“…Some particular fungi are linked with the sick hospital syndrome, causing allergenic diseases nonspecifically, and come from construction dust or dust accumulated within ventilation [50][51][52][53]. Most invasive infections are acquired from indoor air [54]. e prevention and control of microorganism growth can reduce the human health risks from airborne microorganisms.…”

Hospitals tend to have high density of occupancy. Poor indoor environmental quality in hospital buildings can exacerbate the health problems of patients and also harm visitors and staff. This study investigated the environmental characteristics and ventilation affecting the concentration of microorganisms in multiple-bed hospital wards. The measurements were accomplished by using a biosampler and an open plate method at four wards, different positions of electric fans, and different times. Data were analyzed by t-test and MANOVA. The results revealed that the concentrations of airborne bacteria were higher than the concentrations of fungi. There were significant differences in the concentrations of bacteria and fungi between sampling times and between hospital wards (p<0.05), while no difference was observed by positions of electric fans. Correlations between the concentrations and other environmental parameters indicate that temperature, number of occupants, and humidity were physical factors associated with the concentrations of microorganisms. In addition, mostly, Gram-positive bacteria were observed. This indicates the conditions in buildings in the tropical climate, and regular housekeeping of all room areas is needed to prevent the growth of airborne contaminants and the related risks to patients, visitors, and staff.

“…Fungi, in particular, have a high capacity to disperse in the air, which can pose a significant risk to susceptible patients, especially those who are immunocompromised, such as hemodialysis patients. Exposure to pathogenic fungi present in the air can result in infections with adverse consequences for patient health (Venceslau et al, 2012;Sajjadi et al, 2018;Calumby et al, 2019;Souza et al, 2019). Therefore, minimizing the dispersion of aerosols containing pathogenic fungi in the hospital environment is essential to ensure the health protection of both patients and medical staff.…”

“…The microbiological analysis of environmental fungi, particularly of hospital airborne microbiota, is of great importance in the prevention of allergic diseases and healthcare-associated infections (HAI) in hospitalized patients, especially those with immunosuppression, whether acquired or induced by different therapies, and patients undergoing invasive procedures such as hemodialysis. In this regard, the lack of air quality control through environmental monitoring can lead to prolonged hospital stays and compromise patient recovery (Schiavano et al, 2014;Durán Graeff et al, 2017;Rostami et al, 2017;Sajjadi et al, 2018;Calumby et al, 2019;Zhao et al, 2022).…”

The presence of fungi in healthcare settings, including hemodialysis units, represents a significant risk for immunocompromised patients. This study aimed to investigate the occurrence of fungi in the air and water of a hemodialysis unit located in a tertiary public hospital in Maceió, Alagoas, Brazil. Over a period of three consecutive months, monthly air samples were collected and analyzed using the spontaneous sedimentation technique on Petri dishes containing Sabouraud Dextrose Agar (SDA). Simultaneously, water samples (100 mL) were collected from four specific water distribution points and subjected plating on SDA. Fungi were phenotypically identified based on their macroscopic and microscopic characteristics. In total, 498 colony-forming units (CFUs) of fungi were isolated, with 86 CFUs originating from the air and 412 CFUs from the water. Regarding the water samples, a higher concentration of fungal CFUs was observed in the potable water from the supply network (229 CFUs). Unexpectedly, 23 CFUs were identified in the reverse osmosis samples and 11 CFUs in the storage tank, which are post-treatment points where the presence of microorganisms is not desired. The fungus Cladosporium spp. was the most prevalent in both air and water samples, followed by Penicillium spp. in the air and Rhodotorula spp. in the water. These findings underscore the need to implement effective control and monitoring measures for fungi in the hemodialysis unit to ensure patient safety.

Context: Today, the emergence of fungal infections in public places has become a focus, especially in developing countries. Objectives: The present study aimed to study the literature on fungal infections in public places in Iran to find a variety of fungal infections. Study Selection: A search was performed to identify relevant studies in PubMed, Web of Science, Scopus, Scientific Information Database (SID), and Magiran databases from 2010 to 2022 using special keywords and equivalents. Overall, 25 studies met the inclusion criteria. Finally, the required information was extracted and discussed. Results: The research findings indicate that the research design of most of the papers was cross-sectional. Most of the studies in the field of fungal infections in public environments in Iran have been carried out in places such as swimming pools, schools, some health-related environments, cultivation environments, and soil. Different species of Aspergillus, Penicillium, Mucor, and Mucormycosis were identified in the environments. Conclusions: Examination of different species showed a combination of superficial, skin, mucosal, and visceral fungal infections observed in public places. Prevention and environmental analysis should be given more attention by health policy-makers in order to reinforce public health.
