摘要目的:了解全球信息流行病学相关研究主题、热点和发展趋势。方法:检索截止到2023年3月3日Web of Science核心合集数据库中收录的信息流行病学相关文献。利用VOSviewer 1.6.19可视化分析工具总结纳入文献的年度发表量、出版期刊、研究机构及作者信息等；并对出现频次前100的关键词进行共现聚类分析，分析研究热点主题与趋势。结果:截止到2023年3月3日，共检索到14 521篇文献。文献年度发文量2001年超100篇且呈逐年平稳增加趋势，2020年发表文献量由于COVID-19疫情出现了成倍增长且2021年达到峰值(2 593篇)，2022年有所下降(1 973篇)；出版文献数量前10位的期刊来自5个国家，出版量总计2 099篇(14.46%，2 099/14 521)；发表文献数量前10位的研究机构(除WHO外)来自4个国家，发文量总计2 943篇(20.27%，2 943/14 521)；发表文献数量前10位的作者来自中国和英国，发文量均在40篇以上，总计566篇(3.90%，566/14 521)；高频关键词聚类于4个重要领域[艾滋病(HIV/AIDS)、流行病学(epidemiology)、流行病(epidemic)和COVID-19]和3个热点主题(艾滋病公共卫生监测、流行病信息监测和COVID-19信息流行病)。结论:当前信息流行病学的研究热点集中于COVID-19的信息流行病管理，包括SARS-CoV-2、信息流行病、精神卫生和社交媒体等内容。今后将围绕公共卫生焦点问题以信息流行病管理方式开展流行病学相关研究。

abstractsObjective:To understand the topics, hotspots and trends of researches in the field of infodemiology.Methods:Based on Web of Science Core Collection, the literatures related to infodemiology were collected until March 3rd, 2023. With VOSviewer version 1.6.19, published features including numbers of annual published articles, journal, organization and author information were analyzed. Based on the top 100 keywords in frequency, cluster analysis was used to analyze the research hotspots and trends.Results:Until March 3rd, 2023, a total of 14 521 articles were retrieved. The annual number of published articles exceeded 100 in 2001 and showed an increasing trend in following years. In 2020, the number increased doubly due to the COVID-19, and reached the peak in 2021 (2 593 articles) and declined in 2022 (1 973 articles). The top 10 journals in publication number came from 5 countries, with a total of 2 099 articles (14.46%, 2 099/14 521). The top 10 research institutions (excluding World Health Organization) came from 4 countries, with a total of 2 943 articles (20.27%, 2 943/14 521). The top 10 authors publishing over 40 articles per person were from China and Britain, with a total of 566 articles (3.90%, 566/14 521). According to high frequency keywords, 4 key research fields including HIV/AIDS, epidemiology, epidemic and COVID-19, and the 3 hotspots including HIV/AIDS public health monitoring, epidemiology monitoring and COVID-19 information epidemic were clustered.Conclusions:The current hotspot of infodemiology focuses on the infodemic management of COVID-19 including SARS-CoV-2, infodemiology, mental health and social media. In the future, the research will focus on the public health and carry out epidemiological research in the way of information epidemic management.
