Dengue in Spain (Ibiza)

02 March 2023

The Spanish Ministry of Health has reported 2 cases of dengue following travel to the island of Ibiza.

Both cases were residents of Germany who visited Ibiza before becoming unwell. The first case visited Ibiza in the last week of August 2022 and the second visited in the second week of October 2022.

Each case was accompanied by two family members who are also suspected to have had dengue.

Dengue fever is an infection found in tropical and subtropical climates worldwide. It is spread by Aedes mosquito bites and can cause a severe flu-like illness.

During winter and early spring, risk of dengue in Spain is low as mosquitoes are less active. The risk is highest in the months of May to November.

There is no vaccine against dengue licensed in the UK. Treatment is supportive only.

Advice for Travellers

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.

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