Dengue fever is a mosquito-borne viral infection common in tropical and subtropical regions. Symptoms can range from fever and muscle aches to severe complications that may require hospital care. Cases continue to rise globally, and outbreaks are increasingly reported in popular tourist destinations.

Northfields Travel Clinic offers Qdenga®, the only available Dengue vaccine currently used for travellers in the UK.
Dengue is widespread in:
Southeast Asia (Thailand, Indonesia, Vietnam, Malaysia, Philippines)
South & Central America (Brazil, Peru, Colombia, Costa Rica)
Caribbean islands (Dominican Republic, Jamaica, Puerto Rico)
Pacific islands (Fiji, Tahiti)
Parts of Africa
Indian subcontinent (India, Sri Lanka, Maldives)
Risk is highest:
During rainy seasons
In urban and semi-urban areas
When mosquitoes are most active (daytime, especially mornings and afternoons)
Aedes mosquitoes — the same ones that spread Zika and Chikungunya — are aggressive daytime biters.
Most infections cause flu-like symptoms, but severe Dengue can cause:
Severe abdominal pain
Persistent vomiting
Internal bleeding
Shock
Hospitalisation
There is no specific antiviral treatment, making prevention and vaccination the most important tools for travellers.
Vaccination is recommended for:
Travellers spending long periods in Dengue-endemic countries
Those making repeated trips to high-risk regions
Individuals staying with local families
Backpackers or adventure travellers
Healthcare or humanitarian workers in affected regions
Those visiting during peak outbreak seasons
Short holidays in low-risk areas may not require vaccination — your travel specialist pharmacist will guide you based on your itinerary.
We offer the Qdenga® vaccine for eligible individuals aged 4 years and above.
Two doses
Given 3 months apart
No booster currently required
Around 80–82% protection against symptomatic Dengue

This vaccine may not be suitable if you:
Are immunocompromised
Have certain medical conditions
Are pregnant or breastfeeding (requires risk assessment)
Have a history of severe allergic reactions to vaccines
Your clinician will assess eligibility during your consultation.
Even with vaccination, you should continue mosquito bite avoidance:
Use 50% DEET or equivalent repellent
Wear long sleeves and trousers during the day
Stay in air-conditioned or screened accommodation
Use mosquito coils or plug-in vaporisers
Remove standing water near where you stay
Avoid heavily infested outdoor areas during outbreaks
These precautions also reduce risk of Zika and Chikungunya.

Protect yourself from Dengue, reduce the risk of hospitalisation and travel with confidence.
No — the 2-dose course is required for optimal protection.
Ideally 3 months before travel to allow time for both doses.
If not possible, you can still start the course and complete it later.
