The model, led by Bailey Magers and Sunil Kumar, achieved 72% accuracy in Florida test runs and flagged over 80% of post-hurricane vibriosis cases in 2024.
It uses CDC illness data and satellite measurements to forecast high-risk areas a month in advance, aiming to alert public health departments and supplement existing shellfish safety protocols.
As climate change warms coastal waters, Vibrio infections are expanding northward, posing increasing risks to beachgoers and the shellfish industry, with annual U.S. cases estimated at 80,000 and about 100 deaths.

This deadly bacteria may reach New York by 2060. Are we prepared?
A simple beach cut can be fatal. Are emergency rooms ready for this threat?
Is the media's 'flesh-eating bacteria' panic worse than the actual risk?
We can predict deadly outbreaks, but are we ignoring the climate crisis that fuels them?
University of Florida’s Vibrio vulnificus Predictive Model Achieves 47% Precision in Forecasting Post-Hurricane Outbreaks
Overview
The 2024 hurricane season, marked by Hurricanes Helene and Milton, caused massive coastal flooding in Florida, creating warm, brackish waters ideal for Vibrio vulnificus growth. This led to a dangerous spike in infections, which the University of Florida's advanced Bayesian predictive model successfully forecasted. Building on this success, UF is developing an AI-powered Vibrio Warning System using real-time NASA and NOAA satellite data to provide timely risk alerts. Climate change, driving rising ocean temperatures and more intense hurricanes, is expanding Vibrio habitats northward at about 48 km per year, increasing health risks and economic impacts on coastal communities. This integrated approach aims to protect vulnerable populations and support public health responses.
