The survey, designed to assess the impact of the pandemic on the influenza surveillance system, was shared with 36 NICs located across 22 countries. NICs were invited to reply between November 2021 and March 2022.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>We received 18 responses from NICs in 14 countries. Most NICs (76%) indicated that the number of samples tested for influenza decreased. Yet, many NICs (60%) were able to increase their laboratory testing capacity and the \u201crobustness\u201d (e.g., number of sentinel sites) (59%) of their surveillance systems. In addition, sample sources (e.g., hospital or outpatient setting) shifted. All NICs reported a higher burden of work following the onset of the pandemic, with some NICs hiring additional staff or partial outsourcing to other institutes or departments. Many NICs anticipate the future integration of SARS\u2010CoV\u20102 surveillance into the existing respiratory surveillance system.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Discussion<\/jats:title>\n                    <jats:p>The survey shows the profound impact of SARS\u2010CoV\u20102 on national influenza surveillance in the first 27\u2009months of the pandemic. Surveillance activities were temporarily disrupted, whilst priority was given to SARS\u2010CoV\u20102. However, most NICs have shown rapid adaptive capacity underlining the importance of strong national influenza surveillance systems. These developments have the potential to benefit global respiratory surveillance in the years to come; however, questions about sustainability remain.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1111\/irv.13140","type":"journal-article","created":{"date-parts":[[2023,5,11]],"date-time":"2023-05-11T05:22:10Z","timestamp":1683782530000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":15,"title":["The impact of the SARS\u2010CoV\u20102 pandemic on global influenza surveillance: Insights from 18 National Influenza Centers based on a survey conducted between November 2021 and March 2022"],"prefix":"10.1111","volume":"17","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-6985-3541","authenticated-orcid":false,"given":"Lisa","family":"Staadegaard","sequence":"first","affiliation":[{"name":"Netherlands Institute for Health Services Research (Nivel)  Utrecht The Netherlands"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2742-0297","authenticated-orcid":false,"given":"Marco","family":"Del Riccio","sequence":"additional","affiliation":[{"name":"Netherlands Institute for Health Services Research (Nivel)  Utrecht The Netherlands"},{"name":"Postgraduate Medical School in Public Health University of Florence  Florence Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sytske","family":"Wiegersma","sequence":"additional","affiliation":[{"name":"Netherlands Institute for Health Services Research (Nivel)  Utrecht The Netherlands"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0196-4357","authenticated-orcid":false,"given":"Clotilde","family":"El Guerche\u2010S\u00e9blain","sequence":"additional","affiliation":[{"name":"Sanofi, Global Medical Influenza Franchise  Lyon France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Erica","family":"Dueger","sequence":"additional","affiliation":[{"name":"Sanofi, Global Medical Influenza Franchise  Lyon France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Meral","family":"Ak\u00e7ay","sequence":"additional","affiliation":[{"name":"Sanofi, Global Medical Influenza Franchise  Lyon France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3271-9856","authenticated-orcid":false,"given":"Jean\u2010Sebastien","family":"Casalegno","sequence":"additional","affiliation":[{"name":"Netherlands Institute for Health Services Research (Nivel)  Utrecht The Netherlands"},{"name":"Hospices Civils de Lyon, H\u00f4pital de la Croix\u2010Rousse, Centre de Biologie Nord, Institut des Agents Infectieux, Laboratoire de Virologie  Lyon France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7746-053X","authenticated-orcid":false,"given":"Michel","family":"D\u00fcckers","sequence":"additional","affiliation":[{"name":"Netherlands Institute for Health Services Research (Nivel)  Utrecht The Netherlands"},{"name":"ARQ National Psychotrauma Centre  Diemen The Netherlands"},{"name":"Faculty of Behavioural and Social Sciences University of Groningen  Groningen The Netherlands"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2262-1102","authenticated-orcid":false,"given":"Saverio","family":"Caini","sequence":"additional","affiliation":[{"name":"Netherlands Institute for Health Services Research (Nivel)  Utrecht The Netherlands"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1503-2481","authenticated-orcid":false,"given":"John","family":"Paget","sequence":"additional","affiliation":[{"name":"Netherlands Institute for Health Services Research (Nivel)  Utrecht The Netherlands"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"name":"The NIC Collaborators","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2023,5,11]]},"reference":[{"key":"e_1_2_10_2_1","doi-asserted-by":"publisher","DOI":"10.2807\/1560\u20107917.ES.2021.26.40.2100077"},{"key":"e_1_2_10_3_1","doi-asserted-by":"publisher","DOI":"10.1016\/S2213\u20102600(18)30496\u2010X"},{"key":"e_1_2_10_4_1","unstructured":"Influenza (Seasonal).https:\/\/www.who.int\/news-room\/fact-sheets\/detail\/influenza-(seasonal).
