Abstract
The main objective of the present study is to summarize the research output about COVID-19. The search was conducted in Scopus, the largest abstract and citation database of peer-reviewed literature, and later it was analyzed on VOSviewer. Total 34716 research documents have been published about COVID-19 till September 2020. We focused on three parameters, i.e., co-authorship pattern, citations, and co-words analysis. Based on the total number of publications, h-index, total citations, and citations per document, we provided the list of the top ten authors, institutes, and countries. Based on the total number of publications, the top-ranked author is Wiwanitkit, V., and the top institute is Harvard Medical School, USA. It is worthy to note that more than 150 countries have contributed to research output. Based on the total publications, citations, and h-index, we provided details for each continent. Later, we provided the list of the top ten countries. The highest documents are published by the USA (25.35%). We analyzed the 343682 keywords from all publications to provide a general overview or the common trends in publications. We also analyzed the top 2000 most cited documents and provided the details of the top ten authors, institutes, and countries. Based on the VOSviewer' analysis, the information on the co-occurrence of words in titles, abstracts, and keywords is provided. This may help to depict the common trends in research publications. Based on the bibliometrics results, significant work has been published on pathogenesis, diagnosis, treatment, and prevention of this pandemic.
