Global trends in dengue research in veterinary medicine (2019–2024): A bibliometric analysis of scientific output, collaborations, and thematic shifts

Background and Aim: Dengue is a significant mosquito-borne viral disease with increasing public health relevance, particularly in tropical and subtropical regions. Although it primarily affects humans, veterinary research plays a crucial role in understanding disease dynamics, particularly through the use of animal models and vector control strategies. This study aimed to analyze global research trends on dengue within the field of veterinary medicine between 2019 and 2024, identifying patterns in productivity, collaboration, and emerging thematic priorities.

Materials and Methods: A bibliometric analysis was conducted using Scopus-indexed publications retrieved on December 15, 2024. The search included terms related to dengue and Aedes species within the veterinary subject area. Data were analyzed using SciVal for metrics and collaboration patterns and RStudio for statistical summaries and visua-lizations. Inclusion criteria encompassed peer-reviewed studies on dengue relevant to veterinary contexts published between 2019 and 2024.

Results: A total of 742 publications were identified across 67 journals, including 652 articles and 60 reviews. Annual output showed a 3.01% decline, with an average document age of 2.56 years and 9.0 citations per article. International collaboration was evident in 41.51% of publications, with Brazil, Argentina, and Australia emerging as key contributors. Thematic evolution demonstrated a shift from basic entomological studies (2019–2020) to applied control strategies, including Wolbachia-based mosquito interventions and citizen surveillance (2021–2022). The most prolific institutions were Fundação Oswaldo Cruz (Brazil) and the University of Florida (USA), while the journal Parasites and Vectors had the highest publication volume.

Conclusion: This bibliometric review highlights the growing interdisciplinary nature of dengue research in veterinary medicine and the pivotal role of international collaboration. The observed decline in publication rate underscores the need to reinvigorate research efforts. The findings advocate for a One Health approach integrating veterinary, ecological, and public health disciplines to address vector-borne diseases. Future efforts should focus on enhancing global partnerships, standardizing animal models, and supporting innovative vector control strategies to mitigate the burden of dengue.
