Preventing exposure to moulds

Invasive fungal infections are a major cause of morbidity and mortality in patients with profound neutropenia or with severe immunosuppression. As Aspergillus and other mould species are ubiquitous, numerous reservoirs have been identified. Mould infection in susceptible patients results basically from respiratory exposure to conidia present in the air and on objects that surround the patients. In this review, protective environmental measures directed at airborne transmission and other less frequent mechanisms of transmission of moulds, as well as their effectiveness, are analysed.
