Abstract：Objective To monitor the airborne fungi contamination of indoor and outdoor during and after the construction works of a Grade-A hospital,and to provide risk assessment basis for the prevention of invasive fungal infection related to the construction of the hospital.Methods From September 2022 to March 2023,eight indoor and outdoor sampling points were selected near the construction to monitor hospital airborne fungi contamination.The plate sedimentation method and plank-tonic bacteria sampler method were used to monitor the indoor and outdoor of airborne fungal concentration,respectively.Results During the construction period,the distance between the sampling point and the construction site increased,and the airborne fungi concentration decreased accordingly.The airborne fungi concentration of indoor was lower than that of out-door.The colony-forming unit(CFU)of airborne fungi in the general pediatric ward was higher than that of the neonatal ward,while that of the neonatal ward was higher than that of the operating room.One month after the construction,the air-borne fungi contamination of the indoor and outdoor was significantly reduced.Conclusion The concentrations of fungi in in-door and outdoor air increased significantly during the construction of hospital construction site.Implementation of effective infection prevention measures can significantly reduce the airborne fungi contamination in high-risk departments.
