Easter Travel Alert: UKHSA Warns of Rising Mosquito-Borne Infections
The UK Health Security Agency (UKHSA) has issued an urgent warning to all travellers planning trips this Easter and throughout the spring season, amid a significant rise in mosquito-borne infections. Health officials are raising alarms as cases of chikungunya in England have reached their highest levels in over a decade, while malaria infections among returning travellers also remain persistently high.
Chikungunya Cases Surge to Decade High
According to the latest data, a total of 160 chikungunya infections were reported in England and Wales during 2025. All of these cases were directly linked to international travel, with the vast majority traced back to specific destinations in Asia and the Indian Ocean region. The primary sources included Sri Lanka, which accounted for 75 cases, India with 17 cases, and Bangladesh reporting 16 cases.
Symptoms and Health Risks Explained
Chikungunya infection typically manifests with a sudden onset of fever, often accompanied by severe joint pain. Other common symptoms include intense muscle aches, persistent headaches, heightened sensitivity to light, and noticeable skin rashes. While the infection is rarely fatal, it can lead to a prolonged and debilitating illness for many patients.
Dr. Philip Veal, a consultant in public health at UKHSA, emphasized the seriousness of the situation: "For some people, chikungunya can be a prolonged and nasty disease, and we continue to see cases in travellers returning to the UK, particularly from parts of Asia and the Indian Ocean region. While this mosquito-borne infection is rarely fatal, it can cause severe joint and muscle pain, headaches, sensitivity to light, and skin rashes."
Long-Term Effects and Prevention Measures
Although symptoms generally improve within a few weeks for most patients, joint pain can persist for months or even longer in some cases, significantly impacting quality of life. Dr. Veal stressed the importance of preventive measures: "Thankfully, symptoms usually improve within a few weeks, but joint pain may last for months or longer. So, it is essential to take precautions against mosquito bites when travelling."
The warning comes as malaria cases among returning travellers also remain at elevated levels, adding to public health concerns. Both infections share similar transmission vectors through mosquito bites, making preventive strategies crucial for anyone visiting affected regions.
Travel Advisory and Protective Steps
Travellers are advised to take comprehensive precautions when visiting areas known for mosquito-borne diseases. Recommended measures include using insect repellent containing DEET, wearing long-sleeved clothing, sleeping under mosquito nets, and staying in accommodations with proper screening. Health authorities also suggest consulting travel health clinics before departure for personalized advice and potential vaccinations.
The UKHSA continues to monitor the situation closely and urges all travellers to remain vigilant about their health during and after their journeys. Early medical attention is recommended for anyone experiencing symptoms upon return from affected regions.
