Introduction
Dengue fever is a viral infection transmitted by mosquitoes, primarily the Aedes aegypti species. It is prevalent in tropical and subtropical regions, making it a significant concern for travellers from the UK, particularly those visiting Southeast Asia, the Caribbean, and parts of South America. As the world becomes more interconnected, understanding the risks associated with dengue fever and the available preventive measures, including vaccination, is essential for safe travel. At Edinburgh Travel Clinic, we are committed to providing you with the latest information and vaccination options to ensure your health and safety while travelling.
Understanding Dengue Fever
What is Dengue Fever?
Dengue fever is caused by the dengue virus, which has four distinct serotypes. The disease is characterised by high fever, severe headaches, pain behind the eyes, joint and muscle pain, rash, and mild bleeding. In some cases, dengue can progress to severe dengue, which can be life-threatening and requires immediate medical attention. The symptoms typically appear 4 to 10 days after being bitten by an infected mosquito, and while most cases are mild, the potential for severe illness makes awareness and prevention critical.
How is Dengue Transmitted?
Dengue is primarily transmitted through the bite of an infected Aedes mosquito, which is most active during the day. The virus can also be transmitted from mother to child during pregnancy or breastfeeding, although this is less common. Understanding the transmission methods is vital for travellers, as it highlights the importance of mosquito bite prevention strategies, especially in areas where dengue is endemic.
The Dengue Vaccine
Is There a Vaccine for Dengue?
Yes, there is a vaccine for dengue fever known as Dengvaxia. It is the first vaccine approved for the prevention of dengue and is recommended for individuals aged 9 to 45 years who have had at least one previous dengue infection. The vaccine is administered in three doses over a 12-month period and has been shown to reduce the risk of severe dengue and hospitalisation in those who have previously been infected with the virus. However, it is not recommended for individuals who have never been infected with dengue, as it may increase the risk of severe dengue upon subsequent infection.
Who Should Get Vaccinated?
The dengue vaccine is particularly recommended for travellers who are planning to visit areas where dengue is endemic, especially if they have a history of previous dengue infections. At Edinburgh Travel Clinic, we assess your travel history and health status to determine if the dengue vaccine is suitable for you. If you are travelling to regions with a high incidence of dengue, it is advisable to consider vaccination as part of your travel health preparations.
Importance of Vaccination
Benefits of the Dengue Vaccine
Vaccination against dengue fever provides several benefits, including:
Reduced Risk of Infection: The vaccine significantly lowers the risk of contracting dengue fever, especially in individuals who have had previous infections.
Prevention of Severe Cases: Vaccination helps prevent severe dengue, which can lead to hospitalisation and complications.
Peace of Mind: Knowing you are vaccinated can provide peace of mind while travelling in endemic areas, allowing you to enjoy your trip without the constant worry of mosquito-borne diseases.
Limitations of the Vaccine
While the dengue vaccine offers significant benefits, it is essential to understand its limitations:
Not for Everyone: The vaccine is not recommended for individuals who have never been infected with dengue, as it may increase the risk of severe dengue upon subsequent infections.
Not a Substitute for Other Preventive Measures: Vaccination should be part of a comprehensive strategy that includes mosquito bite prevention, such as using insect repellent, wearing protective clothing, and staying in well-screened or air-conditioned accommodations.
Preventive Measures Against Dengue
Mosquito Bite Prevention
In addition to vaccination, it is crucial to take preventive measures against mosquito bites, especially when travelling to dengue-endemic areas. Here are some effective strategies:
Use Insect Repellent: Apply a repellent containing DEET, picaridin, or oil of lemon eucalyptus to exposed skin.
Wear Protective Clothing: Opt for long-sleeved shirts and long trousers, preferably treated with permethrin, to reduce skin exposure.
Stay in Screened Accommodations: Choose hotels or lodgings that have proper screens on windows and doors to keep mosquitoes out.
Avoid Peak Mosquito Activity: Aedes mosquitoes are most active during the day, particularly early in the morning and late afternoon. Plan outdoor activities accordingly.

When travelling to areas where dengue is prevalent, it is also essential to consider other health risks. Ensure that you are up to date with routine vaccinations and consider additional vaccines based on your travel itinerary.
