Dengue Fever (also known as break bone fever) is a viral illness, which is transmitted by the Aedes mosquito, which tend to be more active during the day. Most commonly found throughout the tropics and subtropics, Dengue Fever is endemic in approximately 100 countries. It is estimated that there are currently 50 million cases of the disease reported each year. Symptoms include a sudden onset of high fever, skin sensitivity, joint and muscle pains, headache and rashes.

Seek professional medical advice prior to visiting a high risk area. There is no vaccine available for Dengue Fever so protection against being bitten is vital, see our section on prevention.

Travellers should alert their GP of any fever illness occurring after leaving an endemic area.
