What is the Fisherman's Disease?

Fish-handler's disease, also known as "fisherman's disease," is a skin infection caused by the bacterium Mycobacterium marinum.

Understanding Fish-Handler's Disease

This infection typically develops when Mycobacterium marinum enters the body through cuts or scrapes in the skin. The primary cause is handling fish or shellfish where these minor skin injuries occur.

How Does the Infection Occur?

• Exposure: The bacteria live in aquatic environments, both freshwater and saltwater.
• Entry: When handling fish, especially during preparation, small cuts or scrapes can form on your hands.
• Infection: If Mycobacterium marinum comes into contact with these injuries, an infection can develop.

Key Characteristics

• Localized infection: It primarily affects the skin and underlying tissues at the site of the injury.
• Symptoms: The symptoms of fish-handler's disease might appear as reddish or purplish bumps or nodules on the skin which can sometimes ulcerate.
• Timeframe: Symptoms might take several weeks to develop after the exposure.

Prevention Strategies

To minimize the risk of infection:

• Wear Gloves: When handling fish or shellfish, always wear gloves to protect your skin.
• Clean Wounds: If you get any cuts or scrapes, wash them immediately with soap and water.
• Avoid Contact: When possible, avoid handling fish if you have open wounds on your hands.

Treatment

• Medical Evaluation: If you suspect you have fish-handler's disease, consult with a healthcare provider.
• Antibiotics: Treatment usually involves a course of antibiotics specific to this bacteria.
• Longer Treatment: Because of the nature of the bacteria, treatment might take longer to cure the infection.
