Research progress on the sources，transmission risks and monitoring technologies of airborne pathogens in the built environment

Abstract

Abstract:

The threat of airborne pathogens to human health has been highlighted in the context of the frequent occurrence of respiratory pandemics，such as SARS，H1N1 influenza，etc. The characteristics of high airtightness and high population density in the built environment，along with the impact of the ventilation system on the growth and transmission of pathogens，have increased the complexity of pathogen transmission.All these factors pose higher requirements for identification and monitoring technologies. This paper focuses on airborne pathogens and provides a review from three aspects：sources，transmission risks and monitoring technologies，with the aim of improving the ability of early identification and monitoring of pathogens in the built environment，providing a reference for in-depth study of transmission mechanisms，and responding to the spread of unknown diseases caused by novel pathogens.

Key words: Airborne pathogens, Built environment, Transmission risk, Monitoring technology, Ventilation
