The present study examines the intellectual structure of research on coronavirus in all years as revealed from an author cocitation analysis (ACA). Their efforts have drawn on knowledge and experiences accumulated from studying and fighting coronaviruses and outbreaks in the past, including the 2002 severe acute respiratory syndrome (SARS) and the 2012 Middle East respiratory syndrome (MERS) outbreaks. They have been trying to understand the novel virus and the impact of the pandemic on people’s mental and physical health and to find effective treatments and preventive measures. While citizens, organizations, and governments have been working together to contain the virus, doctors and scientists have been working around the clock to study the virus and the pandemic. The pandemic has disrupted social and economic systems worldwide, triggering a deep global recession ( Gopinath, 2020 Nicola et al., 2020 The New York Times Editorial, 2020). Results from this study should contribute to the understanding of the coronavirus research landscape and to the identification of strengths and weaknesses of current research on COVID-19.Īccording to public health data compiled by Johns Hopkins University ( ), as of August 14, 2020, just 5 months after the WHO declared the new coronavirus (COVID-19) a pandemic, more than 21 million cases of COVID-19 and 761,000 related deaths have been reported in 188 countries and territories. Notably, certain clinically important areas, such as mental health during outbreaks and viral surveillance, among others, did not stand out as identifiable specialties or topics in the coronavirus research landscape. The focus of research on major outbreaks is on public health and clinical research, with focus on disease characterization, diagnosis, transmission, and clinical course. The “outbreaks” dimension is by far the most prominent, dominated by reports on the three recent major outbreaks: COVID-19, severe acute respiratory syndrome, and Middle East respiratory syndrome. Four major dimensions are identified: I) outbreaks, II) viral structure and function, III) vaccine and therapeutic development, and IV) coronaviruses found in a range of animals. The present study examines the intellectual structure of research on coronavirus, as revealed from an author co‐citation analysis using citation data retrieved from the Web of Science Core Collection and mapped to the PubMed database. 2School of Library and Information Studies, University of Alberta, Edmonton, AB, Canada.1The Max Rady College of Medicine, University of Manitoba, Winnipeg, MB, Canada.Junyi Mei 1, Dangzhi Zhao 2 * and Andreas Strotmann 3
