Objective: to analyze the global development of scientific publications and build topics covered in research on the new coronavirus/COVID-19. Methods: review of abstracts of publications on the new coronavirus/COVID-19 with search in the Embase and Web of Science databases, on November 3, 2020. Data were analyzed by modeling the research topics using Latent Dirichlet Allocation (LDA) method. Results: a total of 31,769 publications were analyzed, involving researchers from 182 countries. The studies were published in 5,336 different journals. The analysis identified 20 main research topics on the new coronavirus/COVID-19, with more than half (54.5%) covering topics of impacts and challenges resulting from the pandemic (11.3%), immune response (9.6%), potential therapies (9.0%), epidemiology (7.8%), mental health (6.3%), recommendations for assistance with other health needs (5.3%), and clinical complications. The theme of telemedicine and telehealth was present in 4.2% of publications. Conclusions: scientific publications were distributed among 20 main themes, characterizing their importance and relevance in understanding the disease in question to outline strategies for control, prevention, treatment and attention to diseases/implications resulting from the pandemic. Studies on primary care measures/primary health care were identified as the main knowledge gap.
