RESERVOIRS OF FUNGI IN INDOOR ENVIRONMENTS: A GUIDE FOR EXPOSURE REDUCTION

Abstract: Our previous studies investigating the fungal ecology of the indoor environment identified significant hard surfaces, upholstered furniture and pet area reservoires of potential opportunistic fungi, and emphasized the importance of cleaning, disinfection, and climate control in the maintenance of a healthy environment. The most frequent identified species were Cladosporium, Aspergillus, Penicillium, Fusarium, Alternaria, which present a health risk. A comprehensive guide for reducing this risk has beeen developed. Recommendations include: 1) control moisture in the air and on surfaces, 2) clean reservoirs by removing soils, dusts, and other potential growth substrates, 3) prevent amplification of residual fungi remaining after cleaning by using a disinfectant, 4) restrict pollutant built-up and entry from outside the home, and 5) use air-cleaning devices. These practices should be mostly implemented in buildings inhabited by susceptible persons (children, eldery, immunocompromised)
