Recital 5

(5)Regulation (EC) No 851/2004 of the European Parliament and of the Council of 21 April 2004 establishing a European Centre for Disease Prevention and Control ⁴ (‘ECDC’) provides the ECDC with a mandate covering surveillance, detection and risk- assessment of threats to human health from communicable diseases and outbreaks of unknown origin. The ECDC has progressively taken over the epidemiological surveillance of communicable diseases and the operation of the Early Warning and Response System (‘EWRS’) from the Community network set up under Decision No 2119/98/EC. Those changes are not reflected in Decision No 2119/98/EC, because it was adopted before the establishment of the ECDC.
