There is limited and outdated information on the circulation of EIAV in many European countries. In the present study, we aimed to assess virus exposure in different equid species in Western Europe. Methods: Between 2011 and 2023, a cross-sectional study was conducted to investigate the seroprevalence of EIAV in 1676 equids (1444 horses, 106 donkeys and 126 mules\/hinnies) from four European regions: Andalusia (Southern Spain; n = 808), Catalonia (Northeastern Spain; n = 437), Southeastern United Kingdom (UK; n = 209), and Ireland (n = 222). Results: None of the analyzed equines tested positive for antibodies against EIAV (0%; 95\u2009%CI: 0.0\u20130.18), indicating limited virus exposure of the equid populations from these European regions. Conclusions: This finding is consistent with the low EIAV circulation previously reported in Western Europe and the few official EIA outbreaks recorded in the region during the last decade. To the best of the author\u2019s knowledge, this serosurvey represents the first investigation assessing EIAV exposure in equids from Ireland and the UK. Our results not only provide novel epidemiological evidence for the four European regions assessed but also reinforce the effectiveness of surveillance strategies and control measures implemented by European countries, in accordance with national and international regulations, to successfully limit EIAV circulation.<\/jats:p>","DOI":"10.3390\/ani15233499","type":"journal-article","created":{"date-parts":[[2025,12,4]],"date-time":"2025-12-04T15:14:06Z","timestamp":1764861246000},"page":"3499","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Equine Infectious Anemia Virus in Equids: A Large-Scale Serosurvey in Western Europe"],"prefix":"10.3390","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-0423-3189","authenticated-orcid":false,"given":"Mois\u00e9s","family":"Gonz\u00e1lvez","sequence":"first","affiliation":[{"name":"Departamento de Sanidad Animal, Grupo de Investigaci\u00f3n en Sanidad Animal y Zoonosis (GISAZ), UIC Zoonosis y Enfermedades Emergentes ENZOEM, Universidad de C\u00f3rdoba, 14014 C\u00f3rdoba, Spain"},{"name":"Grupo Sanidad y Biotecnolog\u00eda (SaBio), Instituto de Investigaci\u00f3n en Recursos Cineg\u00e9ticos (IREC), CSIC-UCLM-JCCM, 13005 Ciudad Real, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Juan J.","family":"Franco","sequence":"additional","affiliation":[{"name":"Gold Standard Diagnostics Madrid, 28037 Madrid, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5657-2567","authenticated-orcid":false,"given":"David","family":"Cano-Terriza","sequence":"additional","affiliation":[{"name":"Departamento de Sanidad Animal, Grupo de Investigaci\u00f3n en Sanidad Animal y Zoonosis (GISAZ), UIC Zoonosis y Enfermedades Emergentes ENZOEM, Universidad de C\u00f3rdoba, 14014 C\u00f3rdoba, Spain"},{"name":"CIBERINFEC, ISCIII CIBER de Enfermedades Infecciosas, Instituto de Salud Carlos III, 28029 Madrid, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3440-1315","authenticated-orcid":false,"given":"Jes\u00fas","family":"Barbero-Moyano","sequence":"additional","affiliation":[{"name":"Departamento de Sanidad Animal, Grupo de Investigaci\u00f3n en Sanidad Animal y Zoonosis (GISAZ), UIC Zoonosis y Enfermedades Emergentes ENZOEM, Universidad de C\u00f3rdoba, 14014 C\u00f3rdoba, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4536-7717","authenticated-orcid":false,"given":"Eduard","family":"Jose-Cunilleras","sequence":"additional","affiliation":[{"name":"Servei de Medicina Interna Equina, Departament de Medicina i Cirurgia Animals, Facultat de Veterin\u00e0ria, Universitat Aut\u00f2noma de Barcelona, 08193 Barcelona, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jes\u00fas","family":"Garc\u00eda","sequence":"additional","affiliation":[{"name":"Fethard Equine Hospital, E91 Y6T8 Tipperary, Ireland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Eduardo","family":"Alguacil","sequence":"additional","affiliation":[{"name":"Uplands Way Vets, Diss IP22 2AA, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3388-2604","authenticated-orcid":false,"given":"Ignacio","family":"Garc\u00eda-Bocanegra","sequence":"additional","affiliation":[{"name":"Departamento de Sanidad Animal, Grupo de Investigaci\u00f3n en Sanidad Animal y Zoonosis (GISAZ), UIC Zoonosis y Enfermedades Emergentes ENZOEM, Universidad de C\u00f3rdoba, 14014 C\u00f3rdoba, Spain"},{"name":"CIBERINFEC, ISCIII CIBER de Enfermedades Infecciosas, Instituto de Salud Carlos III, 28029 Madrid, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,12,4]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"181","DOI":"10.1016\/j.vetmic.2013.09.031","article-title":"Equine Infectious Anemia and Equine Infectious Anemia Virus in 2013: A review","volume":"167","author":"Cook","year":"2013","journal-title":"Vet.
