Symptoms of dengue

Symptoms of dengue usually develop suddenly 4 to 10 days after becoming infected.

Symptoms can include:

  • a high temperature (fever), which can reach 40C (104F) or higher
  • severe headaches
  • pain behind the eyes
  • muscle and joint pain
  • feeling or being sick
  • a widespread red rash
  • loss of appetite

The symptoms normally pass in about a week, although you may feel tired and slightly unwell for several weeks afterwards.

In rare cases severe dengue can develop after the initial symptoms.

When to get medical advice

See your GP or call emergency and urgent care-services if you develop a fever or flu-like symptoms within two weeks of returning from an area where the dengue virus is found.

Remember to tell them whereyou've been travelling.

Go to a local doctor or hospital if you develop symptoms while travelling or living in an area where dengue is common.

There's little a doctor can do to help you recover, but it's important to get a proper diagnosis in case there's another cause of your symptoms.

You may need a blood test to confirm that you have dengue.
