In this week’s update, we present the current focus of the COVID-19 literature, based on publications registered in PubMed as published during the past three weeks (September 28th to October 18th). There were 527 keywords that occurred in five or more manuscripts. These divided into five main clusters. To create the map, we used the LinLog method. The minimum cluster size was set to 10.

To open the map directly in VOSviewer, please use the Keyword co-occurrence MAP and NET files from October 19th, available through the Open Science Foundation (OSF) repository:
