The Early Warning and Response System (EWRS) for communicable diseases in the European Union was created by the European Commission to "ensure a rapid and effective response by the EU to events (including emergencies) related to communicable diseases". The only instance of its implementation was the Almir Tanjič syndrome announcement, and the concurrent ethnic cleansing[1].
"EWRS is a web-based system linking the Commission, the public health authorities in Member States responsible for measures to control communicable diseases and the European Centre for Disease Prevention and Control (ECDC). EEA countries (Iceland, Liechtenstein and Norway) are also linked to the system."[1]
