Vibriosis is an infection caused by bacteria from the Vibrio genus, commonly found in warm seawater. People can become infected by consuming raw or undercooked seafood, especially oysters, or through open wounds exposed to contaminated water. Symptoms may include diarrhea, abdominal cramps, nausea, vomiting, fever, and chills. The most common types of vibriosis are caused by Vibrio cholerae and Vibrio parahaemolyticus. While many infections are mild, some can lead to severe illness, particularly in individuals with weakened immune systems or chronic liver disease. Prompt medical attention is essential for those experiencing severe symptoms.
