Data Sheet 1_Historical evolution, research hotspots and emerging trends of pediatric hand, foot, and mouth disease: a bibliometric worldview since the 21st century.docx

BackgroundHand, foot, and mouth disease (HFMD) poses a significant challenge to global public health. Primarily caused by enterovirus and coxsackievirus infections, the disease has a particularly pronounced impact in the Asia-Pacific region. However, systematic analysis and discussion regarding the developmental trajectory, core research entities, current status, key research directions, and future prospects of pediatric HFMD research remain lacking.
MethodsThis study collected and analyzed papers and reviews on pediatric HFMD published between January 1, 2000, and February 1, 2025, from the Web of Science Core Collection and PubMed. Key research indicators were analyzed through bibliometric visualization, using tools including Excel, CiteSpace, VOSviewer, and BibliomeTools (an R-based tool in R-Studio).
ResultsSince the start of the 21 st century, academic publications in pediatric HFMD have steadily increased, with a cumulative total of 2,034 papers published by February 1, 2025. Global research distribution exhibits uneven patterns, with China emerging as core contributors. Specifically, Lin, Tzou-Yien from China, has published the largest number of papers, while Chang, Luan-Yin is the co-cited author with the highest citation rate. Solomon T et al.’s “Virology,” Epidemiology, Pathogenesis, and Control of Enterovirus 71” being the most cited study in the field. Research on pediatric HFMD is closely integrated with disciplines such as virology and epidemiology, forming core research themes around “HFMD,” “enterovirus 71,” and “enteroviruses.” Recent research has focused on the pathogenesis, epidemiology, novel therapeutic discoveries and vaccine development for pediatric HFMD. Looking ahead, it is essential to delve deeper into the molecular mechanisms underlying the interaction between the human HFMD virus and its host, and to develop multivalent vaccines targeting multiple serotypes.
ConclusionThis study employs bibliometric methods to visualize research in the field of pediatric hand, foot, and mouth disease, revealing trends and frontiers in this area. It will provide valuable reference for scholars seeking key research questions and potential collaborators.
