Abstract:Abstract: OBJECTIVE To analyzes the current state and future trends of research on risk assessment of public health emergencies in China,providing policy basis for public health emergency management.METHODS Using the literature from China National Knowledge Infrastructure (CNKI)as database,and CiteSpace software was used for visual analysis,aiming at the co-occurrence of core authors, institutions,keywords,and mutation words in the literature,thereby explaining the research hotspots and future development trends in this field.RESULTS A total of315 literatures were retrieved.It was predicted that the overall development of this field in China shows an upward trend,and the cooperation among institutions was not close enough.The nodes of keywords such as “risk assessment”“emergency events”“public health”“infectious diseases”“risk management”“emergency management"and “health emergency”were relatively large,forming four main clusters focusing on risk assessment,public health risks,health emergency management,and government. CONCLUSION Emphasis should be placed on the development of the field of risk assessment for public health emergencies,strengthening the emphasis on information technology,utilizing big data to accelerate development,reinforcing scientific research in this field,and promoting cross-departmental collaborative development.It is essential to conduct risk assessment throughout the entire process of prevent,in-event,and post-event phases of public health emergencies,establishing a public health risk management system tailored to China's actual development needs.
