Introduction: Dengue epidemics are known to have occurred over the last three centuries in tropical, subtropical and temperate areas of the world. Annually a 100 million cases of Dengue fever and half a million cases of dengue hemorrhagic fever (DHF) occur in the world with a case fatality in Asian countries of 0.5%–3.5%. Objective: To assess the various factors in pediatric to severe dengue infection. Methods: A hospital-based Retrospective study was conducted at Department Of Paediatric, Mugda Medical College Hospital, Dhaka, Bangladesh from October to December 2023. Number of patients included in the study was 50. In children with high degree clinical suspicion of Dengue infection NS 1 antigen (who came within first 48 hours of fever) and/or Dengue antibody IgM, IgG (who came after five days of fever) were performed. Positive Dengue cases were taken written informed consent & interviewed on the risk factors of Dengue infection. Data related to patients demography, risk factors, clinical presentation, pattern of Dengue infection and outcome were documented on the pre-structured questionnaire. Results: The study was enrolled 100 patients of suspected dengue fever of whom 50 (50.0%) were serologically confirmed to have dengue infection. 30 (60%) patients were males and 20 (40%) were females. 38 (76%) patients had classic dengue fever while 12 (24%) fulfilled the criteria of dengue hemorrhagic fever. Of those patients with dengue hemorrhagic fever, 6 patients had developed dengue shock syndrome. Among the study 44 (88%) from urban and 6 (12%) rural area patients. All cases and is the most common symptom followed by headache, myalgia, vomiting etc. Hemorrhagic manifestations were seen that included petechiae, ecchymosis, gum bleeding, hematuria, malena, hematemesis and epistaxis. Most common complicationswere hepatic dysfunction, renal failure, multi organ failure, encephalopathy and ARDS. Among 50 suspected dengue cases 38 (76.0%) cases were serologically dengue positive. Among the 38 serologically dengue positive patients 17 (44.7%) were NS1 antigen positive, 13 (34.2%) IgM antibodies and 8(21.0%) both IgM and IgG antibodies positive. The distribution of the serologically dengue positive patients out of 50 clinically suspected cases. Conclusion: Dengue is one amongst the key causes of dedifferentiated fever. It presents as an extremely broad wellness and is hardly recognized as a clinical entity by primary health care physicians. This study highlights the practician the importance of break bone fever to clinicians within the areas of medical specialty, manifestations, complications and outcome of the wellness
