Abstract: Health hazards in public places arise from a variety of physical, chemical, and biological factors, which can lead to the epidemics of infectious and non-infectious diseases. A comprehensive understanding of the characteristics of environmental health hazard factors in key public places will help further disease prevention and control, and health protection in public places, provide basic evidence for effectively reducing the health risk of vulnerable groups. This column presents the progress of health hazard surveillance projects in public places (such as hotels, waiting rooms, shopping malls and supermarkets, and barber and beauty shops) in recent years, including environmental sanitation problems, the impact of health hazard factors on the health of employees, and the effects of control measures againstcoronavirus disease 2019COVID-19, which is promising to strengthening health management and risk control in public places.
