AbstractThe rising number of immunocompromised people has increased concerns about fungal infections as a severe public health issue. Invasive pulmonary fungal infections (IPFIs) are prevalent and often fatal, particularly for those with weakened immune systems. Understanding IPFIs is crucial. The work aims to offer a concise overview of the field's characteristics, main research areas, development paths, and trends. This study searched the Web of Science Core Collection on June 5, 2024, collecting relevant academic works from 2003 to 2023. Analysis was conducted using CiteSpace, VOSviewer, Bibliometrix Package in R, Microsoft Excel 2019, and Scimago Graphica. The study indicated that the USA, the University of Manchester, and Denning DW led in productivity and impact, while the Journal of Fungi topped the list in terms of publication volume and citations. High-frequency terms include "fungal infection," "invasive," "diagnosis," and "epidemiology." Keyword and trend analysis identified "influenza," "COVID-19," "invasive pulmonary aspergillosis," and "metagenomic next-generation sequencing" as emerging research areas. Over the last 2 decades, research on IPFI has surged, with topics becoming more profound. These insights offer key guidance on current trends, gaps, and the trajectory of IPFI studies.Copyright © 2024 the Author(s). Published by Wolters Kluwer Health, Inc.
