Mucormycosis is an uncommon infection. In the United States, active population-based surveillance, conducted in 1992 and 1993, showed that mucormycosis developed in 1.7 persons per million population per year.
Nosocomial (healthcare-associated) outbreaks of mucormycosis have been reported, but most cases in hospitalized patients are sporadic and it is often difficult to determine whether or not these infections were acquired within the healthcare setting.
No national surveillance exists. Active surveillance is being conducted among hematopoietic stem cell and solid organ transplant recipients in selected U.S. hospitals.
