Spectrum of Dengue Manifestations: A Cross-Sectional Study Among Adult Patients in a Teaching Hospital (100 Cases)

Open Access

Abstract

Background: Dengue fever is an emerging mosquito-borne viral infection presenting with a wide spectrum of clinical manifestations from mild febrile illness to severe life-threatening complications. Objective: To assess the clinical spectrum and demographic characteristics of adult dengue patients admitted to a teaching hospital. Methods & Materials: A cross-sectional study was conducted among 100 serologically confirmed adult dengue patients. Data on demographics, symptoms, warning signs, and complications were collected and analyzed descriptively. Results: Most patients were aged 26-35 years (40%), and males comprised 53%. Fever (90%), headache (81%), retro-orbital pain (60%), and nausea/vomiting (44%) were common. Myalgia and arthralgia occurred in 38% and 26%, respectively. Bleeding manifestations were present in 20% of cases, and severe signs such as shortness of breath (4%), altered consciousness (2%), and seizures (3%) were uncommon. Conclusion: The majority of dengue patients presented with classic symptoms, while a smaller proportion developed warning signs or severe manifestations. Early recognition and monitoring remain essential to reduce complications.
