Adult mosquitoes were collected indoors and outdoors using battery\u2010powered aspirators, and immature stages were sampled from natural and artificial water containers. Mosquito pools were screened for DENV RNA using RT\u2010qPCR.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>A total of 6459 <jats:italic>Ae. aegypti<\/jats:italic> mosquitoes were sampled (54% females). DENV RNA was detected in 0.6% (4\/631) of the tested pools: one from Bahi and three from Kyela. No infections were detected in Ngorongoro. High mosquito density was observed in Kyela, particularly in paddy plantations and rice farms. Among DENV\u2010positive pools, 100% (4\/4) were collected near vegetation, suggesting that outdoor habitats are high\u2010risk sites. The minimum infection rate was 0.6 (95% CI: 0.2\u20131.6) per 1000 mosquitoes.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>This study confirms silent DENV circulation in <jats:italic>Ae. aegypti<\/jats:italic> populations in Tanzanian regions without prior epidemic reports. The detection of DENV in mosquitoes from Bahi and Kyela highlights the risk of future outbreaks and underscores the need for enhanced vector surveillance and integrated control strategies. These findings emphasise the urgency of preemptive public health measures to mitigate dengue spread in Tanzania. Limitations of the study include reliance on RT\u2010qPCR without viral isolation or serotyping and the absence of concurrent human clinical data.<\/jats:p><\/jats:sec>","DOI":"10.1111\/tmi.70032","type":"journal-article","created":{"date-parts":[[2025,9,2]],"date-time":"2025-09-02T09:09:25Z","timestamp":1756804165000},"page":"1134-1141","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Silent Circulation of Dengue Virus in <scp><i>Aedes aegypti<\/i><\/scp> Mosquitoes in Non\u2010Epidemic Regions of Tanzania: Implications for Surveillance and Control"],"prefix":"10.1111","volume":"30","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-7227-3564","authenticated-orcid":false,"given":"Clement N.","family":"Mweya","sequence":"first","affiliation":[{"name":"Mbeya College of Health and Allied Sciences University of Dar es Salaam  Mbeya Tanzania"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2025,9,2]]},"reference":[{"key":"e_1_2_9_2_1","doi-asserted-by":"publisher","DOI":"10.1186\/s13071-022-05401-9"},{"key":"e_1_2_9_3_1","doi-asserted-by":"publisher","DOI":"10.1371\/journal.pntd.0004313"},{"key":"e_1_2_9_4_1","doi-asserted-by":"publisher","DOI":"10.1093\/trstmh\/tru209"},{"key":"e_1_2_9_5_1","doi-asserted-by":"publisher","DOI":"10.1038\/nature12060"},{"key":"e_1_2_9_6_1","doi-asserted-by":"publisher","DOI":"10.1111\/nyas.13950"},{"key":"e_1_2_9_7_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jiph.2023.08.001"},{"key":"e_1_2_9_8_1","doi-asserted-by":"publisher","DOI":"10.1186\/s12967-024-05561-5"},{"key":"e_1_2_9_9_1","doi-asserted-by":"publisher","DOI":"10.3390\/v14020233"},{"key":"e_1_2_9_10_1","doi-asserted-by":"publisher","DOI":"10.4314\/thrb.v18i3.8"},{"key":"e_1_2_9_11_1","doi-asserted-by":"publisher","DOI":"10.1186\/s12879-024-10109-5"},{"key":"e_1_2_9_12_1","doi-asserted-by":"publisher","DOI":"10.4314\/tjs.v46i3.6"},{"key":"e_1_2_9_13_1","doi-asserted-by":"publisher","DOI":"10.1371\/journal.pntd.0006931"},{"key":"e_1_2_9_14_1","doi-asserted-by":"publisher","DOI":"10.1371\/journal.pone.0162649"},{"key":"e_1_2_9_15_1","doi-asserted-by":"publisher","DOI":"10.3390\/tropicalmed8090439"},{"key":"e_1_2_9_16_1","doi-asserted-by":"publisher","DOI":"10.1371\/journal.pntd.0007137"},{"key":"e_1_2_9_17_1","doi-asserted-by":"publisher","DOI":"10.1093\/jme\/tjac048"},{"key":"e_1_2_9_18_1","doi-asserted-by":"publisher","DOI":"10.1371\/journal.pone.0234675"},{"key":"e_1_2_9_19_1","doi-asserted-by":"publisher","DOI":"10.4269\/ajtmh.18-0798"},{"key":"e_1_2_9_20_1","doi-asserted-by":"publisher","DOI":"10.1093\/trstmh\/trac076"},{"key":"e_1_2_9_21_1","doi-asserted-by":"publisher","DOI":"10.11646\/zootaxa.700.1.1"},{"key":"e_1_2_9_22_1","doi-asserted-by":"publisher","DOI":"10.1603\/0022-2585-40.5.595"},{"key":"e_1_2_9_23_1","doi-asserted-by":"publisher","DOI":"10.1371\/journal.pntd.0010770"},{"key":"e_1_2_9_24_1","doi-asserted-by":"publisher","DOI":"10.1371\/journal.pone.0230337"},{"key":"e_1_2_9_25_1","doi-asserted-by":"publisher","DOI":"10.1128\/JCM.02153-16"},{"key":"e_1_2_9_26_1","doi-asserted-by":"publisher","DOI":"10.1371\/journal.pmed.0050205"},{"key":"e_1_2_9_27_1","doi-asserted-by":"publisher","DOI":"10.1371\/journal.pntd.0001730"}],"container-title":["Tropical Medicine &amp; International Health"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1111\/tmi.70032","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,10,7]],"date-time":"2025-10-07T07:05:18Z","timestamp":1759820718000},"score":1,"resource":{"primary":{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/10.1111\/tmi.70032"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2025,9,2]]},"references-count":26,"journal-issue":{"issue":"10","published-print":{"date-parts":[[2025,10]]}},"alternative-id":["10.1111\/tmi.70032"],"URL":"https:\/\/doi.org\/10.1111\/tmi.70032","archive":["Portico"],"relation":{},"ISSN":["1360-2276","1365-3156"],"issn-type":[{"type":"print","value":"1360-2276"},{"type":"electronic","value":"1365-3156"}],"subject":[],"published":{"date-parts":[[2025,9,2]]},"assertion":[{"value":"2025-06-13","order":0,"name":"received","label":"Received","group":{"name":"publication_history","label":"Publication History"}},{"value":"2025-08-27","order":2,"name":"accepted","label":"Accepted","group":{"name":"publication_history","label":"Publication History"}},{"value":"2025-09-02","order":3,"name":"published","label":"Published","group":{"name":"publication_history","label":"Publication History"}}]}}
