Dengue Fever

What is dengue fever?

Dengue fever is widespread in many parts of the world, and is spread by mosquitoes carrying the dengue virus. It usually passes without complications, but in rare cases, it can be fatal.

The symptoms of dengue fever will usually develop around 4-10 days after being infected with the virus. These symptoms are worst within the first week, and include:

  • a fever, which may exceed 40C (104F)
  •  a red skin rash
  • muscle pain, joint pain
  • headache and pain around the eyes
  •  lack of appetite
  •  nausea and/or vomiting

After the initial stage passes, symptoms will go away but you may feel a lingering fatigue or general unwellness for some weeks.

Affected areas
All over Asia and S. America


Dengue fever is contracted through mosquito bites from insects infected with the virus. It is most common in Africa, southeast Asia, Australia, the Caribbean, Central America, India, the Pacific Islands, and South America. The vaccine for dengue fever is not widely available, and the best method of prevention is protecting against mosquito bites.

What is severe dengue?

This is a more serious and possibly life-threatening case of dengue fever. It is rare for travelers to contract this, and is usually found in those who have already been infected with dengue in the past. Symptoms include vomiting blood, bleeding under the skin or from the gums, and a swollen, painful belly.

When should I see a doctor for treatment of dengue?

If you have been to a country where dengue is common within the past month, and are experiencing fever, flu-like symptoms or are simply feeling unwell, it is important that you see a doctor.

How is dengue fever treated?

There is no cure for dengue fever. The method of treatment is to manage symptoms until the infection clears up. A proper diagnosis is nonetheless important, in order to monitor symptoms and ensure that there is no other cause of your illness.
