Advice for Travellers

All travellers to affected 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.

• Prevention relies on avoiding mosquito bites at all times.

A new dengue vaccine Qdenga® has been licensed in the UK.

• Guidance on the recommended use of Qdenga® vaccine is currently being drafted for the Green Book, but is not yet available.
• In the interim period, please see the JCVI guidance on the safe use of the Qdenga® vaccine

Treatment for dengue is supportive only.
