recorded in a specific event information system (Threat Tracking Tool). We describe the main elements, process and outputs of EI activities at ECDC. We also describe the main results regarding travel-related diseases. Efforts are needed to better identify and gather information about travellers coming to the EU with imported diseases with a potential for further spread inside our territory.
