Background:
The World Health Organization's "2021-2030 Strategic Plan for Neglected Tropical Diseases (NTDs)" spotlights 21 NTDs, including three viral pathogens: Dengue, Rabies, and Chikungunya. These diseases, prevalent in tropical and subtropical areas, pose a global health threat driven by globalization. Comprehending their research trends and hotspots is vital. Hence, this bibliometric analysis aims to reveal the global research landscape and guide future strategies of viral NTDs.
Methods:
Data from the Science Citation Index Expanded of the Web of Science Core Collection (WoSCC) was analyzed for the period 2014-2023, focusing on publications related to Dengue, Rabies, and Chikungunya. Bibliometric analysis and visualization were carried out using VOSviewer, Bibliometrix in RStudio, and CiteSpace to generate descriptive statistics and identify latent thematic structures.
Results:
The analysis covered 13,472 publications from 184 countries/regions, involving 12,219 institutions/organizations, published across 1,673 journals by 56,733 researchers. An upward trend in annual publication output was seen from 2014 to 2021, peaking at 1,534 articles in 2021, followed by a significant drop. Bibliometric indicators were used to identify core journals, prolific authors, leading institutions, dominant countries, and emerging research themes.
Conclusion:
The study offers valuable insights and practical guidance for researchers in the domain of viral NTDs.
