A Bibliometric Analysis on Dengue Outbreaks in Tropical and Sub-Tropical Climates Worldwide Since 1950

Abstract

Severe dengue outbreaks (DOs) affect the majority of Asian and Latin American countries. Whether all DOs always occurred in sub-tropical and tropical areas (STTA) has not been verified. We downloaded abstracts by searching keywords “dengue (MeSH Major Topic)” from Pubmed Central since 1950, including three collections: country names in abstracts (CNA), no abstracts (WA), and no country names in abstracts (Non-CNA). Visualizations were created to present the DOs across countries/areas in STTA. The percentages of mentioned country names and authors’ countries in STTA were computed on the CNA and Non-CNA bases. The social network analysis was applied to highlight the most cited articles and countries. We found that (1) three collections are 3427 (25.48%), 3137 (23.33%), and 6884 (51.19%) in CNA, WA, and Non-CNA, respectively; (2) the percentages of 94.3% and 79.9% were found in the CNA and Non-CNA groups; (3) the most mentioned country in abstracts were India, Thailand, and Brazil; (4) most authors in the Non-CNA collections were from the United States, Brazil, and China; (5) the most cited article (PMID = 23563266) authored by Bhatt et al. had 2604 citations since 2013. Our findings provide in-depth insights into the DO knowledge. The research approaches are recommended for authors in research on other infectious diseases in the future, not just limited to the DO topic.

Dengue in India: An Overview

“…Severe dengue was identified first during the dengue epidemics in Philippines, and Thailand in the 1950s. 1 Severe dengue fever now affects the majority of Asian, and the Latin American countries and it is the leading cause of hospitalization, and death among the children, and adults in above mentioned regions. Dengue is caused by a virus of the flavi-viridae family and there are four distinct, but very closely related; serotypes of virus which cause dengue (DENV-1, DENV-2, DENV-3 and DENV-4).…”

Research features between Urology and Nephrology authors in articles regarding UTI related to CKD, HD, PD, and renal transplantation

“…Step 1: Cluster analysis was performed using SNA [ 37 – 39 ] and Pajek software [ 45 ] for the keyword plus in UN departments and drawing them on Sankey diagrams. [ 46 , 47 ]…”

“…Step 1: Cluster analysis was performed using SNA [37][38][39] and Pajek software [45] for the keyword plus in UN departments and drawing them on Sankey diagrams. [46,47] Step 2: A comparison of differences in RFs was made on the forest plot.…”

“…By using social network analysis (SNA) [ 37 – 39 ] to replace MeSH terms [ 25 – 27 ] with keyword plus, the RFs between UN authors can be compared using forest plots. [ 25 , 36 ]…”

Human FcγRIIIa activation on splenic macrophages drives the in vivo pathogenesis of dengue disease

“…Dengue virus (DENV) poses a significant threat to global public health, causing an estimated 50 to 100 million new infections annually 1 . Although DENV infection often manifests as an inapparent or mildly symptomatic disease, approximately 10% of DENV-infected patients experience more severe forms of symptomatic disease, which include dengue hemorrhagic fever (DHF) and dengue shock syndrome (DSS), characterized by persistent high-grade fever, thrombocytopenia, and vascular leakage, resulting in significant morbidity and mortality 2,3 .…”
