The United Kingdom has seen a surge in chikungunya infections, with the UK Health Security Agency (UKHSA) reporting more than 70 cases in just the first half of 2025. This figure is nearly three times higher than the 27 cases recorded during the same period last year, raising concern among health authorities.
Chikungunya, a mosquito-borne viral illness, is known for causing sudden high fever and severe joint pain. While it is rarely fatal, the long-term effects can be debilitating, with some patients experiencing persistent joint discomfort for months or even years. Although most people recover within a fortnight, the UKHSA has highlighted the increasing risks faced by travellers visiting countries where the virus is prevalent.
According to official findings, all reported UK cases have been linked to overseas travel, particularly to Sri Lanka, Mauritius, and India, where recent outbreaks have been recorded. Importantly, the mosquitoes that transmit the virus are not present in the UK, so there is no risk of local transmission.
Authorities Stress Need for Traveller Awareness
Public health experts emphasise that travellers need to be vigilant when visiting regions where mosquito-borne illnesses are common. Dr Philip Veal, a consultant in public health with UKHSA, cautioned that even though the virus cannot spread within Britain, travellers risk bringing it home.
He urged the public to adopt basic protective measures such as applying insect repellent, wearing long-sleeved clothing, and using insecticide-treated nets when sleeping. He also encouraged people to consult official travel health websites before flying and consider vaccination if heading to high-risk destinations.
The recent rise in cases has prompted warnings that even short holidays could expose travellers to the virus. With mosquito populations thriving in warmer climates, particularly in South and Southeast Asia, the risks remain significant for holidaymakers.
Global Outbreaks and Singapore’s Relevance
Chikungunya is not new to Southeast Asia, with outbreaks previously recorded in countries like Malaysia, Thailand, and Indonesia. For Singapore travellers, the warning is timely, as many popular holiday spots in the region are affected. While Singapore has robust mosquito control programmes, overseas trips to endemic countries may expose locals to the virus.
With international travel steadily increasing, health officials are urging Singaporeans and other global travellers to take preventive steps seriously. Protecting against mosquito bites is not just about avoiding discomfort—it can prevent long-term health consequences and reduce the spread of imported cases.
This surge in UK cases serves as a reminder of the ongoing risks posed by mosquito-borne diseases, reinforcing the need for awareness and responsible travel precautions.
