Infection caused by the Mucorales is most accurately referred to as mucormycosis, although the term zygomycosis may still be used by some sources. Mucormycosis is highly invasive and relentlessly progressive, resulting in higher rates of morbidity and mortality than many other infections. However, recent studies have suggested that mortality rates from mucormycosis have declined with newer therapies. A high index of suspicion is critical for diagnosis, and early initiation of therapy—often before confirmation of the diagnosis—is necessary to optimize outcomes.
