我国传染病预警研究热点及趋势的可视化图谱分析

Visual atlas analysis of research hot spots and trends of infectious disease early warning in China

目的对2001—2022年我国传染病预警方向的科研成果进行梳理,分析我国近20年来传染病预警的研究热点及趋势,旨在为相关政策及探索方向提供参考依据。方法以CNKI中文数据库检索出的相关文献作为数据来源,运用Excel 2019和Citespace 6.1.R2软件进行研究热点和前沿的文献可视化分析。结果共获得符合要求的文献1276篇,其中作者间多以小组进行研究,相互合作较少。研究机构类型较为单一,大部分以国内高校为主。“传染病”“预警”“预测”是出现频次最大的关键词;大数据及新冠肺炎疫情防控是目前的研究前沿。结论我国传染病预警领域作者及机构间合作较少,利用大数据预警传染病及提高早期预警新冠肺炎的能力是目前的主要研究方向及趋势。

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.
