Introduction: Dengue fever is a mosquito-borne arboviral (arthropod-borne virus) disease which is of global concern. This fever is a benign syndrome caused by an arthropod-borne virus and is characterized by Biphasic fever, myalgia, arthralgia, rash, leukopenia, and lymphadenopathy. Aim of the study: This study aimed to evaluate the clinical and laboratory profile of dengue fever in children less than 15 years old admitted to an urban hospital. Methods: This retrospective study was conducted in the Department of Paediatrics of Anwer Khan Modern Medical College Hospital (AKMMCH), Dhaka, Bangladesh during the period from 4 April 2019 to 9 September 2019. They have followed up on the symptoms, platelet count and management of the patients. Data were analysed by using MS-Excel-2016. Result: In total 98 patients from both groups completed the study. In our study, we found a maximum of 54.08% were male, more than half 53(54.08%) patients were below five years of age, about 95(96.94%) of the patients had a fever. Maximum patients, 81(82.65%), were managed by I/V fluid, more than 72(73.47%) of the patients were managed by paracetamol. Others by antibiotics 16(16.33%), platelet transfusion 14(14.29%) and blood transfusion 12(12.24%). Other management also includes plasma, & dopamine. Conclusion: These study children about 0-15 years of age more commonly suffer from dengue fever. As the vaccine is not available in Bangladesh, these patients need a timely diagnosis and critical monitoring during the disease course to prevent severity and mortality.
