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.
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.
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.
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.
