Leveraging global expertise and experiences to develop the mosaic
framework
The mosaic surveillance framework was developed by drawing on the
experiences of a technical working group (TWG) that included WHO subject
matter experts from more than 20 teams / departments at WHO
headquarters, and members from WHO regional offices (RO) in all six WHO
regions. To further obtain experiences and perspectives from countries
of all socio-economic levels, a secretariat supported WHO Regional
Offices as they worked with Country Offices and Ministry of Health
partners to implement surveys and gather data on priority objectives,
surveillance systems currently used to meet those objectives, and
priority surveillance enhancements needed. The Regional Offices also
convened regional consultations and focused discussions with countries,
informed by surveys, to obtain input for the global consultation. WHO
headquarters then hosted a global consultation entitled “’Crafting the
Mosaic’: Resilient surveillance systems for respiratory viruses of
pandemic potential” on 10 & 11 May 2022. This consultation included
340 in-person and on-line attendees including those working in
surveillance at the country level, and representatives from WHO Country
Offices, all six Regional Offices, WHO headquarters, and external
partner organizations. The framework incorporated iterative feedback
from the TWG, the WHO COVID-19 incident management team leadership, and
external subject matter experts from the United States Centers for
Disease Control and Prevention, The European Centre for Disease
Prevention and Control, The Global Fund, The Bill and Melinda Gates
Foundation, and The Rockefeller Foundation. The secretariat also
collected case studies by working with WHO Regional Offices to obtain
examples of implementation of different surveillance systems and studies
to meet priority objectives. These case studies provide national
authorities with examples of the use of different systems to help them
move from a theoretical to practical level.
