Outbreak reports and data

Threats and outbreaks by disease and country

ECDC monitors current infectious disease outbreaks and assesses the risk to public health in Europe. ECDC experts provides technical support to the EU-level response to such threats.

Interim surveillance case definitions for reporting in EU

During outbreaks, ECDC issues draft interim case definitions for surveillance, to support classifying cases for epidemiological reporting in EU.

ECDC in the field

ECDC supports outbreak investigations through deploying ECDC missions, supporting the EU Med Corps and facilitating national experts participation in WHO and other missions.

Outbreak tools

ECDC has produced several tools to support and guide outbreak preparedness, investigation and response activities.

Epidemic intelligence

Epidemic intelligence can be described as the systematic collection and collation of information from a variety of sources. See a list of epidemiological sources and tools used by ECDC
