Consequently, the development and implementation of feasible, cost-effective, and sustainable surveillance strategies are essential. Molecular xenosurveillance (MX) represents an innovative approach for arbovirus monitoring, including dengue surveillance, which utilizes field-collected mosquito specimens to detect circulating pathogens and provide early outbreak warnings. Bangladesh is highly endemic for dengue, and with limited resources, the implementation of MX will add value to ongoing efforts to scale up surveillance. This study aimed to test the suitability of MX in detecting dengue viruses in\n                      <jats:italic toggle=\"yes\">Aedes<\/jats:italic>\n                      vectors and recommend its integration into the existing surveillance system.

The DENV-2 serotype was detected in the positive pool.

These findings provide empirical support for enhanced vector surveillance protocols and offer valuable insights for strengthening comprehensive dengue control efforts.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>IMPORTANCE<\/jats:title>\n                    <jats:p>\n                      The timely detection of arboviral pathogens like dengue virus, through surveillance is critical for developing early warning systems and preventing outbreaks. However, limited surveillance capacity in resource-constrained settings creates gaps that can be addressed by implementing sustainable and cost-effective surveillance strategies. This study demonstrates the feasibility of molecular xenosurveillance (MX), which is a vector-based, non-invasive surveillance method for dengue virus surveillance in\n                      <jats:italic toggle=\"yes\">Aedes aegypti<\/jats:italic>\n                      mosquitoes in Dhaka, Bangladesh. By detecting and identifying dengue virus serotype-2 (DENV-2) using real-time RT-PCR, this study also provides evidence of the method's potential for generating deeper epidemiological insights. These findings highlight the value of MX as a complementary tool to existing surveillance systems. Integrating MX into routine entomological surveillance could significantly enhance national preparedness and response to dengue outbreaks.\n                    <\/jats:p>\n                  <\/jats:sec>","DOI":"10.1128\/spectrum.01769-25","type":"journal-article","created":{"date-parts":[[2025,9,26]],"date-time":"2025-09-26T13:00:08Z","timestamp":1758891608000},"update-policy":"https:\/\/doi.org\/10.1128\/asmj-crossmark-policy-page","source":"Crossref","is-referenced-by-count":1,"title":["Molecular xenosurveillance of\n                    <i>Aedes<\/i>\n                    mosquitoes reveals dengue virus serotype-2 during an outbreak in Dhaka, Bangladesh"],"prefix":"10.1128","volume":"13","author":[{"given":"Prakash","family":"Ghosh","sequence":"first","affiliation":[{"id":[{"id":"https:\/\/ror.org\/04vsvr128","id-type":"ROR","asserted-by":"publisher"}],"name":"Maternal and Child Nutrition, Nutrition Research Division, icddr,b","place":["Dhaka, Bangladesh"]},{"id":[{"id":"https:\/\/ror.org\/03s7gtk40","id-type":"ROR","asserted-by":"publisher"}],"name":"Institute for Animal Hygiene and Veterinary Public Health, Leipzig University","place":["Leipzig, Germany"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Anupama","family":"Hazarika","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/01yb6xh37","id-type":"ROR","asserted-by":"publisher"}],"name":"Communicable Disease Surveillance (CDS), World Health Organization Bangladesh","place":["Dhaka, Bangladesh"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Md.
