Public Health Crisis Management Caused by COVID-19: A Scientometrics Review.

The COVID-19 pandemic was one of the most serious public health events of the 21st century, which had a profound impact on the entire human society and sparked extensive debate and research on public health crisis management. To clarify the development path of the issue and to discover the structure and internal logic of related studies, this study conducted a scientometric analysis (co-citation analysis, co-occurrence analysis, cooperation network analysis, knowledge domain migration analysis) of 8814 publications from the Web of Science Core Collection and PubMed using CiteSpace, and drew the following conclusions: (1) The research focuses on empirical studies in medicine and other fields, and expands to non-medical fields such as "social media", "COVID-19 lockdown", and "air quality"; (2) The USA, UK, Italy and other major developed countries in Europe and America are leading the research trend, while developing countries, notably China, India and Brazil have become the important contributors to the study of this issue in different ways; (3) The research results at this stage are mainly in the fields of medicine, health and biology and are cited internally, but are also developing in the direction of economics, political, environmental and other fields. Finally, this study summarises some of the issues that should be of concern to public health crisis management in the post-pandemic era, in the hope of providing some insight for researchers on this issue.
