Epidemic intelligence: a new framework for strengthening disease surveillance in Europe

Abstract

In a rapidly changing environment, national institutions in charge of health security can no longer rely only on traditional disease reporting mechanisms that are not designed to recognise emergence of new hazards. Epidemic intelligence provides a conceptual framework within which countries may adapt their public health surveillance system to meet new challenges. Epidemic intelligence (EI) encompasses all activities related to early identification of potential health hazards, their verification, assessment and investigation in order to recommend public health control measures. EI integrates both an indicator-based and an event-based component. ‘Indicator-based component’ refers to structured data collected through routine surveillance systems. ‘Event-based component’ refers to unstructured data gathered from sources of intelligence of any nature. All EU member states have long-established disease surveillance systems that provide proper indicator-based surveillance. For most countries, the challenge lies now in developing and structuring the event-based component of EI within national institution in charge of public health surveillance. In May 2006, the European Union member states committed to comply with provisions of the revised International Health Regulations (IHR(2005)) considered relevant to the risk posed by avian and potential human pandemic influenza. This provides for the European Centre for Disease Prevention and Control (ECDC) with an opportunity to guide member states in developing and/or strengthening their national EI , in addition to the ECDC’s task of developing an EI system for the EU.

“…Epidemic Intelligence (EI) is an automated early identification of health threats and disease outbreaks, their verification and risk assessment and investigation to inform health authorities about the required measure to protect the citizens [2,3,4]. This is of a particular concern in situations of mass gatherings (e.g.…”

“…Sus salidas son el boletín semanal y la publicación Eurosurveillance, mediante una "alerta electrónica." 43 Se destaca como sistema ya consolidado en la región el British Paediatric Surveillance Unit (BPSU) iniciado en el Reino Unido e Irlanda, el que tiene como objetivo la vigilancia de condiciones raras e infecciones en la infancia (0 a 15 años). Esta red ahora cubre 14 países (8 dentro de la Unión Europea).…”

From SARS to Ebola – 10 years of disease prevention and control at ECDC

“…In its second year of operations, ECDC presented a proposal to complement the traditional indicator-based surveillance, using epidemic intelligence as an early detection and warning system [4]. Such epidemic intelligence would take into account changes in the information sector, and pick up relevant information from sources such as traditional and social media and others, and analyse it.…”
