Differential Diagnoses

Hepatitis
Tick-Borne Diseases, Rocky Mountain Spotted Fever
Malaria
Yellow Fever
Meningitis
Pediatrics, Bacteremia and Sepsis
Pediatrics, Meningitis and Encephalitis

Other Problems to Be Considered

Leptospirosis
Rickettsioses
River viruses
Scrub typhus
Typhoid
Viral infections (eg, influenza, chikungunya, Mayaro fever, Rift Valley fever, West Nile, Sindbis, and Ross River)

Workup

Laboratory Studies

  • Isolation of virus in serum and detection of immunoglobulins (IgM and IgG) by enzyme-linked immunosorbent assay (ELISA) antibody capture, monoclonal antibody, or hemagglutination
  • Complete blood count
    • Hemoconcentration (hematocrit increased 20%)
    • Thrombocytopenia (platelet count <100 x 109/L)
    • Leukopenia
  • Chemistry panel
    • Electrolyte imbalances
    • Acidemia
    • Elevated BUN
  • Liver function tests
    • Elevated transaminases
    • Hypoproteinemia
  • Guaiac test for occult blood in stool

  • Signs of early coagulopathy may be as subtle as a...

    Signs of early coagulopathy may be as subtle as a guaiac test positive for occult blood in the stool. This test should be performed on all patients in whom dengue virus infection is suspected.

    Signs of early coagulopathy may be as subtle as a guaiac test positive for occult blood in the stool. This test should be performed on all patients in whom dengue virus infection is suspected.

  • DIC panel, as indicated

Imaging Studies

  • Chest radiography
    • Bronchopneumonia
    • Pleural effusion
  • Head CT scan without contrast
    • For altered level of consciousness
    • Intracranial bleeding
    • Cerebral edema

Other Tests

  • Electrocardiography
    • Nonspecific changes may be effects of fever, electrolyte disturbances, tachycardia, or medications.
    • Usefulness of these changes as a marker of cardiac involvement is unclear.
