dengue hemorrhagic fever shock syndrome (DHFSS), a grave form of dengue fever characterized by shock with collapse or prostration; cold, clammy extremities; a weak, thready pulse; respiratory distress; and all of the symptoms of dengue fever. Hemorrhages, bruises, and small reddish spots indicating bleeding from skin capillaries, as well as bloody vomit, urine, and feces, may be experienced and may precede circulatory collapse. This syndrome occurs when a person with immunity to one type of dengue virus becomes infected with another serotype. Treatment includes fluid and electrolyte replacement and blood, fresh frozen plasma, or platelet transfusions as needed. Oxygen and sedatives may be administered. See also dengue fever.
