Is coccidioidomycosis contagious?
No, the infection is not spread from person to person, or from animals to people. The infectious form of the fungus exists when the fungus grows in the environment. The fungus changes its form when it infects a person, and this form cannot be transmitted from one person to another.
It is important to note, however, that Coccidioides growing in culture as a mold in the laboratory may cause infection in laboratory personnel if the cultures are not handled properly and the appropriate precautions are not taken.
