Hurricane Isaias Threatens US Coast With Floods and Flesh-Eating Bacteria
Officials warn millions in Florida and along the Gulf Coast to be aware of Vibrio vulnificus risks following storm surge.
Hurricane Isaias is poised to make landfall on the U.S. coast, bringing with it the potential for devastating floods and high winds, while public health officials are issuing urgent warnings about the increased risk of flesh-eating bacteria.
Florida Governor Ron DeSantis stated Thursday that the state was preparing for Isaias to arrive as a Category 3 storm by Friday evening or early Saturday. Forecasters anticipate monster storm surges of up to seven feet along the Northern Gulf Coast, raising concerns that floodwaters could carry the bacteria inland.
The Florida Department of Health has cautioned that "following a storm, such as a hurricane, floodwaters and standing water pose risks for Vibrio vulnificus exposure." The bacteria can enter the human body through open wounds, and severe infections can rapidly destroy tissue, leading to septic shock and potentially death within a short period.
Dr. Norma Beatty of the University of Florida College of Medicine noted that Vibrio infections have historically seen an increase after hurricanes. "Storm surge waters from the Gulf breach into our neighborhoods and even into our homes, where people are now possibly trudging through water that contains the bacteria," Beatty explained. She advised that any cuts exposed to storm surge water should be thoroughly cleaned and monitored for signs of infection.
Data from previous hurricane seasons in Florida illustrates a concerning trend. In 2022, the year Hurricane Ian struck, Florida recorded 74 Vibrio infections and 17 deaths. The numbers were even higher in 2024, following hurricanes Helene and Milton, with 82 cases and 19 deaths. These figures represent a significant increase compared to the average of approximately 10 deaths annually between 2017 and October 8, 2026.
Chamteut Oh, an assistant professor at the University of Florida, highlighted the potential danger. "That could be a potential risk we should be worried about," Oh told the Tallahassee Democrat. "People may not know how exactly the level of bacteria goes up, but they should be aware [that] the pathogens can increase right after Isaias, and they can last a long time."
