Global research trends at the intersection of climate change and parasitic diseases: a systematic bibliometric research (2000–2025)

BackgroundClimate change is increasingly recognized as a critical driver affecting the transmission and distribution of parasitic diseases. However, a comprehensive synthesis of the global research landscape in this interdisciplinary field is lacking. This study provides an integrated analysis of research trends, collaborative networks, and emerging themes from 2000 to 2025.MethodsWe retrieved relevant articles and reviews from Web of Science and Scopus, analyzing 7,303 publications using visualization and statistical tools. Bibliometric analysis included publication trends, contributions by countries/institutions, author networks, journal profiles, and keyword evolution.ResultsAnnual publications grew steadily at 13.1%. The United States led in output (5,085 papers) and citations (55,533), with strong international collaboration (40.5% cooperation rate). Key journals included Veterinary Parasitology and high-impact journals such as Science and Nature. Authors clustered into five major collaborative groups, with Poulin R. and Johnson P. T. J. as the most productive and influential researchers, respectively. Keyword analysis identified core themes including zoonoses, climate epidemiology, One Health, and specific diseases like malaria and schistosomiasis. Emerging keywords such as “One Health” and “Surveillance” showed annual growth exceeding 200%.ConclusionBy integrating advanced bibliometric analysis, this study provides new insights. Specifically, research on climate change and parasitic diseases is evolving toward interdisciplinary and systems-oriented approaches. Future efforts should prioritize predictive modeling, global health governance, and integrating biodiversity conservation with disease control to mitigate climate-related health risks.
