Overview | Symptoms | Treatment | Prevention

Alternative names:

Hemorrhagic dengue; Dengue shock syndrome; Philippine hemorrhagic fever; Thai hemorrhagic fever; Singapore hemorrhagic fever

Symptoms

Early symptoms of Dengue hemorrhagic fever are similar to those of Dengue fever, but after several days the patient becomes irritable, restless, and sweaty followed by a shock-like state.

Bleeding may appear as pinpoint spots of blood on the skin (petechiae) and larger patches of blood under the skin (ecchymoses). Bleeding may occur from minor injuries. Death generally occurs from shock. If the patient survives, recovery begins after a one-day crisis period.

Early symptoms:

Acute phase symptoms:
  • Shock-like state
    • Sweaty (diaphoretic)
    • Cold clammy extremities
  • Restlessness followed by:
    • Worsening of earlier symptoms
    • Petechiae
    • Ecchymosis
    • Generalized rash

Signs and Tests

Physical examination may show:

Tests:
  • High hematocrit
  • Low platelet count
  • Electrolytes
  • Coagulation studies
  • High liver enzymes
  • Blood gas to check oxygen content of blood
  • Tourniquet test (tourniquet causes petechiae below the tourniquet)
  • X-ray of the chest may demonstrate pleural effusion
  • Serologic studies that demonstrate antibodies to Dengue viruses
  • Acute and convalescent serum (increase in titer to Dengue antigen)
