What is it?

  • A viral disease causing sudden high fever, joint and muscle aches, low back pain, headache and skin rash.
  • Symptoms usually last 4 to 7 days.
  • The severe form called dengue hemorrhagic fever, usually occurs in those who have had previous infections with another strain, and does not usually affect travellers.
  • Complications of shock, possible death especially in children, and those experiencing a second infection.

How is it spread?

  • Bite of the Aedes mosquito that feeds in the daytime.
  • This mosquito lives in urban and rural areas throughout the tropics.
  • Breeds in any small collections of standing water (old cans, tires, etc.)


  • Avoid day-biting mosquitoes.
  • Use insect repellent with DEET.
  • Insect repellents should be in lotion form (as opposed to aerosol sprays) and should contain at least 30% DEET (N,N-diethylm-toluamide) for adult use.
  • The American Academy of Paediatrics recommends that repellents used on children contain no more that 10% DEET.


  • Supportive measures including rehydration.
  • Aspirin is contraindicated because of its hemorrhagic potential.

Where is it found?

  • Africa
  • Latin America
  • Asia
  • Caribbean
  • Pacific Islands
