Department of Health (DH) - The Global Health Security Agenda is a US-led initiative to make progress, through international collaboration, toward a world safe and secure from infectious disease and other health threats. The UK volunteered to pilot an assessment tool designed to assess how countries are performing against the national actions and targets set out in 11 action packages spanning prevention, detection and response preparedness. This report follows a self-assessment and a week-long assessment visit to the UK in June 2015 by a panel of international experts. The report concludes that, overall, the UK has demonstrated a strong baseline position across all areas. One key area of strength was the cross-government and organisational coordination and response to the Ebola crisis.
