What is sporotrichosis?

Sporotrichosis is a skin infection caused by a fungus. The fungus lives in soil, plants, wood, and garden material. It enters your skin through small cuts caused by thorns, splinters, or other sharp objects.

What increases my risk for sporotrichosis?

  • Any work with plants and soil, such as gardening or working in a greenhouse
  • Handling or playing in hay bales
  • Work with pine needles or wood
  • Medical conditions, such as a low immune system

What are the signs and symptoms of sporotrichosis?

The infection may start as a small red, pink, or purple bump, usually on your finger, hand, or arm. Other bumps may appear in a few days or weeks. The bumps may slowly grow and form into pus-filled blisters. The bumps break open and become skin ulcers that heal slowly.

How can I manage my symptoms?

  • Cover the sore with a loose bandage to protect the wound.
  • Apply heat on your sore for 20 to 30 minutes, up to 4 times a day. Heat helps decrease pain and promotes healing.

How can I help prevent sporotrichosis?

  • Wear long sleeves, pants, shoes, and gloves when you work with plants and soil.
  • Wash your hands after you handle plants and soil. Use soap and water every time. Rub your soapy hands together, lacing your fingers. Wash the front and back of your hands, and in between your fingers. Use the fingers of one hand to scrub under the fingernails of the other hand. Wash for at least 20 seconds. Rinse with warm, running water for several seconds. Then dry your hands with a clean towel or paper towel.

When should I call my doctor?

  • You have a fever.
  • Your sores are not better even after you take medicine for 2 weeks.
  • Your sores are red, swollen, or draining pus.
  • You have questions or concerns about your condition or care.
