Abstract：Objective To investigate the status of microbial contamination of indoor air and its influencing factors in hospitals in a certain district of Shenzhen City, and to provide a scientific basis for improving the quality of indoor air in hospitals. Methods From July 2019 to January 2020, Anderson six-stage impact microorganism sampler was used to collect 76 samples from indoor air of different districts of two comprehensive hospitals, and an on-site detection of the related air indexes (including temperature, relative humidity, PM10, PM2.5, CO and CO2) was performed. Results The median of total amount of bacteria in indoor air of hospital wards in summer was 117 (14-1,420) CFU/m3, and that of total airborne fungi was 124 (14-827) CFU/m3. The median of total amount of bacteria in indoor air of hospital wards in winter was 195 (57-509) CFU/m3, and that of total airborne fungi was 456 (127-678) CFU/m3. The study revealed that the common factors influencing microbial concentration of indoor air were season, temperature, relative humidity, CO2, PM10 and PM2.5. Conclusion The indoor airborne microbe pollution in the hospitals in a certain district of Shenzhen is slight, but countermeasures should be taken to improve the indoor air quality.
