SOP Bulletin 157

ICD Coding
  • ICD-9-CM Codes: 061, 065.4
  • ICD-10-AM Codes: A90, A91
Brief description

Dengue fever is a febrile illness caused by infection with one of four dengue viruses and transmitted by mosquitoes.  Manifestations can range from a mild self-limiting illness to a severe life threatening condition.

Confirming the diagnosis

The diagnosis should be confirmed by serological testing or detection of viral components in serum and can be made by a treating general practitioner.  Dengue viral infection may be asymptomatic.  The SOP requires a clinical illness.

If there is a history of dengue fever but the condition is no longer present, a diagnosis of Dengue fever – resolved, or alternatively, No Incapacity Found, would apply.

The relevant medical specialist is an infectious diseases physician.

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

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

The condition typically presents with a sudden high-grade fever (≥38.5°C) which may be accompanied by headache, vomiting, muscle and joint pain, and a transient rash.  The fever generally lasts for 3 to 7 days.  Symptoms typically develop between 4 and 7 days after a bite from an infected mosquito.

Clinical worsening

The only SOP worsening factor is for inability to obtain appropriate clinical management.  There is no direct antiviral therapy available.  Treatment consists of supportive measures.
