What is Vibrio and how dangrous is it?

Key Points:

• Vibrio vulnificus, a potentially deadly bacteria previously found mainly along the Gulf Coast, is now being detected in northern areas including New York’s Long Island waterways.
• The bacteria thrives in warm salt and brackish water and can infect people through open wounds or by consuming raw or undercooked shellfish, posing serious risks especially to those with certain health conditions.
• Health officials have reported an increase in Vibrio cases this year, including severe infections like a critical case in South Mississippi, emphasizing the bacteria’s rapid tissue destruction and high fatality rate.
• People with open wounds, liver disease, diabetes, cancer, or weakened immune systems are most vulnerable and should avoid warm coastal waters, keep wounds covered, and seek immediate medical care if symptoms worsen after exposure.
• Experts warn that cuts to federal monitoring programs may hinder tracking of Vibrio outbreaks, and they advise thorough wound checks, proper cooking of shellfish, and vigilance for infection signs before and after water exposure.
