The long-term consequences of the infection in children, the phenomenon of post-COVID-19 syndrome, have been attracting increasing attention of the scientific community. The present study is a bibliometric analysis of publications addressing post-COVID (long COVID) complications in pediatric population over the period 2020\u20132025.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods and materials<\/jats:title>\n                    <jats:p>The analysis covers 1,292 records retrieved from Scopus and Web of Science (search date: June 2025). Records were retrieved using post-COVID condition\/long COVID terminology combined with pediatric-related keywords; therefore, the corpus includes pediatric-focused studies as well as influential general PCC publications indexed with pediatric terms and frequently cited in pediatric research. The search strategy combined post-COVID condition\/long COVID terminology with pediatric terms (child\/infant\/adolescent), applying filters for English language, publication years 2020\u20132025, and document type (articles and reviews). Data were merged and analyzed in R using bibliometrix\/Biblioshiny to describe productivity, collaboration, citations, and thematic structure.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      The retrieved corpus included 1,292 publications from 84 countries\/regions. The United States led productivity with 270 publications (20.9%), followed by the United Kingdom (114; 8.8%) and China (90; 7.0%). The most frequent author keywords included \u201cCOVID-19\u201d (\n                      <jats:italic>n<\/jats:italic>\n                      \u2009=\u2009900) and \u201clong COVID\u201d (\n                      <jats:italic>n<\/jats:italic>\n                      \u2009=\u2009818). Highly cited items predominantly consisted of general or mixed-age PCC frameworks, indicating that foundational long COVID literature substantially shapes citation patterns within pediatric-tagged publications. Thematic mapping showed symptom-focused clusters as dominant, while MIS-C and cognitive impairment were less prominent in author-keyword frequency and thematic clustering within the retrieved dataset.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>The
