ԹϱHealth and GVN scientists presented research at the GVN regional meeting.

Virologists, public health leaders, and researchers convened to confront infectious disease challenges at the Global Virus Network Regional Meeting for the Caribbean and Latin America. 

Tracking dengue’s rise in Florida discussed at Global Virus Network event

Four different strains of the dengue virus, which is spread by mosquitoes in subtropical and tropical climates, have now been detected in Florida, according to Kristi Miley, PhD, research associate at the ԹϱCollege of Public Health. 

Dr. Miley’s findings show that the risk of dengue fever, including severe complications such as dengue hemorrhagic fever and dengue shock syndrome, is increasing in the state. She presented her research at the last month in Kingston, Jamaica.

Dr. Miley’s research surveyed data from Florida dengue cases from 2010 to 2024, comprising over 3,800 travel-related and over 500 locally acquired infections. She found that all four dengue serotypes are now being detected in Florida. 

“Our modeling links warming temperatures and increased travel with the expansion of Aedes aegypti and Aedes albopictus mosquitoes into central and northern Florida,” Dr. Miley said. “This trend is accelerating, and we need proactive, technology-informed public health responses.”

Her team is developing predictive models incorporating climate variables such as El Niño cycles and hurricane activity alongside mosquito surveillance data. They are also piloting a mobile app that allows users to photograph mosquitoes for AI-assisted species identification, empowering community participation in real-time vector monitoring.

Dr. Miley’s research addresses scientific complexity and operational challenges in Florida’s mosquito control systems, such as cryptic breeding habitats, post-storm debris and inconsistent practices across the state’s 67 counties.

The GVN Regional Meeting convened virologists, public health leaders and researchers across the Americas to confront the region’s most pressing infectious disease challenges, from vector-borne disease expansion to vaccine innovation and pandemic resilience. These issues are especially urgent given the close geographic, ecological and travel connections between Florida, the Gulf states and the Caribbean and Latin America, underscoring the need for coordinated regional responses to shared public health threats.

Strengthening Surveillance and Reframing Vaccines

Also at the meeting, Sten Vermund, MD, PhD, dean of the ԹϱCollege of Public Health and chief medical officer of the GVN, delivered opening remarks and emphasized the urgent need to strengthen viral surveillance systems across Latin America and the Caribbean, particularly in resource-limited settings vulnerable to emerging and climate-amplified diseases.

Dr. Vermund underscored the GVN’s efforts through the meeting to map viral response capacity across the region and use it as a strategic tool for pandemic preparedness, and he highlighted the importance of cross-border partnerships that promote equitable research leadership and knowledge-sharing. “Our aim is not only to share science but to forge actionable collaborations,” he noted.

Dr. Vermund also presented vaccinology breakthroughs while identifying current blind spots. While vaccines have nearly eradicated diseases like polio and smallpox, others like herpes simplex virus-2 (HSV-2), human T-cell leukemia virus (HTLV-1) and some emerging arboviruses do not yet have successful vaccines. He also said officials should reframe vaccine conversations to suggest that vaccines are not merely tools for preventing infection but also essential instruments for mitigating disease severity, reducing transmission and protecting public health.

“The only vaccine that immunizes is the one that’s administered correctly and equitably. Scientific innovation holds no real power unless it reaches every community as discovery must be matched by delivery and access,” he said.

The Microbiome–Virology–Oncology Nexus

Among the featured speakers was Christian Bréchot, MD, PhD, director of the ԹϱHealth Microbiomes Institute and vice chair of the GVN Board of Directors. Dr. Bréchot delivered a presentation urging the integration of microbiome science into the global virus
