Advice for Travellers 

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

All travellers to endemic regions are potentially at risk of dengue fever and should be aware of this infection. Prevention relies on avoiding mosquito bites at all times.

Travellers developing a fever during or on return from travel are advised to seek medical attention as soon as possible.
