The Division of Communicable Diseases, Environment and Health (CDE) assists country efforts to reduce the burden of communicable diseases and addresses the social, economic and environmental determinants of health, and promotes policies and actions for health through stewardship of the WHO European Healthy Cities Network. It focuses on health promotion measures, behavioural insights; communicable diseases such as tuberculosis, HIV/AIDS and hepatitis, and vector-borne and neglected tropical diseases; elimination and control of vaccine-preventable diseases and advocacy for increased use of vaccines; containing and controlling antimicrobial resistance; addressing existing and emerging environmental health risks and supporting violence and injury prevention. A determination to ensure universal access to people-centred quality health services across the continuum of care is matched by enriching the evidence base for policy design and interventions using social, cultural and behavioural approaches, to drive implementation of innovation at national, regional and local levels.
