WHO global manual on surveillance of human influenza

1. WHO global manual on surveillance of human influenza July 7th 2010 Siri Helene Hauge, Global Influenza Programme

2. Global Manual on Influenza Surveillance • Method • Using already existing guidelines as framework • Draft by WHO HQ/GIP • Feedback from stakeholders • Manual will give a minimum standard

3. Process and timeline • Evaluated by the WHO Guideline Review Committee in May 2010 • First draft to be circulated July 2010 • WHO Regional Offices • GlP WHO HQ • Epi-network • Second draft autumn 2010 • To be discussed on November 2010 meeting • Final draft end of 2010 • Printing March 2010

4. Global manual – why? • No global or inter-regional recommendations/guidelines exist • Regional guidelines/drafts exists but vary in how elaborate they are • The pandemic highlighted the need for standardized epidemiological data • Help for revisions and production of regional and national surveillance guidelines

5. Global manual – to provide: • A common platform for information on how to systematically collect and to analyze data on influenza • A basic framework for future revisions/making of guidelines on influenza surveillance • An essential framework adaptable by countries including those with limited resources for influenza surveillance • A framework for a common system to ensure seasonal and pandemic surveillance

6. Global manual – for whom • Assistance to • National surveillance teams • Policy makers • Health workers • WHO Regional offices

7. Some existing guidelines/recommendations • Human infection with pandemic (H1N1) 2009 virus: updated interim WHO guidance on global surveillance • WHO manual for the laboratory diagnosis and virological surveillance of influenza Human infection with pandemic (H1N1) 2009 virus: updated interim WHO guidance on global surveillance • WHO European guidance for influenza surveillance in humans • WPRO: A practical guide to harmonizing virological and epidemiological influenza surveillance • AFRO: Protocol for National Influenza Sentinel Surveillance • EMRO: Sentinel surveillance of pandemic (H1N1) 2009 • SEARO: A Practical guide for operationalizing WHO influenza surveillance guidance • PAHO-CDC generic protocol for influenza surveillance

8. Content Standard case definitions: ILI and SARI for adults and children Sentinel site characteristics (minimum standard) and criteria for selection Data collection tools – minimum data set, data reports Use (and additional use) of data and possible action (baseline/thresholds)/ minimal data analysis/indicators recommended Laboratory specimen collection, storage, transport (WHO manual) Testing procedures/selection of patients to test Recommended reporting and feed-back mechanisms (FluID)

9. Outline Introduction Objectives of sentinel surveillance of ILI, SARI and ARI Case definitions Sentinel sites characteristics Laboratory surveillance Data collection Data reporting Data analysis Quality of data Pandemic detection Roles and responsibilities Legal issues

10. Discussion points • SARI vs. ILI surveillance • Case definition ILI (EU to change?) • Sentinel site selection • Indicators • Baseline • Others?
