Role of Ultrasound in Dengue Infection

Dengue has become a major national and international public health concern in recent years. Though for all practical purposes serology of dengue virus remains the gold standard in diagnosing the disease, ultrasound abdomen can detect early signs of the disease. Our study was performed to highlight and demonstrate ultrasound findings of dengue fever, assess efficacy USG findings, suspect and predict the progression of mild dengue fever to severe dengue fever by USG and its complications, thus helping in further management of patients with dengue fever. Total 200 patients with complaints and clinical findings pertaining to Dengue fever (dengue positive by IgM MAC ELISA) are evaluated by Toshibas Xario USG machine in our department. Mean age of presentation was-22.45 years and 15, 26 years for females and males respectively. There was significant statistical difference noted between mild and severe cases of dengue fever related to sonological variables like ascites, pleural effusion, and perinephric edema. Ultrasound abdomen is useful for early prediction of the severity of dengue fever, thus helps in triage and prevention of those cases which will further progress to dengue haemorrhagic fever or dengue shock syndrome.
