Advice for Travellers

Dengue is an infection found in tropical and sub-tropical climates worldwide.

All travellers to endemic regions are potentially at risk of dengue fever and should be aware of this infection.

Aedes mosquitoes are particularly persistent and aggressive. They bite between dawn and dusk.

A new dengue vaccine Qdenga® has been licensed in the UK and is awaiting JCVI recommendations for use.

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