Thematic analysis of COVID 19 studies in five large continents

The aim of this study is to reveal the research topics of COVID 19 in five continents on the WOS studies.

The present study is a descriptive study with a scientific approach and content analysis method and utilization of co-word analysis and social network analysis techniques. The research community is COVID 19 studies in the WOS. Bib Excel and Gephi software have been used to analyze data and VOS software to draw the intellectual structure.

Asian, European, American, African, Australian and Oceanic countries participated in 608, 391, 301, 66 and 43 studies. The SARS, MERS, and Sun keywords are the top keywords in the COVID 19 studies on five continents.

In Asian studies, "Pneumonia, Electric field, and Pneumonia", in European studies "Sun, X-rays, and SARS" and in American studies  "MERS, galaxies, and zoonosis" and in African studies "lightning protection, MERS and MERS" and in Ocean studies "MERS, risk management and MERS" have the highest degree, closeness, and betweenness centralities.

Asian researchers focus on epidemiological topics, European researchers focus on biological topics, and American researchers focus on epidemiological and genetic issues.
