Overview

The most potent risk factor in the development of sporotrichosis is handling thorny plants, sphagnum moss, bales of hay, or any plant or plant product that can cause skin trauma. These risk factors either lead to direct inoculation or merely enable the entry of the fungus. Other risk factors include a weakened immune system, a history of alcoholism, and the handling of infected animals. [1]

Common Risk Factors

Less Common Risk Factors

  • Zoonotic transmission has been reported from insect bites, handling of fish, and bites from felines, birds, canines, rats, reptiles, and horses. Most commonly, incidents of zoonotic transmission result from transmission by infected cats[5]
  • Person-to-person transmission is rare. [6]
  • In Uruguay and Brazil, cases of sporotrichosis have been associated with armadillo hunting. [7]
  • Pulmonary sporotrichosis may result from fungal inhalation, although this form of sporotrichosis is rare.
