Seroprevalence Of Dengue Infection In A Tertiary Care Hospital From Southern Rajasthan

Key Points

The study found a 11.23% seroprevalence of dengue among febrile patients, indicating a significant public health concern.
Out of 260 seropositive cases, males made up 55% and the majority were aged 21–30 years, signifying higher vulnerability in this demographic.
Blood samples were analyzed using rapid immunochromatographic assays for NS1 antigen and IgM/IgG antibodies, revealing diverse serological results.
Prompt deployment of rapid diagnostics is essential for early dengue identification, emphasizing the need for effective vector control measures.

Abstract

Introduction: Dengue continues to be a significant vector-borne viral infection in tropical and subtropical regions, accounting for considerable morbidity and mortality. With repeated outbreaks in India, particularly among males and young adults, prompt diagnosis and surveillance are vital. Materials 25%), followed by 11–20 years (54; 20.8%). Serological results: NS1 antigen only in 110 (42.4%), IgM only in 108 (41.5%), IgG only in 5 (1.9%), NS1 + IgM in 25 (9.6%), NS1 + IgG in 2 (0.8%), IgM + IgG in 5 (1.9%), and NS1 + IgM + IgG in 5 (1.9%). Conclusions: The 11.23% seroprevalence underscores dengue’s public health impact in Central India, disproportionately affecting males and young adults. Deployment of NS1- and IgM-based rapid diagnostics is crucial for early case identification. Continued seroepidemiological surveillance and vector control measures are warranted to mitigate dengue-related morbidity and mortality
