Vibrio vulnificus is a type of tiny living thing called a bacteria. It is found in saltwater and can make people very sick if they swallow it or get it in a cut on their skin.
This bacteria can make people sick in different ways depending on how it gets in their body. If someone swallows it, they can have tummy troubles like pain, vomiting, and diarrhea. If they get it in a cut on their skin, it can cause a very serious infection that can spread through the body and make people very sick. In some cases, it can even be deadly.
It is important to be very careful when you are near saltwater and avoid swallowing any of it or getting cuts that could expose you to the bacteria. People who have weaker immune systems, such as the elderly or people with certain medical conditions, are more at risk for getting very sick from Vibrio vulnificus. If you think you might have come into contact with this bacteria and start feeling sick, be sure to tell a grown-up right away and go see a doctor.
