Jetting off in search of some winter sun this January? Travelling to tropical and subtropical destinations is a must on many people’s bucket lists. Whether you’ve bagged a last-minute deal in the January sales or you’re prepping for a big trip later this year, make sure you understand the risks of certain climates before packing your bags.
Dengue fever is a virus transmitted through the bite of infected Aedes mosquitoes. These mosquitoes are commonly found in tropical and subtropical regions such as: Southeast Asia, the Indian subcontinent, the Pacific Islands, Central and South America, the Caribbean, Africa, and parts of the Middle East. Popular travel destinations like Thailand, Brazil, Mexico, and Sri Lanka often report high numbers of cases, particularly during the rainy season when mosquito populations thrive.
The good news? With a little preparation and vigilance, you can significantly reduce your risk of contracting dengue fever while enjoying your travels. Here’s everything you need to know to stay safe.
What is Dengue Fever?
Dengue fever is caused by the dengue virus, which is transmitted through the bite of infected Aedes mosquitoes, primarily the Aedes aegypti and Aedes albopictus species. These mosquitoes are most active during the day, especially around dawn and dusk.
While many people infected with the virus are asymptomatic, dengue fever can cause some serious symptoms, including fever, severe headaches, muscle and joint pain, or skin rash.
With no specific antiviral treatment available, prevention is your best defence.
Top Tips to Protect Yourself from Dengue Fever
1. Get Vaccinated Before You Travel
Speak to one of our travel health specialists for advice on getting vaccinated against Dengue Fever, or for other prevention advice depending on the destination you’re travelling to. While it’s not suitable for everyone, it can be a valuable tool in reducing your risk if you’re travelling to high-risk areas.
2. Pack the Right Gear
Mosquito Repellent: Use a repellent containing DEET, picaridin, or IR3535, and reapply it regularly, especially if you’re sweating or swimming.
Protective Clothing: Wear long-sleeved shirts, trousers, and socks. Light-coloured clothing is less attractive to mosquitoes.
Mosquito Nets: If you’re staying in rural areas or accommodation without air conditioning, sleep under a treated mosquito net for added protection.
3. Be Smart About Your Accommodation
Choose hotels or guesthouses with air conditioning or screened windows and doors.
Avoid staying near areas with stagnant water, such as ponds, open drains, or water tanks, where mosquitoes are likely to breed.
4. Stay Vigilant During Peak Mosquito Hours
Aedes mosquitoes are most active during the day, particularly in the early morning, late afternoon and dusk. Minimise outdoor activities during these times, or take extra precautions if you’re out and about.
5. Eliminate Mosquito Breeding Sites
If you’re staying in a long-term rental or with friends and family, help reduce mosquito populations by:
Emptying containers that collect water, like buckets or flower pots.
Covering water storage tanks.
Ensuring that drains and gutters are clean and free of standing water.
6. Stay Informed About Local Outbreaks
Keep an eye on local news and health updates during your trip. If there’s an outbreak in your area, take extra precautions and avoid mosquito-prone environments.
What to Do If You Suspect Dengue Fever
If you develop symptoms such as high fever, severe headache, muscle and joint pain, or skin rash while travelling or after returning home, seek medical attention immediately. Early diagnosis is essential to manage symptoms and prevent complications.
Let your doctor know about your travel history so they can consider dengue fever as a possible cause.
Dengue fever doesn’t have to ruin your travel plans. By taking proactive steps to protect yourself and staying informed, you can minimise your risk and focus on enjoying your trip.
