Dengue among Patients Visiting Department of Medicine in a Secondary Care Centre: A Descriptive Cross-sectional Study

Abstract

Introduction: Dengue, caused by the dengue virus, has a wide range of clinical features, including fever, body ache, lethargy, nausea, and vomiting. Blood-based biomarkers in patients with dengue virus infection reflect a variety of clinical spectrums, from bleeding manifestations to liver abnormalities, and can serve as an essential tool for clinicians. This study aimed to determine the prevalence of dengue among patients visiting the Outpatient Department in a secondary care centre. Methods: A descriptive cross-sectional study was conducted among patients visiting the Outpatient Department from 16 May 2022 to 15 November 2022. Ethical approval was obtained from the Institutional Review Committee (Reference number: 20790202). The socio-demographic details and biochemical and haematological findings of dengue virus-infected patients diagnosed with rapid diagnostic tests were collected. Convenience sampling was done. Point estimate and 95% Confidence Interval were calculated. Results: Out of 706 individuals, the prevalence of dengue was 83 (11.76%) (9.38-14.14, 95% Confidence Interval). The median age of dengue virus-infected patients was 40 years, and the majority were males 54 (65.06%). Conclusions: The prevalence of dengue was found to be lower than in other studies done in similar settings.
