Sources of C. neoformans
Where does C. neoformans live?
How does someone get a C. neoformans infection?
C. neoformans infections are not contagious. Humans and animals can get the infection after inhaling the microscopic fungus from the environment. Some research suggests that people may be exposed to C. neoformans in the environment when they are children.3 Most people who breathe in C. neoformans never get sick from it. However, in people who have weakened immune systems, C. neoformans can stay hidden in the body and cause infection later when the immune system becomes too weak to fight it off.4
