Global a Decade of Dengue Fever and Aedes Mosquitoes Research Analysis on Trends and Hotspots in Dengue Transmission Risk

Abstract

A comprehensive review was conducted of international studies on dengue fever and its transmission vector, Aedes mosquitoes, spanning the past decade. Through the analysis of research trends and the visualization of key content, this review facilitated a swift comprehension of the research landscape in this field for future researchers. Articles published from 2014 to 2023 in the Web of Science Core Collection, pertaining to dengue fever and Aedes mosquitoes, were aggregated for analysis. VOSviewer software was employed to construct visualization network maps, depicting keyword co-occurrence, country collaboration, institution collaboration and the source journal within these two research domains; then, used Citespace 6.4.R1 software and R packages to summarize bursts of keyword citations and the h-index of journals. Furthermore, Prism software was utilized to generate bar charts illustrating the number of articles published annually in each field over the decade. Following a thorough literature retrieval and screening process, a total of 17,009 articles were identified in the “dengue fever” research area, with 2,010 keywords, 110 countries, 957 institutions and 272 journals meeting the inclusion criteria. Similarly, in the “Aedes mosquitoes” research area, 12,518 articles were found, with 1,745 keywords, 107 countries, 685 institutions and 192 journals qualifying for the study. Notably, both “dengue”, “Aedes aegypti” and “Aedes albopictus” ranked among the top ten most frequent keywords in their respective fields, the top three countries in terms of the number of published articles in the two fields were exactly the same, four research institutions featured prominently in the top ten for the number of articles published in each field and a considerable number of journals have a high overlap in focus between the two fields. Additionally, Avg. citations and h-index were not proportional to the number of articles. Dengue fever has attracted considerable international attention, and the research interest in its transmission vector, Aedes mosquitoes, follows a similar trend, highlighting the pivotal role of Aedes mosquitoes in the transmission of dengue fever. Between 2014 and 2023, the research progress of the two fields influenced each other, and their research progress was also caused by a combination of various factors. Exploring the hidden mysteries within can help relevant researchers better understand the dynamics of the field and filter useful information.
