Dengue among Suspected Patients Admitted to Department of Medicine of a Tertiary Care Centre: A Descriptive Cross-sectional Study

Abstract

Introduction: Dengue virus incidence has been increasing trends in every year due to the expansion of the vectors Aedes aegypti and Aedes albopictus. The objective of this study was to find out the prevalence of dengue among suspected patients admitted to the department of medicine of a tertiary care centre. Methods: A descriptive cross-sectional study was conducted among patients admitted to the medicine department from 30 September 2022 to 30 December 2022 after obtaining ethical approval from the Institutional Review Committee (Reference number: 019/2022). Demographic, clinical characteristics and laboratory profiles were collected from dengue patients by using a structured questionnaire. Convenience sampling method was used. Point estimate and 95% Confidence Interval were calculated. Results: Among 500 patients, 242 (48.40%) (40.66-56.14, 95% Confidence Interval) were found to be dengue positive. The average age of the enrolled patients was 39.13±20.64 years. Most dengue fever patients were diagnosed in the category of dengue with a warning sign of 234 (96.69%). The mean hospital stay of dengue patients was 4.05±2.03 days, 229 (94.62%) of patients stayed less than 7 days before discharge. Conclusions: The prevalence of dengue among suspected patients admitted to the department of medicine is found to be higher than in other similar studies done in similar settings. Patients with clinical symptoms and laboratory findings corroborating with dengue should undergo early diagnosis and facilitate prompt treatment in individual patients.
