What are the symptoms of dengue fever?

Page last updated 28 February 2019

The symptoms of dengue fever are high fever and at least two of the following:

  • Severe headache
  • Severe eye pain
  • Joint pain
  • Muscle and/or bone pain
  • Rash
  • Mild bleeding (e.g. from gums)
  • Low white blood cell count

A small proportion of cases can progress to severe dengue (sometimes called dengue haemorrhagic fever). A rapid deterioration can occur 2-5 days after onset of fever. The complications of severe dengue can lead to collapse and can be fatal.

Anyone showing symptoms of dengue should see a doctor as soon as possible.
