 Material and Methods: This cross-sectional study was done among admitted children with dengue infection in Dhaka Shishu (Children) Hospital from July 2018 to October 2018. The diagnosis of dengue fever (DF), dengue hemorrhagic fever (DHF), and dengue shock syndrome (DSS) were established according to the World Health Organization (WHO) classification criteria.

Majority of the cases (74.5%) were less than 10 years of age, 60.8% were male, 39.2% were female, and 88.23% of patients came from urban areas. Classic DF was found in 74.5% of patients, while 25.49% of patients DHF, and 11.7% DSS. Fever was the most common (72.55%) symptom followed by headache, vomiting and myalgia. Hemorrhagic manifestations found in 21.57% of cases. The most common complications were hepatic dysfunction (47.09%) followed by renal impairment, encephalopathy, multi-organ failure, and ARDS.
