The World Health Organization reports a large increase in cases of dengue fever in Timor-Leste since the start of 2022.
In January 2022, there were 1286 cases including 20 deaths. More than half of the cases were children under the age of 14 years. In all of 2021 there were 901 cases, including 11 deaths.
Dengue is an infection found in tropical and sub-tropical climates worldwide. It is spread by Aedes mosquito bites and can cause a severe flu-like illness.
There is no vaccine against dengue licensed in the UK. Treatment is supportive only.
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.
