Could Vibrio Infection Be the Cause of Pain After Fish Sting? - Surgery

Is it possible to contract Vibrio species from being stung by a venomous fish (such as a stonefish)?


After being stung by a venomous fish, I went to the emergency room where I received treatment for cellulitis and applied medication.
The redness and swelling lasted for about three days before subsiding and the pain resolved.
By the sixth day, I had healed.
However, on the seventh day, when I pressed on the wound, it became swollen again and is now painful.
I'm unsure if this is due to the venomous fish or if it could possibly be caused by Vibrio species.
I would appreciate your advice, doctor.

Hello! It is recommended to see a surgeon to assess whether debridement is necessary.
It has already been a week, and the specific strain of bacteria is no longer as important.
What matters is timely debridement to prevent further complications.
Take care! Changhua Hospital is concerned about you!

When it comes to the concern of whether a Vibrio infection could be the cause of pain after being stung by a venomous fish, it is essential to consider several factors, including the nature of the injury, the symptoms experienced, and the potential for infection.

Firstly, it is important to understand that Vibrio species, particularly Vibrio vulnificus, are bacteria commonly found in marine environments, especially in warm coastal waters. These bacteria can cause severe infections, particularly in individuals with compromised immune systems, such as those with liver disease or diabetes. However, the likelihood of contracting a Vibrio infection from a fish sting is relatively low unless there is a direct exposure to contaminated water or the wound is exposed to seawater.

In your case, you mentioned experiencing redness, swelling, and pain following the sting, which are common inflammatory responses to injury. The initial symptoms you experienced for about three days, followed by a resolution, suggest that your body was responding to the injury rather than an infection. The fact that the pain and swelling returned after a week, especially upon applying pressure to the area, raises the possibility of a localized inflammatory response or a secondary infection.

It is crucial to note that while Vibrio infections can occur through open wounds, they typically present with more severe symptoms, including fever, chills, and systemic signs of infection. If you were to develop such symptoms, it would warrant immediate medical attention. In the absence of systemic symptoms, it is more likely that your pain is due to residual inflammation or irritation at the site of the injury rather than a Vibrio infection.

To further assess the situation, it would be advisable to monitor the wound closely for any signs of infection, such as increased redness, warmth, swelling, or discharge. If these symptoms develop, or if you experience fever or chills, it would be prudent to seek medical evaluation. A healthcare provider may consider performing a wound culture or prescribing antibiotics if an infection is suspected.

In summary, while it is theoretically possible for a Vibrio infection to occur after a fish sting, the likelihood is low unless there are specific risk factors present. Your symptoms appear to be more consistent with a localized inflammatory response. However, continued monitoring and consultation with a healthcare professional are recommended to ensure proper healing and to rule out any potential complications.
