The COVID-19 pandemic has turned our life topsy-turvy. It has bought a massive change in all sectors around the world. A great number of research papers have already been published accounting for various aspects of the COVID-19 issue, owing to the ever-increasing interest in this hot area. The essential data is gathered using the well-known and dependable search engine SCOPUS. We looked at research papers, journals, and reviews from 25 leading countries to highlight a comprehensive study of research output through COVID-19 papers. This study focuses on the top authors, leading articles, and journals from various nations, the percentage of published papers in various fields, and the top collaborative research work from different authors and countries. USA, UK, China, Italy, and India have all made a significant contribution to COVID-19 research. The USA is the leading country followed by UK and China but for H-index China is in the best position. The highest number of papers has been developed in the area of "medicine". The Harvard Medical School of the UK contributed the highest number of papers followed by the University of Toronto of Canada. Professor K. Dhama of India has published the highest number of papers while C. Huang of China received the highest number of citations. It also highlights that several authors have differing opinions on the efficacy of taking the medicine remdesivir. Our research provides a complete and comprehensive image of the virus's current research status, or in other words, a roadmap of the present research status.
