Fusarium species cause many infections in humans including locally invasive, superficial and disseminated infections. The clinical form of fusariosis depends largely on the immune status of the hot and the portal of entry, with superficial and localized disease occurring mostly in immunocompetent patients and invasive and disseminated disease affecting immunocompromised patients.Risk factors of severe fusariosis include prolonged neutropenia and T-cell immunodeficiency, especially in hematopoietic stem cell transplant recipients with severe graft versus host disease.
