GALVESTON – The Galveston County Health District has issued a public health alert due to an increase in Vibrio bacteria infections, a group of bacteria commonly found in marine environments.
Vibrio bacteria are naturally found in warm coastal seawater and are more prevalent in the summer months when the water is warmer.

The GCHD has reported an increase in severe wound infections from Vibrio vulnificus and gastrointestinal illnesses from Vibrio parahaemolyticus, along with cholera-related illnesses from Vibrio cholerae. Health officials are actively investigating the sources of these infections and implementing measures to prevent further cases.
Dr. Phillip Keiser, Local Health Authority and CEO of GCHD, emphasized the importance of common sense precautions.
“While Vibrio bacteria can be present in Galveston waters, there’s no need to panic. Use common sense: avoid raw seafood, practice good hygiene, and stay informed to keep safe.”
According to the GCHD, recent reports have shown a rise in Vibrio-related cases in the area, prompting a close collaboration with the University of Texas Medical Branch to address the issue.
Types of Vibrio Bacteria and associated risks
There are several species of Vibrio bacteria that can cause infections, including Vibrio cholerae, Vibrio parahaemolyticus, and Vibrio vulnificus. Each species can lead to different symptoms and health risks:
- Vibrio cholerae: Causes cholera, characterized by severe diarrhea, vomiting, and dehydration.
- Vibrio parahaemolyticus: Leads to gastroenteritis with symptoms such as diarrhea, abdominal cramps, nausea, and vomiting.
- Vibrio vulnificus: Can cause severe wound infections, potentially life-threatening, especially in individuals with weakened immune systems or liver disease.

Preventive measures
To protect against Vibrio infections, the GCHD recommends the following precautions:
- Ensure seafood is thoroughly cooked before consumption, particularly avoiding raw shellfish from areas with reported outbreaks.
- Wash hands thoroughly with soap and water, especially after handling raw seafood.
- Pay attention to local health advisories regarding water quality and seafood safety.
If you experience symptoms consistent with a Vibrio infection, such as severe gastrointestinal distress or wound infections following exposure to seawater, seek medical attention promptly.
