The severe forms of sporotrichosis (those that affect the lungs, bones or joints, or central nervous system) usually affect people with weakened immune systems or other diseases including diabetes, chronic obstructive pulmonary disease (COPD), alcoholism, or HIV. For example, sporotrichosis outbreaks have occurred among forestry workers, people who work in tree nurseries and garden centers, and people who handle hay bales. People who touch plant matter such as sphagnum moss, rose bushes, or hay are more likely to become infected.
