Abstract Mexico has experienced recurrent viral epidemics of substantial intensity, including hyperendemic dengue, COVID-19, and recent reports of avian influenza A (H5N1) infections in birds , which pose an ongoing risk of zoonotic transmission . Mexico was also the location for the earliest detection of the pdmH1N1 virus during the 2009 influenza A pandemic. Under a One Health framework , markets represent a unique opportunity for low-cost virus monitoring at the human-animal interface . Under the hypothesis that these represent sentinel sites for an early virus detection , we implemented a pilot surveillance program at the central market of Merida city, Yucatan , Mexico, considered a regional hotspot for multiple and recent viral outbreaks . Longitudinal sampling was carried out over 11 months at 1-to-6-week intervals from April 2022 to February 2023 . We used multi-type surveillance in mosquitoes, live poultry, and wastewater . All samples were screened using RT-qPCR . Positi...
