Galveston health officials note low Vibrio cases amid regional surge

Galveston County health authorities said five cases of Vibrio vulnificus infection have been confirmed this year, two of which required hospitalization but have since recovered. The bacteria, sometimes called “flesh-eating,” can enter open wounds or be ingested through raw oysters, posing higher risks to people with liver disease or weakened immune systems.

"It can get into wounds and cause severe infections of people’s limbs, and it can spread all over the body," said Dr. Philip Keiser, the county’s public health officer. He added that the other common route of infection is through consuming raw oysters.

Louisiana health officials have reported nine cases this year, with five deaths, prompting concerns about a regional rise in the pathogen. Keiser noted that Galveston’s numbers remain within the typical range of about ten cases annually, but warned that warmer water and higher salinity—conditions that can be amplified by heavy rain runoff—favor bacterial growth.

Local residents expressed mixed reactions. Some beachgoers said the news did not deter them, while others said they would avoid the water if they had open cuts. Keiser recommended checking the federally funded Beach Watch program, which provides real-time bacterial monitoring, and advised looking for visible signs of runoff or fecal material in the water.

"You can go look along the beach to see whether there’s basically fecal material in the waters," Keiser said.

The health department emphasized that awareness and basic precautions, such as covering wounds and avoiding raw shellfish, remain the most effective ways to reduce risk.
