How do I prevent getting dengue while travelling?

Question

Hi doctor,

I have been hearing a lot about dengue fever and how it is spreading through Asian tiger mosquitoes in many places. I am a bit worried because I have travel plans coming up and want to understand the risks better. It sounds pretty serious, and I am concerned about its increasing prevalence. Is it really becoming a problem in many countries? What precautions should I take to protect myself from mosquito bites, especially in areas where dengue is present? How can I stay safe during my travels and what signs should I look out for if I start feeling unwell?

Kindly assist.

Hello,

I am glad you chose icliniq for your medical-related queries.

I can understand your concern.

Dengue fever, a viral infection spread by the Asian tiger mosquito (Aedes albopictus), is indeed becoming more prevalent in parts of some countries due to increasing temperatures and global travel. The Asian tiger mosquito, which can carry the dengue virus, has been spreading in some countries. Warmer temperatures and higher humidity are creating favorable conditions for these mosquitoes to thrive.

Precautions to protect yourself from mosquito bites:

Apply repellents containing DEET (N, N-diethyl-meta-toluamide), picaridin, or oil of lemon eucalyptus on exposed skin.
Wear long-sleeved shirts, long pants, socks, and shoes to minimize exposed skin.
Sleep under mosquito nets, especially in areas with a high risk of dengue.
Stay in air-conditioned or well-screened rooms. Mosquitoes are less likely to enter such environments.
Avoid peak mosquito activity times like dawn and dusk.

Staying safe during travel:

Choose accommodations with proper mosquito control measures.
Avoid areas with standing water where mosquitoes breed.
Visit a travel clinic before your trip for advice on vaccinations and additional precautions.

Early symptoms of dengue fever may include high fever, severe headache, pain behind the eyes, joint and muscle pain, rash, and mild bleeding (such as nose or gum bleeding). Severe symptoms include persistent vomiting, severe abdominal pain, rapid breathing, bleeding gums, fatigue, and restlessness. If you develop symptoms of dengue fever, especially after visiting areas where the disease is present, consult a healthcare provider immediately.

Drink plenty of fluids to stay hydrated.
Get ample rest to help your body fight the infection.

By taking these precautions and being vigilant about symptoms, you can significantly reduce your risk of dengue fever and enjoy your travels safely.
