摘　　要：目的探索2019新型冠状病毒的研究现状、热点及变化趋势。方法计算机检索中英文数据库,中文数据库以中国知网(CNKI)为数据来源,英文数据库以Pubmed为数据来源,时间限定为2019-2020年(具体检索日期为2020年2月7日),收集所有关于2019新型冠状病毒是相关研究。再利用可视化软件CiteSpace 5.6.R2及VOSviewer通过共现网络分析方法对作者、发文机构及高频关键词进行聚类分析,探索和分析国内外新型冠状病毒的研究热点和前沿。结果计算机检索共获得中文文献132篇,英文文献103篇。通过共现分析的研究结果显示,中文研究作者分为两大团体,但团体与团体之间的相互合作很少;英文文献的研究作者分为8大聚类团体,第一作者均为国内作者并与少数的国外研究者有合作关系;中文文献发表的作者各机构之间的合作力度也相对缺乏,英文文献发表的作者机构与美国、新加坡有合作关系;中文文献主要关键词有"冠状病毒"、"感染防控"、"医院感染"、"防护"等,英文文献关键词包括"Coronavirus"、"2019-nCoV"、"Epidemiology"、"Coronavirus infections"、"Wuhan"、"China"、"Pneumonia"等。结论国内研究的研究热点集中在2019新型冠状病毒的感染防控和防护措施等内容,并向儿童的发病情况、新冠肺炎的抗病毒药物及相关指南的领域扩展;研究关于2019新型冠状病毒在武汉甚至中国及全球暴发的流行病学研究、新型冠状病毒肺炎的诊断等方面是主流问题,并向新型冠状病毒的分子学研究扩展。OBJECTIVE To explore the research status,hotspots and changing trends of SARS-CoV-2.METHODS The data sources were retrieved from the computer database,the Chinese database was based on CNKI and the English database was based on Pubmed,with the time limit ranging from 2019 to 2020(the specific search date was Feb.7,2020).All the literatures regarding to SARS-CoV-2 were collected,then the cluster analysis of authors,dispatch agencies and high-frequency keywords was performed by means of co-occurrence network analysis method based on the visualization software CiteSpace 5.6.R2 and VOSviewer,and the hotspots and frontiers of research on SARS-CoV-2 in China and abroad were explored.RESULTS Totally 132 Chinese literatures and 103 English literatures were included.The result of the co-occurrence analysis showed that the Chinese authors were divided into two groups,but there was little cooperation between the groups;the English authors were divided into eight clusters,all of the first authors were Chinese and had cooperative relations with a small number of foreign researchers;there was also a lack of cooperation among the institutions of the authors of the Chinese literatures,and the institutions of the authors of the English literatures had cooperative relations with the United States and Singapore.The major key words in the Chinese literatures included’coronavirus’,’infection prevention and control’,’hospital infection’and’protection’;the key words in the English literatures included’Coronavirus’,’2019-nCoV’,’Epidemiology’,’Coronavirus infections’,’Wuhan’,’China’and’Pneumonia’.CONCLUSION The hotspots of research in China focus on the control and prevention of COVID-19 as well as the protection measures and extends to the fields regarding to prevalence among children,antiviral drugs for COVID-19 and related guidelines;the hotspots of research focus on the epidemiology of COVID-19 outbreak in Wuhan,China and the globe as well as the diagnosis of COVID-19 and extends to the mol
