Background: Hospitals are among the most susceptible places to the distribution of bioaerosol-related infections given their potential for a high microbial density and Low immunity of a number of patients. Accordingly, the investigation of the types and concentration of fungal bioaerosols, as well as the implementation of periodic monitoring and constant control, in hospitals can play a significant role in controlling nosocomial infections. Regarding this, the aim of the present study was to investigate the types and concentration of fungal bioaerosols in the indoor air of different units of three teaching hospitals. Methods: This descriptive cross-sectional study was conducted on 272 samples obtained from selected units, with an emphasis on the special units of three teaching hospitals, during the first six months of 2016. The sampling was performed using the Quick Take 30 sampler according to a standard method recommended by the National Institute for Occupational Safety and Health (0800), as well as the Andersen single-step sampler. After identification by standard methods, they were analyzed. Findings: The mean fungal concentrations were estimated at 96, 65, and 44 CFU/m3 in the H1, H2, and H3 hospitals, respectively. Accordingly, the air quality of the different units under investigation was ranked intermediate based on the standard of the European :union: Good Manufacturing Practice. The results demonstrated a strong correlation between population density and fungal concentration in the indoor air of H1 and H3 hospitals. Based on diagnostic findings, Penicillium, Aspergillus, Cladosporium, and Alternaria species were the most common fungi in the studied hospitals. Conclusion: Based on the findings, the periodic monitoring and constant control of fungal bioaerosols in the indoor air of hospitals should be prioritized in the hospital management process. This end can be accomplished by the establishment of active committees controlling infection and environmental health.
