Argentina reports continuing widespread transmission of dengue across the country. From 1 January 2023 to 2 December 2023, there have been 124 804 locally-acquired cases of dengue, which is almost half of the total number of cases reported in the past 25 years.
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.
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.
A new dengue vaccine Qdenga® has been licensed in the UK and is awaiting JCVI recommendations for use.
Travellers developing a fever during or on return from travel are advised to seek medical attention as soon as possible.
