Dengue Hemorrhagic Fever Dengue Shock Syndrome
Key Points
Dengue hemorrhagic fever occurs primarily in children < 10 years living in areas where dengue is endemic and requires prior infection with the dengue virus. Dengue hemorrhagic fever may initially resemble classic dengue fever, but certain findings (eg, severe abdominal pain and tenderness, persistent vomiting, hematemesis, epistaxis, melena) indicate possible progression to severe dengue. Circulatory collapse and multiorgan failure, called dengue shock syndrome, may develop rapidly 2 to 6 days after onset. Diagnose based on specific clinical and laboratory criteria. Maintaining euvolemia is crucial.
