Summary
Florida and Louisiana have logged 23 Vibrio vulnificus cases and 7 deaths this year, prompting Gulf Coast warnings to residents and visitors.
Warmer water, flooding and runoff can boost the bacteria in brackish coastal areas, health experts said, with hurricanes and other major weather events worsening conditions.
Open wounds exposed to coastal water can lead to fast-moving infections that turn life-threatening within 1 to 2 days; raw or undercooked oysters are another common source of vibriosis.
Florida reported 14 cases and 2 deaths so far in 2026, down from 33 cases and 5 deaths in 2025 and 82 cases and 19 deaths after Hurricane Helene in 2024.
Louisiana reported 9 cases and 5 deaths this year, versus an average of about 7 cases and 1 death annually over the previous decade, underscoring the danger for people with liver disease or weakened immune systems.
