What are the symptoms of dengue fever?

Page last updated 19 June 2020

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

  • severe headache
  • pain behind the eyes
  • muscle and joint pains
  • nausea
  • vomiting
  • swollen glands
  • rash.

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.
