The cohort included individuals aged \u2a7e25\u2009years from 2005 to 2022, with follow-up through 2023. New stroke cases were matched with controls based on age, sex, population sector, and index date. HZ exposure was defined by International Classification of Diseases, Ninth Revision (ICD)-9 codes within 90\u2009days prior to the index date, with concomitant acyclovir or valacyclovir treatment. Additional analyses explored longer time windows for HZ infection exposure, specifically within 1 and 5\u2009years prior to the index date.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>A total of 66,818 stroke cases were matched with 66,818 controls. HZ infection within the prior 90\u2009days was associated with a significantly increased overall stroke odds, with adjusted odds ratio (OR) = 1.63 (95% confidence interval (CI) = 1.26\u20132.10). The strength of the association weakened and did not reach statistical significance with longer prior HZ exposure windows; adjusted OR = 1.12 (0.99\u20131.27) within 1\u2009year and 1.07 (1.00\u20131.14) within 5\u2009years. The pattern was similar for ischemic stroke and ICH, with a significant association observed only for HZ infection within the prior 90\u2009days with adjusted ORs 1.54 (1.18\u20132.02) and 2.73 (1.16\u20136.42), respectively.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions:<\/jats:title>\n                    <jats:p>HZ infection is associated with increased stroke risk within 90\u2009days post-infection and appears to be a stronger risk factor for ICH.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1177\/17474930251338202","type":"journal-article","created":{"date-parts":[[2025,4,17]],"date-time":"2025-04-17T00:42:18Z","timestamp":1744850538000},"page":"1081-1089","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":5,"title":["Association between herpes zoster infection and the risk of stroke: A population-based nested case\u2013control study"],"prefix":"10.1177","volume":"20","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8686-2431","authenticated-orcid":false,"given":"Amir","family":"Yahav","sequence":"first","affiliation":[{"name":"Department of Community Medicine and Epidemiology, The Lady Davis Carmel Medical Center, Haifa, Israel"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jonathan","family":"Naftali","sequence":"additional","affiliation":[{"name":"Department of Neurology, Rabin Medical Center, Petach Tikva, Israel"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Doaa","family":"Ryan","sequence":"additional","affiliation":[{"name":"Department of Community Medicine and Epidemiology, The Lady Davis Carmel Medical Center, Haifa, Israel"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Anat","family":"Arbel","sequence":"additional","affiliation":[{"name":"Infection Control and Prevention Unit, The Lady Davis Carmel Medical Center, Haifa, Israel"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ronza","family":"Najjar-Debbiny","sequence":"additional","affiliation":[{"name":"Infection Control and Prevention Unit, The Lady Davis Carmel Medical Center, Haifa, Israel"},{"name":"The Ruth and Bruce Rappaport Faculty of Medicine, Technion Israel Institute of Technology, Haifa, Israel"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nili","family":"Stein","sequence":"additional","affiliation":[{"name":"Department of Community Medicine and Epidemiology, The Lady Davis Carmel Medical Center, Haifa, Israel"},{"name":"Statistical Unit, The Lady Davis Carmel Medical Center, Haifa, Israel"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ofra","family":"Barnett-Griness","sequence":"additional","affiliation":[{"name":"Department of Community Medicine and Epidemiology, The Lady Davis Carmel Medical Center, Haifa, Israel"},{"name":"Statistical Unit, The Lady Davis Carmel Medical Center, Haifa, Israel"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Walid","family":"Saliba","sequence":"additional","affiliation":[{"name":"Department of Community Medicine and Epidemiology, The Lady Davis Carmel Medical Center, Haifa, Israel"},{"name":"The Ruth and Bruce Rappaport Faculty of Medicine, Technion Israel Institute of Technology, Haifa, Israel"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Eitan","family":"Auriel","sequence":"additional","affiliation":[{"name":"Department of Neurology, Rabin Medical Center, Petach Tikva, Israel"},{"name":"School of Medicine, Tel Aviv University, Tel Aviv, Israel"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2025,5,10]]},"reference":[{"key":"e_1_3_2_2_2","doi-asserted-by":"publisher","DOI":"10.1111\/ene.14988"},{"key":"e_1_3_2_3_2","first-page":"447","article-title":"Extended risk factors for stroke prevention","volume":"111","author":"Zhang S","year":"2019","unstructured":"Zhang S, Zhang W, Zhou G.
