What is cryptococcal disease?
Cryptococcal disease is an infection caused by an unusual type of fungus, Cryptococcus. There are three main types of Cryptococcus that cause disease: C.gattii, C. grubii, and C. neoformans. Whereas C. neoformans and C. grubii cause illness predominantly in people with impaired immune systems, C. gattii can cause illness in otherwise healthy people as well as those with impaired immunity. Although infection is rare, several Washington residents were recently infected by C. gattii. The fungus can affect a person’s lungs (pneumonia) or nervous system (meningitis). In rare cases, the infection can be fatal. Animals, including pets, also can develop cryptococcal disease. Where is this fungus found? C. gatti lives on trees and in the soil. Does Cryptococcus gattii occur in Washington? C. gattii has been found in the environment in Washington. The Washington State Department of Health has had reports of animals and humans who have acquired the infection in the state. How are people exposed?
