BACKGROUND: Dengue has emerged as a rapidly escalating health issue in low- and middle-income countries, with its burden and geographic spread increasing over the years. Malaysia, in particular, has witnessed a significant rise in dengue cases, accompanied by a spike in mortality rates. Several studies have identified various factors, primarily focusing on the 27 clinical aspects of severe dengue infection and the development of dengue-related fatalities. Expanding on this focus, this study aims to identify the demographic, clinical, and environmental factors contributing to dengue mortality, providing a more comprehensive understanding of the variables influencing dengue-related fatalities.
METHODS: This study utilized a 1:2 case-control design, analyzing data from the E-dengue system database and medical records from January 2015 to December 2022, involving 219 participants (73 dengue fatalities as cases and 146 recovered patients as controls). Dengue deaths were confirmed by the Penang State Mortality Review Committee, and controls were randomly selected from laboratory-confirmed dengue cases. Statistical analyses were performed using SPSS software, including descriptive statistics, chi-square tests, and multivariable logistic regression to identify predictors of dengue mortality, with variables included in the multivariable model if p
