Comparison of virus detections reported as sentinel or non-sentinel by EU/EEA countries
- 1. Comparison of virus detections reported as sentinel or non-sentinel by EU/EAA countries Joint WHO/Europe & ECDC Annual Influenza Surveillance Meeting Vienna, 11-13 June 2014
- 2. Number of tested specimens Discrepancies between number of tested samples in sentinel/non-sentinel across countries: Different populations sampled in non-sentinel across countries? Comparability?
- 3. Non-sentinel data sources Countries General practices Paediatric practices Polyc linics ICU/ critical care General/ internal medicine Paediatric hospitals Maternity wards Infectious disease hospital wards Respiratory disease hospital wards Chronic disease hospital wards Specimens collected during respiratory disease outbreaks Other AT BE BG DK EE GR HU IS IT LV LT MT NO PL PT SK SE IE
- 4. Percentage of flu-positive specimens by surveillance system and week, 2010/11- 2013/14 Max. sentinel Max. non-sentinel Season threshold Discrepancies in sentinel/non-sentinel overall data for season estimate: How can non-sentinel data be used?
- 5. Number of flu- positive specimens by surveillance system, week and (sub)type, 2008/09- 2013/14
- 6. Summary Number of specimens tested vary between seasons and differ between countries -> different source populations of non-sentinel specimens? Positivity rate in non-sentinel differs to sentinel over weeks, lower amplitude and smaller number of week above 10% threshold – added value for season estimates? Distribution of types and subtypes differ between sentinel and non-sentinel specimens – how to interpret?
- 7. Points to be discussed Non-sentinel data are collected differently in every country (general practice and primary care, hospitals, ICU, outbreaks etc): 1. How should we pool the data at the Regional level? 2. What is the added value of the non-sentinel data and how can non- sentinel data be useful? 3. Which non-sentinel data should be reported from every country? 4. How should non-sentinel data be displayed, compared and reported in the joint bulletin?
