This study aimed to develop machine learning models that leverage readily available clinical data to improve diagnostic accuracy for dengue, potentially offering a more accessible and rapid diagnostic tool for healthcare providers.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>We used data from the Sentinel Enhanced Dengue Surveillance System in Puerto Rico (May 2012\u2013June 2024). The Sentinel Enhanced Dengue Surveillance System primarily targets acute febrile illness but also includes cases with other symptoms during outbreaks (e.g., Zika and COVID\u201019). Machine learning models (logistic regression, random forest, support vector machine, artificial neural network, adaptive boosting, light gradient boosting machine [LightGBM] and extreme gradient boosting [XGBoost]) were evaluated across different feature sets, including demographic, clinical, laboratory and epidemiological variables. Model performance was assessed using the area under the receiver operating characteristic curve (AUC), where higher AUC values indicate better performance in distinguishing dengue cases from non\u2010dengue cases.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Among 49,679 patients in SEDSS, 1640 laboratory\u2010confirmed dengue cases were identified. The XGBoost and LightGBM models achieved the highest diagnostic accuracy, with AUCs exceeding 90%, particularly with comprehensive feature sets. Incorporating predictors such as monthly dengue incidence, leukopenia, thrombocytopenia, rash, age and absence of nasal discharge significantly enhanced model sensitivity and specificity for diagnosing dengue. Adding more relevant clinical and epidemiological features consistently improved the models' ability to correctly identify dengue cases.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Machine learning models, especially XGBoost and LightGBM, show promise for improving diagnostic accuracy for dengue using widely accessible clinical data, even in resource\u2010limited settings. Future research should focus on developing user\u2010friendly tools, such as mobile apps, web\u2010based platforms, or clinical decision systems integrated into electronic health records, to implement these models in clinical practice and exploring their application for predicting dengue.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1111\/tmi.70036","type":"journal-article","created":{"date-parts":[[2025,9,16]],"date-time":"2025-09-16T05:49:27Z","timestamp":1758001767000},"page":"1283-1294","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Machine Learning for Improved Dengue Diagnosis in Puerto Rico"],"prefix":"10.1111","volume":"30","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-5667-9660","authenticated-orcid":false,"given":"Zachary J.","family":"Madewell","sequence":"first","affiliation":[{"name":"Division of Vector\u2010Borne Diseases Centers for Disease Control and Prevention  San Juan Puerto Rico"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2837-3629","authenticated-orcid":false,"given":"Dania M.","family":"Rodriguez","sequence":"additional","affiliation":[{"name":"Division of Vector\u2010Borne Diseases Centers for Disease Control and Prevention  San Juan Puerto Rico"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6952-0440","authenticated-orcid":false,"given":"Maile B.","family":"Thayer","sequence":"additional","affiliation":[{"name":"Division of Vector\u2010Borne Diseases Centers for Disease Control and Prevention  San Juan Puerto Rico"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0289-3135","authenticated-orcid":false,"given":"Vanessa","family":"Rivera\u2010Amill","sequence":"additional","affiliation":[{"name":"Ponce Health Sciences University Ponce Research Institute  Ponce Puerto Rico"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jomil Torres","family":"Aponte","sequence":"additional","affiliation":[{"name":"Division of Vector\u2010Borne Diseases Centers for Disease Control and Prevention  San Juan Puerto Rico"},{"name":"Division of Epidemiology &amp; Research Puerto Rico Department of Health  San Juan Puerto Rico"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Melissa","family":"Marzan\u2010Rodriguez","sequence":"additional","affiliation":[{"name":"Division of Epidemiology &amp; Research Puerto Rico Department of Health  San Juan Puerto Rico"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8478-4911","authenticated-orcid":false,"given":"Gabriela","family":"Paz\u2010Bailey","sequence":"additional","affiliation":[{"name":"Division of Vector\u2010Borne Diseases Centers for Disease Control and Prevention  San Juan Puerto Rico"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Laura E.","family":"Adams","sequence":"additional","affiliation":[{"name":"Division of Vector\u2010Borne Diseases Centers for Disease Control and Prevention  San Juan Puerto Rico"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1062-0049","authenticated-orcid":false,"given":"Joshua M.","family":"Wong","sequence":"additional","affiliation":[{"name":"Division of Vector\u2010Borne Diseases Centers for Disease Control and Prevention  San Juan Puerto Rico"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2025,9,15]]},"reference":[{"key":"e_1_2_8_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0140-6736(23)02576-X"},{"key":"e_1_2_8_3_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0188-4409(02)00378-8"},{"key":"e_1_2_8_4_1","doi-asserted-by":"publisher","DOI":"10.14423\/SMJ.0000000000001152"},{"key":"e_1_2_8_5_1","doi-asserted-by":"publisher","DOI":"10.1056\/NEJMra1110265"},{"key":"e_1_2_8_6_1","doi-asserted-by":"publisher","DOI":"10.1111\/tmi.12498"},{"key":"e_1_2_8_7_1","doi-asserted-by":"publisher","DOI":"10.1371\/journal.pntd.0002056"},{"key":"e_1_2_8_8_1","doi-asserted-by":"publisher","DOI":"10.1038\/nature12060"},{"key":"e_1_2_8_9_1","doi-asserted-by":"publisher","DOI":"10.3201\/eid2508.190089"},{"key":"e_1_2_8_10_1","doi-asserted-by":"publisher","DOI":"10.3390\/ijerph110909409"},{"key":"e_1_2_8_11_1","doi-asserted-by":"publisher","DOI":"10.15585\/mmwr.ss7204a1"},{"key":"e_1_2_8_12_1","article-title":"Dengue Epidemic Alert Thresholds: A Tool for Surveillance and Epidemic Detection","author":"Thayer M.
