According to the Vietnamese Ministry of Health official newspaper there have been 60 000 cases of dengue fever in 2022, as of 16 June. There have also been 36 deaths from dengue fever, which is more common in the south of Vietnam.
Dengue fever 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.
