Dengue fever has various levels of severity, from mild disease to severe hemorrhagic complications and shock. Dengue is endemic world-wide and has been found in the United States. The mortality from dengue fever can be as high as 15-20%, with nearly 22,000 deaths annually, most of them children (Reddy, 2013). There is no reliable way to immediately predict which children presenting with a fever during a Dengue fever outbreak will progress to more severe disease. Some children with dengue fever will improve with limited clinical interventions, but others require intensive therapy. Limited healthcare resources in developing countries make decisions on treatment or disposition difficult as many children and poor clinical decision increase morbidity and mortality. In more developed countries such as the United States, early identification of patients with dengue fever has the potential to identify children who may benefit from early interventions. Identifying those patients is the first step in exploring early therapies to effect mortality. Previous research has demonstrated that intrathoracic/ peritoneal fluid and gallbladder wall thickening is associated with worsening of the clinical prognosis for hospitalized patients with dengue fever (Michels, 2013). We will explore earlier presentations in the emergency department and outpatient department.
