The COVID-19 outbreak originating in Wuhan, Hubei province, China, coincided with chunky, the period of mass migration for the annual Spring Festival. To contain its spread, China adopted unprecedented nationwide interventions on January 23, 2020. These policies included large-scale quarantine, strict controls on travel, and extensive monitoring of suspected cases. However, it is unknown whether these policies have had an impact on the epidemic. We sought to show how these control measures impacted the containment of the epidemic. Web of Science database was searched on September 10, 2020, for COVID-19 publications published between 2019 to 2020. It was performed on the same day to avoid the possible bias from an update on the database because the metrics are changing over time. All publication types were considered; however, publications as errata were excluded. Analysis parameters include a year of publication, publication type, patterns of international collaboration, research institutions, journals, impact factor, h-index, language, and times cited. A total of 17,133 COVID-19 research publications were published across the world. The (COVID-19) associated publications were originated from 25 countries/ territories, indicating the international spread of Corona virus COVID-19 research. The USA was the largest contributor, with 4767 (27.823%) articles published, followed by Peoples R China (2747 (16.033%)) articles.
