The UK Health Security Agency (UKHSA) reports a significant increase in travel-associated chikungunya cases, with 73 cases from January to June 2025 compared to 27 in the same period in 2024.
This rise, linked to travel to Sri Lanka, India, and Mauritius, highlights the need for heightened vigilance among UK travellers.
Understanding the Surge
The recent surge in chikungunya cases among UK travellers is a cause for concern. The disease is transmitted by Aedes mosquitoes and causes symptoms like fever and joint pain.
While these mosquitoes are not established in the UK, the increase underscores the importance of preventive measures for those traveling to affected regions.
Most of these cases have been linked to travel to countries experiencing outbreaks such as Sri Lanka, India, and Mauritius. This trend emphasizes the need for travellers to take precautions like using insect repellent and considering vaccination before visiting high-risk areas.
Vaccination Options
- IXCHIQ® vaccine available for ages 18-59
- Vimkunya® vaccine available for ages 12+
- Both vaccines approved for private use in the UK
The Oropouche Virus Emergence
The UK has also recorded its first three cases of Oropouche virus, associated with travel to Brazil. Unlike chikungunya, this virus is spread by midges rather than mosquitoes. The emergence of this new vector-borne disease highlights evolving risks associated with international travel.
Travel Precautions
- Avoid mosquito bites by using insect repellent and wearing protective clothing
- Consider vaccination if traveling to high-risk areas
- Stay informed about health advisories through resources like Travel Health Pro
Healthcare Implications
The rise in chikungunya cases has implications beyond individual health concerns. Healthcare providers may see increased demand for diagnosis and treatment services.
Additionally, businesses could face workforce challenges if employees experience prolonged symptoms affecting their productivity.
A Public Health Perspective
“Chikungunya can be a nasty disease and we’re seeing a worrying increase in cases among travellers returning to the UK,” said Dr Philip Veal, Consultant in Public Health at UKHSA.
“While this mosquito-borne infection is rarely fatal, it can cause severe joint pain that may last months or longer.”
