10 SURVEILLANCE
Surveillance is defined under the IHR as the systematic ongoing collection, collation and analysis of data for public health purposes and the timely dissemination of public health information for action. Annex 1 of the IHR outlines core capacities required for surveillance at local/primary, subnational and national public health response levels, including detection, reporting, notification, verification and collaboration activities.
To address the challenges highlighted by the COVID-19 pandemic and other past and current emergencies, the collaborative surveillance concept has been introduced as a core building block of the WHO Framework for Strengthening Global Architecture for Health Emergency Preparedness, Response, and Resilience (HEPR), which proposes key objectives and capabilities for strengthening public health intelligence for improved decision-making. Collaborative surveillance is defined as “the systematic strengthening of capacity and collaboration among diverse stakeholders, both within and beyond the health sector, with the ultimate goal of enhancing public health intelligence and improving evidence for decision making”. This concept promotes the strengthening of routine surveillance capacities (including public health and laboratory surveillance) and health systems monitoring, and collaboration between and beyond these systems to collectively support diverse surveillance objectives and decision-maker needs on a routine ongoing basis and toward health emergency prevention, preparedness, response and recovery.
Benchmark actions listed below are limited to areas related defined by the current JEE indicators (3rd edition):
- D2.1. Earlier warning surveillance function
- D2.2. Event verification and investigation; and
- D2.3. Analysis and information sharing.
Wherever possible, countries should consider the full range of collaborative surveillance objectives, capacities, and subcapabilities in addition to those outlined here, as well as other related benchmarks, during the prioritization of actions.
IMPACT:
