Advice for Travellers

Dengue is an infection spread by mosquito bites that can cause a severe flu-like illness.

If you are travelling to an affected region, you are potentially at risk of dengue fever and should be aware of this infection.

If you develop a high temperature (fever) either during or after travelling to an affected area, you should seek medical advice as soon as possible and give details of your recent travel history.
