Bibliometric Analysis on Ebola Virus Disease (EVD) Research using PubMed and Google Scholar databases

\articletype Original Articles Background Ebola virus disease is a zoonotic viral disease of the Filoviridae family that is endemic to the regions of West and equatorial Africa. It is a disease that is common among primates but has affected humans in recent years. The aim of the study is to analyze the growth patterns of research on Ebola disease, synthesize the findings that have evolved from continuous research, identify research trends as well as research gaps prevailing in Ebola disease, and provide insight into future studies and research. This manuscript explores the research topics and collaborative behavior of authors in the field of Ebola virus disease. Methods Ebola virus publications from 1980-2023 were retrieved from the databases Google Scholar and PubMed using the keywords “Ebola Virus Disease,” “Ebola,” “Ebola virus,” “Ebola disease,” and “Ebola virus.” VOSviewer was used for visualization. This study focused on the dominance of keywords and collaborations among authors. Using the search strategy, 997 and 9975 studies were extracted from Google Scholar and PubMed, respectively. Results The most dominant keywords, like ‘disease outbreak’ and ‘ebola vaccines,’ showed the research trends and topics that have been analyzed and topics garnering interest in recent years. It also provides insight into research gaps present. The most contributing authors in PubMed included Feldmann Heinz, Geisbert Thomas W, Geisbert Joan B, and Marzi Andrea, while in Google Scholar, WHO was the most contributing author, with Cenat Jude Mary, Bukaka Jacqueline, and Rousseau Cecile being the most collaborated authors. The results also showed the growth patterns of research on Ebola disease. It was observed there was low output of Ebola virus publications until in 2014 when there was a sudden increase in publications. The highest output of publications occurred in 2015, and this was in correlation with the Ebola virus outbreak in 2014. Conclusion This study depicts the progress and current trends in Ebola virus research, has highlighted the role played by the various stakeholders, and has analyzed the growth patterns of research on Ebola disease.
