Dengue fever is a viral infection transmitted by mosquitoes, especially in tropical and subtropical regions. It can cause high fever, severe headaches, joint pain, and in some cases, serious complications such as dengue hemorrhagic fever.

A vaccine is available in the UK that provides protection against dengue fever.

Vaccination is recommended for travellers aged 4 and above who are visiting areas where dengue is common and where they are at increased risk of infection, such as during outbreaks or prolonged stays.

The areas with the highest risk of dengue fever include:

Southeast Asia
Central and South America
The Caribbean
Sub-Saharan Africa
The Indian subcontinent
