Dengue virus, a mosquito-borne flavivirus, is the causative agent, currently one of the most significant emerging disease challenges to global health. The dengue virus are single-stranded positive-sense RNA viruses with a genome of about 11000 bases that codes for three structural proteins, C(core protein), M (membrane protein), E (envelope protein); 7 nonstructural proteins, NS1, NS2a, NS2b, NS3, NS4a, NS4b, NS5; and short non-coding regions on the 5' and 3' ends. This was a case control study design in which 201 cases of dengue fever admitted in the pediatric emergency ward, were enrolled. After taking written informed consent, data were collected in a predesigned semi structured questionnaire regarding Socio-Demographic profile, medical history, clinical and hematological profile and outcome. 8(4%) of cases had positive family h/o dengue fever, 3(1.5%) cases had positive past h/o dengue fever and 8(4%) cases had positive h/o travel to dengue endemic areas. 201(100%) cases had fever, 94(46.8%) had persistent vomiting,91(45.3%) had anorexia,78(38.8%) had abdominal pain, 59(29.4%) had headache, 30(14.9%) had rashes, 16 (8%) had facial puffiness, 14(7%) had convulsions and 12(6%) had abdominal distension.
