About Vibrio vulnificus 

  • It is a type of bacteria that can cause a fatal infection. 
  • This infection can happen when a wound comes into contact with raw or undercooked seafood, its juices, or its drippings or with saltwater.
  • It eats away at the skin, muscles, nerves, fat and blood vessels around an infected wound.
  • In severe cases, it can lead to septicemia, which is when the bacteria enter the bloodstream.
  • It results in a septic shock, where blood pressure drops dangerously.
  • Signs and symptoms include:
    • Watery diarrhea, often accompanied by stomach cramping, nausea, vomiting, and fever.
    • For bloodstream infection: fever, chills, dangerously low blood pressure, and blistering skin lesions
    • For wound infection: Fever, redness, pain, swelling, warmth, discoloration, and discharge (leaking fluids).
  • The only method available to avoid getting infected with the bacteria is to avoid coming in contact with it.
  • It is advised to make sure any seafood you consume is well-cooked, avoid raw or undercooked oysters and clean your hands after handling any kind of seafood.


Q1) What is sepsis?

It is a serious medical condition characterized by a widespread infection throughout the body. It occurs when harmful bacteria or other pathogens enter the bloodstream and trigger a systemic response from the body's immune system. Septicemia can lead to a life-threatening condition if not promptly treated.
