Cases of dengue fever have been on the rise across Europe, with both locally-acquired and imported cases soaring last year due to hotter temperatures aiding the spread of disease-bearing mosquitoes. Climate change is contributing to the unpredictability of summer holiday planning, with flooded airports and heatwaves presenting challenges for tourists. Dengue-carrying tiger mosquitoes are now established in 13 European countries, including popular holiday destinations. Symptoms of dengue fever include flu-like symptoms such as high fever, severe headache, and muscle and joint pain, with severe cases potentially leading to fatal outcomes.
To protect yourself from mosquitoes while abroad, there are various personal protective measures you can take. This includes covering up in lighter-colored clothing, as mosquitoes are more attracted to dark materials. Wearing mosquito repellent containing DEET, IR3535, or Icaridin is essential, as mosquitoes carrying the dengue virus bite during the day. Precautions should also be taken at night, such as using mosquito bed nets or sleeping in an air-conditioned room. Eliminating stagnant water sources where mosquitoes breed, such as bottle caps of water, is crucial in reducing the risk of mosquito bites.
The symptoms of dengue fever typically appear between four and 10 days after infection and can last for two to seven days. In severe cases, dengue fever can progress to a potentially fatal illness, affecting up to five percent of people. The disease is more common in tropical areas of the world, such as parts of Africa, Asia, Central and South America, the Caribbean, the Pacific islands, and some southern areas of North America. It is important to be aware of the geographical hotspots for dengue fever and take appropriate precautions when traveling to these regions.
Mosquitoes are not just a nuisance but also a potential health hazard, especially in regions where diseases like dengue fever are prevalent. By taking simple measures to protect yourself from mosquito bites, such as using mosquito repellent, covering up, and eliminating stagnant water sources, you can reduce the risk of contracting dengue fever while traveling. Being aware of the symptoms of dengue fever and seeking medical attention if you suspect you have been infected is crucial in preventing the disease from progressing to a severe and potentially life-threatening condition.
With the spread of dengue-carrying mosquitoes in European countries, it is important for travelers to be informed about the risks of dengue fever and how to protect themselves while abroad. By following the recommendations of health authorities and taking proactive measures to prevent mosquito bites, tourists can enjoy a safe and healthy holiday experience. Climate change is creating challenges for travelers, but by staying informed and taking appropriate precautions, it is possible to reduce the risk of mosquito-borne illnesses such as dengue fever and ensure a pleasant and worry-free trip.
