Update on dengue in Brazil
21 June 2022
The Brazilian Ministry of Health has reported the continuing spread of dengue fever in all five regions of the country. Between 1 January and 31 May 2022, 1,104,742 cases of dengue, including 504 deaths, were reported, which represents an increase of 198% in cases compared to the same period in 2021.
Dengue is an infection found in tropical and sub-tropical climates worldwide. Dengue is spread by Aedes mosquito bites and can cause a severe flu-like illness. There is no vaccine against dengue fever licensed in the UK, with treatment being 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, and bite between dawn and dusk. 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.
Information and advice for travellers on dengue fever is available on the TRAVAX (for health professionals) and fitfortravel (for the general public) websites.
