Sources of Cryptococcosis
How is someone infected with Cryptococcus neoformans?
C. neoformans spores are typically found in bird droppings (especially pigeon droppings) or in soil contaminated with bird droppings. Humans can become infected after inhaling microscopic, airborne fungal spores from the environment. Cryptococcosis is not known to be spread from person to person, from animal to animal, or from animals to humans.
