As the continuous public health crisis, the communicable diseases of COVID-19, OMI and Monkeybox fallout are striking parallels to the whole world. The scope and duration of these disasters are unprecedented. The tourism industry has become one of the hit hardest industries, and research on tourism risks and safety of public health are more of big concerns in recent years. In this study, 751 SSCI articles on risk and tourism from 2008 to 2022 were selected through literature retrieval using the Web of Science core collection database, and visual analysis was performed using CiteSpace to show the knowledge evolution process, research hotspots and future trends in this field. The analysis results show that there has been an overall upward trend in the number of research studies on risk and tourism in the past 15 years. Secondly, there is an international trend toward cooperation between scholars. The main cooperation network centers are Australia, England, the United States and China. In addition, there are seven main clusters of research topics in the field of risk and tourism. Finally, the change of research hotspots is also closely related to catastrophic events. After the outbreak of the COVID-19, public health and the recovery of the tourism industry has attracted more and more scholars’ attention. By examining and analyzing the research content of risk, public health and tourism studies over the past 15 years, this study provides suggestions for the risk management of tourism and tries to predict the new development trend of tourism in the post-COVID-19 era.
