Advice for Travellers

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

The mosquitoes which transmit dengue bite during the day, between dawn and dusk.  They are particularly persistent and aggressive.

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.
