Summary Cryptococcosis is an invasive mycotic infection primarily affecting immunocompromised individuals. The objective of this study was to describe cryptococcosis mortality and associated medical conditions in the US for the period 2000–2010. Cryptococcosis‐related deaths were identified from the national multiple‐cause‐of‐death dataset. Mortality trends and comparison analyses were performed on overall cases of cryptococcosis and by subset [i.e. clinical manifestations of disease and human immunodeficiency virus ( HIV ) status]. A matched case–control analysis was also conducted to describe the associations between this disease and comorbid medical conditions. A total of 3210 cryptococcosi s ‐related deaths were identified. Cerebral cryptococcosis was the most commonly reported clinical manifestation of the disease. Approximately one‐fifth of the decedents ( n = 616) had a co‐diagnosis of HIV . Mortality rates were highest among men, blacks, Hispanics, Native Americans and older adults. Poisson regression analysis indicated a 6.52% annual decrease in mortality rates for the study period. HIV ( MOR = 35.55, 95% CI 27.95–45.22) and leukaemia ( MOR = 16.10, 95% CI 11.24–23.06) were highly associated with cryptococcosis‐related deaths. Cryptococcosis mortality declined significantly during 2000–2010. However, the disease continues to cause appreciable mortality in the US. With the majority of decedents having no HIV co‐diagnosis, there is still much to be learned about the epidemiology of this mycosis.
