UK health experts are warning travellers to take extra precautions after The BMJ reported that chikungunya cases in the country have reached a 10-year high. The alert comes as clinicians and public health teams continue to monitor imported infections linked to travel, with the mosquito-borne virus gaining renewed attention across UK medical news coverage.

Why the latest warning matters for UK travellers
Chikungunya is a viral infection spread by infected Aedes mosquitoes and is known for causing fever and joint pain. The BMJ’s earlier reporting noted that UK cases in the first half of 2025 were all linked to travel and were mainly reported in England, especially London. That pattern has made travel advice and post-travel vigilance a priority for clinicians. ([bmj.com](https://www.bmj.com/content/390/bmj.r1746?utm_source=openai))
Public health concern has also been shaped by wider developments in mosquito-borne disease preparedness. In June 2025, the UK’s Commission on Human Medicines temporarily restricted use of the chikungunya vaccine IXCHIQ in people aged over 65 while officials reviewed safety reports. The decision underlined the attention being paid to both prevention and vaccine safety in the UK response. ([bmj.com](https://www.bmj.com/content/389/bmj.r1277?utm_source=openai))
Clinical vigilance remains important after travel
The BMJ’s medical news coverage has previously highlighted that chikungunya can be a potentially life-threatening infection and that imported cases remain a recurring issue for the UK. For doctors and patients alike, that means symptoms after travel should not be dismissed, particularly when fever is accompanied by joint pain.

Although the current UK risk is still tied to travel rather than local transmission, the increase in cases fits a broader pattern of tropical and vector-borne infections drawing more scrutiny from UK specialists. The BMJ has also previously reported on tickborne disease risks rising in the UK thanks to climate change, showing how environmental factors are increasingly relevant to infectious disease planning.

What patients and clinicians are being told
Travel health advice remains the main line of defence, with travellers urged to protect themselves from mosquito bites and seek medical attention if they become unwell after returning. The latest alert reinforces the need for awareness among both patients and healthcare professionals, especially in primary care and urgent care settings where imported infections may first appear.

For the UK, the significance of the story is not only the rise in numbers, but the reminder that vector-borne diseases once considered distant can quickly become part of routine clinical vigilance. As travel patterns expand and public health guidance evolves, chikungunya is now firmly on the radar of clinicians watching for imported infectious threats.
