Clinical Spectrum of Dengue in a Tertiary Care Hospital of Northern Bangladesh

Abstract

Background: Dengue is an emerging major infectious disease which causes frequent outbreaks affecting millions. The complex interplay between virus serotype, host immune response and environmental factor set a series of changes in dengue presentation over the years. Materials and method: This was a cross-sectional, observational study conducted on 100 diagnosed dengue patients attending a tertiary teaching hospital. The study participants were divided into severe and non-severe categories and compared in terms of their symptoms, severity and lab findings. Statistical analysis was done using SPSS. Result: Majority of the study participants were younger. Female participants were more than male. Apart from fever, headache was found to be the commonest symptom in general. Epistaxis and melaena were significantly higher among severe group than non-severe peers. Gastrointestinal symptoms were frequently present among both groups. Conclusion: Most of the cases of dengue patient didn’t suffer from life threatening infection but when the infection is severe, bleeding manifestation can be a predictor of the onset of critical illness.
