Microbial quality assessment of indoor air in a large hospital building during winter and spring seasons

Sensitivity of hospital building environment due to presence of potential sources of wide range of airborne microbes, make it a complex environment. Present study aimed to investigate seasonal (winter & spring) variation in airborne microbial levels as well as species on various locations (i.e....

Description
Summary:Sensitivity of hospital building environment due to presence of potential sources of wide range of airborne microbes, make it a complex environment. Present study aimed to investigate seasonal (winter & spring) variation in airborne microbial levels as well as species on various locations (i.e. operation theatres (OT1 & OT2), wards (GMW & SW), out-patient department (OPD) and emergency services (ES)) of a large hospital building. Air samples were collected during peak hours, twice a week, covering one month of each season. Statistically significant variation (p > 0.05) in bacterial concentrations over two seasons was found only for OPD. However, fungal concentrations significantly varied (p
