Brief description

Dengue fever is an acute illness due to a mosquito-borne viral infection  Dengue viral infection may be asymptomatic or present with clinical manifestations ranging from a mild fever to a life-threatening shock syndrome.  Only clinical evident infection is covered by the SOP.

Confirming the diagnosis

The diagnosis requires both (i) confirmation by serological testing or by detection of viral nucleic acid or viral antigen in serum and (ii) clinically manifest disease consistent with dengue fever and with the laboratory results.  If there is a confirmed history of dengue fever and the condition is no longer present the diagnosis made should be dengue fever – resolved, or alternatively, No Incapacity Found.

The relevant medical specialist is an infectious diseases physician.

Additional diagnoses covered by SOP
  • Dengue haemorrhagic fever
Conditions not covered by SOP
  • Asymptomatic dengue virus infection (serology positive for past infection but no clinical illness) - not a disease or injury.

Dengue haemorrhagic fever can occur when there is a new infection with a dengue virus and there has been a past infection (any time before, including many decades) with a different strain of the dengue virus.

Clinical onset

Clinically apparent dengue typically presents with a sudden high-grade fever (lasting for five to seven days), accompanied by headache, eye pain, vomiting, muscle and bone pain, and a transient macular rash in some cases.

Clinical worsening

The only worsening factor is for inability to obtain appropriate clinical management.  Severe disease / dengue hemorrhagic fever may result in bleeding or shock, potentially causing death if not managed appropriately.
