Annual Epidemiological Reports (AERs)

ECDC’s Annual Epidemiological Report is available as a series of individual epidemiological disease reports. Reports will be published as they become available.

Starting with the annual reports based on 2015 data (and published during 2017), this change is also reflected in the titles: reports will no longer be named after the year of publication; instead, the year given in the title (i.e. 'Annual epidemiological report for 2015') refers to the year the data were collected.

All reports on this page are based on data retrieved from TESSy.[1] Countries participating in disease surveillance submitted their data electronically.

The communicable diseases and related health issues covered by the below reports are under European Union and European Economic Area disease surveillance [2],[3],[4],[5],[6]. 

ECDC’s annual surveillance reports provide a wealth of epidemiological data to support decision-making at the national level. They are mainly intended for public health professionals and policymakers involved in disease prevention and control programmes.
