Dengue fever is a potentially deadly mosquito-borne illness that is common in tropical and subtropical regions around the world. However, in recent years, there have been reports of dengue fever cases in some parts of Europe. The question is, should you be worried about contracting dengue fever on your next European holiday? In this article, we will explore the risk of dengue fever in Europe and provide tips on how to stay safe while traveling.
Dengue fever, a disease commonly associated with tropical regions around the world, is on the rise in several parts of Europe due to climate change, warn researchers. Following an outbreak of over 30 cases in the south of France in 2022, a woman from the UK reported having been infected while vacationing there in September of that year. Although the woman experienced a fever, headache, muscle pain, and a rash, she did not require further medical attention. Dr. Owain Donnelly from the Hospital for Tropical Diseases in London said that this case “highlights the rapidly changing epidemiology of dengue” and that if climate change continues, especially with hotter temperatures and more rainfall, the risk of dengue fever outbreaks could spread further throughout Europe.
According to the NHS, Dengue fever is a virus found in many parts of the world and is associated with travelling. The virus is most common in tropical areas of Asia, Africa, Central and South America, the Caribbean, the Pacific islands, and southern parts of North America. However, it is possible to contract the virus in some parts of southern Europe during specific times of the year. Dengue fever is passed by infected mosquito bites, and the mosquitoes that carry it bite during the day. Therefore, wearing long clothes that cover arms and legs, using repellent sprays, and keeping doors and windows closed to prevent bugs from coming in are all recommended measures to avoid mosquito bites.
Symptoms of dengue fever typically include fever, headache, pain behind the eyes, nausea, and feeling achy. A visible red blotchy rash may also appear. It is important to note that while 75% of cases are asymptomatic, if symptoms are experienced, they will usually appear four to ten days after being bitten.
If you feel unwell after traveling to a country where dengue fever is found, the NHS recommends calling 111 or asking for an urgent GP appointment. Although most cases of dengue fever are mild and will pass on their own, severe dengue cases are also possible. Symptoms of severe dengue include abdominal pain and nausea, breathing difficulties, passing blood, exhaustion, or restlessness. Anyone experiencing these symptoms should seek medical help immediately.
While Dengue fever can be unpleasant, it typically resolves on its own within a few days without the need for medical treatment. Therefore, the risk of infection in Europe remains low despite reported cases. However, those who are medically vulnerable, such as people with weak immune systems, the elderly, the very young, and pregnant women, may be advised to avoid countries where dengue fever incidents have been recorded. In conclusion, paying attention to preventive measures and seeking medical help if necessary is essential when travelling.
In conclusion, while dengue fever has been known to occur in parts of Europe, the risk for travelers remains relatively low. It is always important to take precautions such as wearing protective clothing, using insect repellent, and seeking medical attention if any symptoms arise. With proper preparation and awareness, your European vacation can be worry-free and enjoyable. Happy travels!
