Defining collaborative surveillance: a core concept for strengthening the global architecture for health emergency preparedness, response, and resilience (‎HEPR)‎

Public health emergencies are occurring with increasing frequency and complexity, exposing weaknesses
in our current surveillance efforts for informing decision-making at all levels. Effective national surveillance is the foundation of global public health security, as all activities to prevent and mitigate

the impact of epidemics, pandemics, and other emergencies depend on our surveillance capabilities. The complex challenges highlighted by the COVID-19 pandemic and other emergencies emphasize the need to rethink our approach to surveillance while building upon the momentum of recent substantive investments in public health capacity.
