UF-led $3.5 million grant expands arbovirus surveillance: full analysis

A University of Florida-led team has secured a $3.5 million NIH award to expand arbovirus surveillance using a One Health framework aimed at catching mosquito-borne threats before they spread more widely. University of Florida reporting on the grant highlighted the preventive logic plainly: build surveillance capacity abroad before emerging pathogens “come home.” Supporting documents tied to principal investigator Rhoel Dinglasan identify the project as VirCapSeq-ONT, a five-year award running from April 24, 2024, to March 31, 2029, with Dinglasan, Christian Happi, and Charles Wondji leading the work.

The award fits squarely into Dinglasan’s broader research portfolio at UF, which spans malaria transmission biology, vector-borne disease surveillance, and translational tools for earlier detection. UF has also been deeply involved in vector-borne disease infrastructure for years, including the CDC’s Centers of Excellence in Vector-Borne Diseases and prior Zika-era collaborations that linked university researchers with mosquito control programs across Florida. That history matters because this new grant doesn’t appear to be a stand-alone project; it builds on an existing institutional push to connect entomology, pathogen detection, field surveillance, and public health response.

The technical centerpiece is xenosurveillance, which uses blood-feeding arthropods such as mosquitoes as sampling tools to detect pathogens circulating in humans or animals. In Dinglasan’s CV, the project goal is described as using VirCapSeq-ONT “for assessing, detecting, and preventing in-country and transborder transmission of arboviruses” and using arthropod xenosurveillance to measure arbovirus distribution and movement at interior transboundary sites. That suggests the grant is focused not just on identifying viruses, but on building a surveillance system that can map movement across borders and potentially flag spillover or expansion events earlier than conventional clinical case finding.

That approach arrives as arbovirus surveillance is getting renewed attention across both human and animal health. Florida’s Department of Health maintains dedicated arbovirus surveillance guidance for mosquito-borne diseases of public health importance, and recent scientific literature has argued for stronger, more proactive surveillance rather than reactive policy cycles. A 2022 paper co-authored by Dinglasan warned that U.S. vector-borne disease policy has often been cyclical and outbreak-driven, leaving the country vulnerable between emergencies. More recent veterinary diagnostic commentary has also emphasized the value of sentinel and longitudinal animal surveillance for mosquito-borne infections. (floridahealth.gov)

Industry reaction specific to this grant was limited in public sources, but the broader expert signal is consistent: surveillance capacity is increasingly being treated as frontline prevention. That’s also visible in parallel UF work on emerging vector-borne threats, including public-facing expert commentary on Oropouche virus and other pathogens that may spread into new regions. The through line is that earlier detection, better diagnostics, and stronger cross-border intelligence are becoming central to outbreak prevention, not secondary to it. (news.ufl.edu)

Why it matters: For veterinary professionals, the grant is notable less for the dollar figure than for what it reinforces about where infectious disease preparedness is heading. Arboviruses don’t respect the boundaries between companion animal, livestock, wildlife, and human health. Veterinarians are often among the first to see unusual neurologic, febrile, reproductive, or herd-level patterns that can signal vector-borne disease activity, especially in equine and food animal settings. Investments in surveillance platforms that can detect pathogen circulation earlier may eventually improve case recognition, inform regional risk communication, and support more targeted mosquito control and diagnostic decision-making.

The One Health angle is especially relevant. Florida’s surveillance systems already reflect the need to integrate animal, vector, and human data, and this grant appears to extend that model internationally and across borders. If the platform can produce timely, field-ready data, it could help veterinary and public health partners move from reacting to outbreaks toward anticipating them. That would be meaningful in a landscape where climate shifts, travel, trade, and vector expansion are increasing the odds that unfamiliar arboviruses show up in new places. (floridahealth.gov)

What to watch: The next markers will be whether the team publishes validation data for VirCapSeq-ONT, identifies the geographic sites and arboviruses under surveillance, and shows how findings will be shared with veterinary, mosquito control, and public health networks over the grant’s 2024-2029 timeline.
