Sporotrichosis is an infection of the skin caused by a fungus from rose thorns, hay, moss, and soil. Most people who have sporotrichosis only in their skin or lymph nodes make a full recovery.
Treating a sporotrichosis infection may take several months or years, and scars may remain at the site of the original infection.
Infections involving the brain, lungs, joints, or other areas of the body are much more difficult to treat.
