Colombia has experienced intense dengue activity in recent years; however, integrated analyses combining virological, spatial, and clinical data remain limited.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec id=\"sec002\">\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>A retrospective longitudinal observational study was conducted using routinely collected dengue surveillance data from the Department of Meta, Colombia, covering the period from January 2023 to September 2025. Confirmed dengue cases with viral isolation and serotype identification were included. Temporal trends, serotype replacement dynamics, municipal-level spatial redistribution patterns, and clinical characteristics were analyzed using laboratory-confirmed dengue cases. Multivariable logistic regression models were used to identify factors associated with dengue positivity overall and by serotype, while interannual variation was assessed to evaluate changes in transmission intensity and the spatial redistribution of dengue transmission risk.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec id=\"sec003\">\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Marked serotype replacement was observed during the study period. DENV-2 predominated during the 2023 peak, followed by a decline and a sustained increase in DENV-3 and DENV-4 by 2025, while DENV-1 disappeared from recent records. Spatial analysis showed declining diagnostic positivity in historically hyperendemic municipalities and significant interannual increases in intermediate municipalities, indicating an epidemiological rebound outside major urban centers. Classical dengue symptoms, including headache, myalgia, and rash, were inversely associated with virological confirmation, whereas nonspecific neurological manifestations, such as somnolence and irritability, emerged as independent predictors. Severe thrombocytopenia remained strongly associated with infection, particularly in DENV-2 cases.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec id=\"sec004\">\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>The dengue outbreak in Meta (2023\u20132025) was characterized by dynamic serotype replacement, spatial redistribution of transmission risk, and changing clinical presentations. The rapid emergence of DENV-4 in 2025 serves as an early warning of serotype replacement and underscores the need to update clinical screening protocols to include nonspecific neurological manifestations. Strengthening decentralized laboratory networks and closing surveillance gaps in low-endemicity areas are strategic priorities to improve early detection and outbreak control in hyperendemic regions.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1371\/journal.pntd.0014733","type":"journal-article","created":{"date-parts":[[2026,9,25]],"date-time":"2026-09-25T17:39:27Z","timestamp":1790357967000},"page":"e0014733","update-policy":"https:\/\/doi.org\/10.1371\/journal.pntd.corrections_policy","source":"Crossref","is-referenced-by-count":0,"title":["Early warning of serotype replacement, spatial risk redistribution, and shifting clinical phenotypes: Insights from the 2023\u20132025 dengue outbreak in Meta, Colombia"],"prefix":"10.1371","volume":"20","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-0917-4288","authenticated-orcid":true,"given":"Liliana Marcela","family":"Montilla Rodr\u00edguez","sequence":"first","affiliation":[{"name":"Universidad Cooperativa de Colombia","place":["Villavicencio, Colombia"],"department":["Faculty of Medicine"]},{"name":"GRIVI","place":["Villavicencio, Colombia"]},{"name":"GISSME, Secretar\u00eda de Salud del Meta","place":["Villavicencio, Colombia"],"department":["Laboratorio de Salud P\u00fablica"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Cesar","family":"Garc\u00eda-Balaguera","sequence":"additional","affiliation":[{"name":"Universidad Cooperativa de Colombia","place":["Villavicencio, Colombia"],"department":["Faculty of Medicine"]},{"name":"GRIVI","place":["Villavicencio, Colombia"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sandra","family":"Campo Palacio","sequence":"additional","affiliation":[{"name":"GISSME, Secretar\u00eda de Salud del Meta","place":["Villavicencio, Colombia"],"department":["Laboratorio de Salud P\u00fablica"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"David","family":"Bonilla Montes","sequence":"additional","affiliation":[{"name":"Universidad Cooperativa de Colombia","place":["Villavicencio, Colombia"],"department":["Faculty of Medicine"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yuri Daniela","family":"Cadena D\u00edaz","sequence":"additional","affiliation":[{"name":"Universidad Cooperativa de Colombia","place":["Villavicencio, Colombia"],"department":["Faculty of Medicine"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Paula Alejandra","family":"Mosquera Tocora","sequence":"additional","affiliation":[{"name":"Universidad Cooperativa de Colombia","place":["Villavicencio, Colombia"],"department":["Faculty of Medicine"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Norma Cristina","family":"Pavas Escobar","sequence":"additional","affiliation":[{"name":"Universidad Cooperativa de Colombia","place":["Villavicencio, Colombia"],"department":["Faculty of Medicine"]},{"name":"GRIVI","place":["Villavicencio, Colombia"]},{"name":"GISSME, Secretar\u00eda de Salud del Meta","place":["Villavicencio, Colombia"],"department":["Laboratorio de Salud P\u00fablica"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Camilo","family":"Andrade Carre\u00f1o","sequence":"additional","affiliation":[{"name":"GISSME, Secretar\u00eda de Salud del Meta","place":["Villavicencio, Colombia"],"department":["Laboratorio de Salud P\u00fablica"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Elsa Victoria","family":"Andrade Miranda","sequence":"additional","affiliation":[{"name":"GISSME, Secretar\u00eda de Salud del Meta","place":["Villavicencio, Colombia"],"department":["Laboratorio de Salud P\u00fablica"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marina Sthella","family":"Gonzalez Robayo","sequence":"additional","affiliation":[{"name":"GISSME, Secretar\u00eda de Salud del Meta","place":["Villavicencio, Colombia"],"department":["Laboratorio de Salud P\u00fablica"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"340","published-online":{"date-parts":[[2026,9,25]]},"reference":[{"key":"pntd.0014733.ref001","unstructured":"World Health Organization.
