British holidaymakers are being urged to take urgent precautions as health experts warn of a dramatic surge in dangerous dengue fever cases across popular European destinations.
The UK Health Security Agency (UKHSA) has issued a stark alert after reported cases of the potentially deadly mosquito-borne disease skyrocketed across southern Europe, including France, Italy, and Spain.
Exponential Rise in Infections
Health authorities have recorded an alarming increase in dengue fever incidents, with cases jumping from just 70 in 2022 to over 1,300 in the past year. This represents one of the most significant dengue outbreaks ever seen in European territories.
Professor Dame Jenny Harries, Chief Executive of UKHSA, emphasized the seriousness of the situation: "Climate change is creating increasingly favourable conditions for invasive mosquitoes across Europe, leading to growing dengue transmission rates in popular holiday destinations."
Understanding Dengue Fever
Dengue fever is a viral infection spread through the bite of infected Aedes mosquitoes, which typically bite during daylight hours. The disease can range from mild flu-like symptoms to severe, life-threatening complications.
Key symptoms to watch for include:
- High fever reaching 40°C
- Severe headache and eye pain
- Muscle and joint pain
- Nausea and vomiting
- Widespread skin rash
In severe cases, dengue can develop into haemorrhagic fever, which can prove fatal without proper medical treatment.
Protection Measures for Travellers
Health experts recommend that UK travellers visiting affected areas take comprehensive protective measures:
- Use EPA-registered insect repellents containing DEET, picaridin, or oil of lemon eucalyptus
- Wear long-sleeved shirts and long trousers in light colours
- Choose accommodation with air conditioning or screened windows
- Remove standing water sources where mosquitoes breed
- Consider permethrin-treated clothing for added protection
The UKHSA advises returning travellers who develop symptoms within two weeks of coming home to seek immediate medical attention and inform healthcare providers of their recent travel history.
Climate Change Fuelling the Spread
Experts attribute the expanding range of dengue-carrying mosquitoes to rising global temperatures and changing climate patterns. The invasive Aedes albopictus mosquito, capable of transmitting dengue, has now established populations in 13 European countries.
Professor Harries warned that this trend is likely to continue, with climate projections suggesting these mosquitoes could become established in England by the 2040s or 2050s due to warming temperatures.
This health alert serves as a crucial reminder for British travellers to prioritize protective measures and remain vigilant about potential health risks when visiting European destinations this holiday season.
