This state agency is responsible for monitoring public health and reporting infectious disease trends to residents.
The details
The bacteria typically enters the human body through open wounds, piercings, tattoos, or surgical incisions, though it can also be contracted by consuming raw or undercooked seafood. Infection symptoms often include fever, chills, and the appearance of red skin areas that may darken and blister, requiring treatment via antibiotics or surgical tissue removal.

Health Landscape
The 2026 case count follows the established seasonal pattern of the bacteria being most prevalent in warm water during the summer and early autumn. This data updates the ongoing monitoring of bacterial infections as temperatures influence the growth of Vibrio vulnificus in coastal regions.
Residents should avoid exposing unhealed cuts, tattoos, or piercings to water, as these can serve as entry points for the bacteria. If symptoms like fever, chills, or darkening skin blisters develop after water exposure, medical attention should be sought immediately for potential antibiotic or surgical treatment.
The takeaway
Public awareness of wound care and proper seafood preparation remains the primary defense against this bacterial infection. Residents should continue to exercise caution when entering coastal waters during the peak months of May through October.
