Knowledge mapping of childhood infectious mononucleosis: a bibliometric analysis for the twenty-first century

The incidence of infectious mononucleosis (IM) has increased in recent years, particularly in the pediatric population, and there are currently no specific drugs available, posing a threat to the lives and health of children worldwide. Although some results have been published, there is a lack of systematic review and summarization of current research.

Based on screening criteria, literature on IM in children from 2000 to 2023 was retrieved from the Web of Science Core Collection. The included literature's indicators (country, institution, journal, author, keywords, and references) were analyzed and visualized using Citespace, VOSviewer software, and the Bibliometrix program package.

A total of 538 eligible publications were included in this study. The number of publications has been on an upward trend during this century, with great potential for future growth. The countries with the most publications are the USA and China, and Capital Medical University is the most contributing institution. Hjalgrim, Henrik and Cohen, Jeffrey, I are among the field's most influential authors and co-cited authors. Among the major journals, the JOURNAL OF MEDICAL VIROLOGY had the highest output and the JOURNAL OF INFECTIOUS DISEASES was the most frequently cited. The reference with the highest outbreak intensity was Ramagopalan, SV, LANCET NEUROLOGY, 2010. Through in-depth analysis of the keywords, we conclude that the characteristics of diagnosis and assessment of IM, the association of IM with other diseases, and interventions for IM are the current hot topics of research in the field and that the pathogenesis of IM due to EBV is a cutting-edge topic in the field. This study also analyzes the reasons for geographical research differences and proposes a new "increasing quantity-improving quality-integrating" cooperation model.

This study's hotspots and frontiers reflect the current status and trends in pediatric IM, and these findings provide important insights to guide future research and optimize therapeutic strategies. In the future, there is a need to strengthen international collaboration and cooperation, conduct RCTs with large sample sizes, and promote the development of new drugs in mechanism research.
