British travelers are being advised to be extra cautious while abroad following a significant increase in a dangerous mosquito-borne illness, as reported by the UK Health Security Agency (UKHSA).
Recent data indicates a surge in travel-related cases of chikungunya in England, with 73 cases recorded between January and June 2025. This number is nearly three times higher than the same period last year and marks a record high. Most affected individuals had recently visited countries like Sri Lanka, India, or Mauritius, where chikungunya outbreaks are prevalent.
Although the mosquitoes responsible for transmitting chikungunya are not native to the UK, health authorities are emphasizing the importance of vigilance for travelers. Chikungunya is a viral infection transmitted by specific mosquito species mainly found in tropical regions, typically causing sudden fever and severe joint pain, along with symptoms like headaches, muscle aches, skin rashes, and light sensitivity.
While the majority of individuals recover within weeks, joint pain can persist for an extended period, affecting up to 12% of patients for years. Although severe complications are uncommon, vulnerable groups such as young children, the elderly, and individuals with underlying health conditions face a higher risk of serious outcomes.
Dr. Philip Veal, a Public Health Consultant at UKHSA, highlighted the concerning rise in chikungunya cases among returning travelers, emphasizing the importance of preventive measures like using insect repellent, wearing protective clothing, and sleeping under treated bed nets. Travelers are advised to check the Travel Health Pro Website before trips for updated health guidance and consider chikungunya vaccination for high-risk regions.
Additionally, the UKHSA report disclosed three cases of Oropouche virus in the UK for the first time, all linked to travel in Brazil, where an outbreak is ongoing. Unlike chikungunya, Oropouche virus is primarily transmitted by midge bites and manifests as high fever, chills, headaches, joint pain, and muscle aches, posing heightened concerns for pregnant travelers.
Health experts stress the significance of early preparation for travel-related illnesses, recommending visits to the Travel Health Pro website well in advance of departure for comprehensive information on health risks, vaccinations, insect bite prevention, and food safety.
To safeguard against chikungunya specifically, protecting oneself from mosquito bites is crucial. Travelers are urged to take necessary precautions to minimize the risk of contracting mosquito-borne diseases while traveling.
