Key Points

Vibrio vulnificus is associated with high morbidity and mortality rates in the U.S., indicating urgent need for prevention.
The study reveals that risk factors for mortality include exposure to contaminated water and consumption of raw seafood.
Epidemiological analysis conducted from 2000 to 2022 provides a comprehensive overview of vibrio vulnificus cases.
Understanding the risk factors is vital for developing effective public health strategies to reduce mortality.

Abstract

Background Vibrio vulnificus is a foodborne and waterborne pathogen causing substantial morbidity and mortality; however, its epidemiology remains poorly understood. To inform prevention and control efforts, we characterized U.S. V. vulnificus epidemiology and identified risk factors for mortality.
