WHO is the United Nations specialized agency for health. The WHO European Region covers 53 Member States. All 27 EU members are among them, as well the groups of the accession/potential candidate countries, those covered by the European Neighbourhood Policy and the Central Asian Republics. The WHO Regional Office for Europe is based in Copenhagen. The Brussels office is its official representation to the EU, with a function of liaising with all relevant EU stakeholders and keeping WHO/Europe in the centre of the European health debate, with an equally high interest in the policies being developed and implemented in the health and non-health sectors.
