Introduction: Mapping scientific production on COVID-19 is becoming an essential activity, due to the growing increase in the number and impact of publications on the topic. Objective: To characterize global scientific production on COVID-19 in 2020 and 2021 years. Method: A bibliometric, descriptive and retrospective research was carried out with a sample of 4000 articles, obtained from the Web of Science and Scopus databases from January 2020 to November 2021. Bibliometric indicators were calculated through the Bibliometrix R software and the managers of these bases themselves. Results: The article with the highest number of citations received was “Clinical Course and Risk Factors for Mortality of Adults in Patients with COVID-19 in Wuhan, China: A Retrospective Cohort Study”. The authors with the highest number of publications were Mahase with 244 articles in Scopus and Zhang with 487 publications in Web of Science. The largest number of publications corresponded to International Journal of Environmental Research and Public Health. Original articles were the most frequent and United States, China and the United Kingdom stood out among the countries. Conclusion: The study allowed us to know the main bibliometric indicators about the scientific production caused by the COVID-19 pandemic in the years 2020-2021, which corroborated the enormous work carried out worldwide by scientists to try to decipher and control the virus, where international and interagency collaboration reached extraordinarily high levels.
