The Covid-19 pandemic has been the highest disruptive event in the world recent history. Worldwide academic research on this topic has led to an explosion of scientific literature, never seen before. Bibliometrics provide methods to illustrate this exceptional phenomenon in academic publications. The objective of this paper is to analyze the Covid-19 research from a bibliometric perspective and to study the impact of the publication explosion on bibliometric indicators. The present study shows how an exceptional phenomenon has a disruptive impact on bibliometric indicators, such as the h-index and the Journal Impact Factor. The higher the specialization, the higher the possible impact of a disruptive phenomenon. In applied sciences, more important than the research or the discipline, the specific theme of the research is crucial for citations of articles and for their impact. The salience of the topic, the magnitude of the problem at study and the urgency to find solutions are drivers for citations. The study of the Covid-19 research illustrates the relativity of indicators and the need for context. The present study also confirms the plead for responsible metrics of the San Francisco Declaration on Research Assessment (DORA).

Covid-19 大流行是世界近代史上最具破坏性的事件。世界范围内关于这个主题的学术研究导致了前所未有的科学文献的爆炸式增长。文献计量学提供了在学术出版物中说明这种特殊现象的方法。本文的目的是从文献计量学的角度分析 Covid-19 的研究，并研究出版物爆炸式增长对文献计量学指标的影响。本研究展示了一种特殊现象如何对文献计量指标产生破坏性影响，例如 h 指数和期刊影响因子。专业化程度越高，破坏性现象的可能影响就越大。在应用科学中，比研究或学科更重要，研究的特定主题对于文章的引用及其影响至关重要。主题的重要性、研究问题的严重性以及寻找解决方案的紧迫性是引文的驱动因素。对 Covid-19 研究的研究说明了指标的相关性和背景的必要性。本研究还证实了旧金山研究评估宣言 (DORA) 对负责任指标的呼吁。
