After severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection, a series of symptoms may persist for a long time, which is now called long COVID. It was found that long COVID can affect all patients with COVID-19. Therefore, long COVID has become a hot topic. In this study, we used the WOS database as a sample data source to conduct a bibliometric and visual analysis of 1765 long COVID articles over the past three years through VOSviewer and R package. The results show that countries/authors in Europe and The United States of America contribute most of the articles, and their cooperation is also the most active. Keyword co-occurrence identified four clusters, with important topics including the mechanism, clinical symptoms, epidemiological characteristics, and management/treatment of long COVID. Themes such as "cognitive impairment", "endothelial dysfunction", "diagnosis", and "biomarkers" are likely to be the focus of new attention in the coming period. In addition, we put forward the possible research opportunities on long COVID for researchers and practitioners to facilitate future research.
在严重急性呼吸综合征冠状病毒2（SARS-CoV-2）感染后，一系列症状可能会长期持续，现在这被称为“长新冠”。研究发现，“长新冠”会影响所有新冠肺炎患者。因此，“长新冠”已成为一个热门话题。在本研究中，我们以Web of Science（WOS）数据库作为样本数据源，通过VOSviewer和R包对过去三年的1765篇关于“长新冠”的文章进行了文献计量和可视化分析。结果表明，欧洲和美国的国家/作者贡献的文章最多，他们之间的合作也最为活跃。关键词共现确定了四个聚类，重要主题包括“长新冠”的机制、临床症状、流行病学特征以及管理/治疗。“认知障碍”“内皮功能障碍”“诊断”和“生物标志物”等主题可能是未来一段时间新的关注焦点。此外，我们为研究人员和从业者提出了关于“长新冠”可能的研究机会，以促进未来的研究。
