Abstract EN
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.
