Global Capacities Alert and Response

The WHO Department of Global Capacities Alert and Response (GCR) leads the global community in developing a global framework to detect, assess and provide a coordinated response to events that may constitute a public health emergency of international concern, in line with the International Health Regulations (2005).



In developing, strengthening and maintaining this global framework, GCR focusses on the following:

  • Supporting the development of strong national public health systems including in the area of travel and transport, to maintain active surveillance of diseases and public health events, rapidly investigate reports, assess public health risks, share information; and implement public health control measures in response to public health events that may constitute a public health emergency of international concern.
  • Further developing and maintaining an effective international system that is able to continuously assess the global context of public health risks (global risk assessment) and is prepared to respond rapidly to unexpected, internationally‐spreading events and to contain specific public health threats.
