Dengue, epidemic, retrospective data, trend analysis


Background: This study aims to identify patient number trends in three tertiary care hospitals affiliated with Rawalpindi Medical University by conducting a secondary data analysis of past hospital records.

Methods: A retrospective study, spanning from 2013 to 2022, was undertaken in three tertiary care hospitals (Holy Family Hospital, District Head Quarters Hospital, and Benazir Bhutto Hospital) affiliated with Rawalpindi Medical University. The analysis included data on outpatient department (OPD) visits, admission rates, confirmed cases, morbidity and mortality variables related to Dengue Hemorrhagic Fever (DHF) and Dengue Shock Syndrome (DSS), fatalities, expiries %, and the predominant Dengue virus genotype. Statistical analysis utilized SPSS version 25.0.

Results: The records encompassed 299,101 OPD patients in the three allied hospitals. Over the past decade, an epidemic occurred in 2019, witnessing a surge—87,680 OPD cases, 14,879 admissions, and 11,942 confirmed cases. A second peak in the current year saw 32,940 cases. Maximum fatalities occurred in 2021 (0.68%), followed by 2013 (0.57%). Dominant Dengue serotype was DEN-2, except in 2022, which showed both DEN-1 (40%) and DEN-2 (60%).

Conclusion: Trend analysis of dengue cases from 2013 to 2022 revealed a peak in 2019, followed by the current year (2022), indicating a significant increase. The rise during the current epidemic, coupled with a new serotype (DEN-1), may be linked to human migration due to recent floods, population displacement, and virus evolution, evident in increased cases with different serotypes.
