"Aspergillus terreus" infection can lead to superficial infections in humans. These affect the outside layer of the body. It is commonly isolated from onychomycosis which is infection of human skin and nails. The incidence of onychomycosis as a result of "A. terreus" (not the common agent dermatophyte) is increasing. This happens to be the most frequently reported superficial infection in clinics and hospitals. Another common superficial infection caused by "A. terreus" includes otomycosis (ear infection), which is mostly isolated from patients who had recent surgical operations.
