Visual atlas analysis of research hot spots and trends of infectious disease early warning in China / 公共卫生与预防医学

ABSTRACT

Objective To sort out the scientific research achievements in the direction of early warning of infectious diseases in China from 2001 to 2022, and analyze the research hotspots and trends in the direction of early warning of infectious diseases in China in recent 20 years, so as to provide reference for relevant policies and exploration directions. Methods Relevant literature retrieved from CNKI Chinese database was used as the data source, and Excel 2019 and Citespace 6.1.R2 software were used for visual analysis of research hotspots and frontier literature. Results A total of 1276 papers meeting requirements were obtained, and most of the research groups were relatively small and had little cooperation with others. The types of research institutions were relatively single, and most of them were domestic universities. “Infectious diseases”, “early warning” and “prediction” were the most frequently used keywords. Research on big data and COVID-19 epidemic prevention and control is the current research frontier. Conclusion There is little cooperation among authors and between institutions in the field of early warning of infectious diseases in China. Using big data to early warning of infectious diseases and improving the ability of early warning of COVID-19 are the main research directions and trends at present.
