The UK Health Security Agency (UKHSA) has reported a significant rise in travel-related cases of chikungunya virus, a mosquito-borne illness typically found in Africa and southern Asia. In the first half of 2025, 73 cases were confirmed in the UK—more than double the 27 cases reported during the same period in 2024.
Chikungunya is spread by Aedes aegypti and Aedes albopictus mosquitoes, neither of which are currently present in the UK. Symptoms include sudden fever, joint pain, and fatigue. While most people recover within weeks, some may experience persistent joint pain for months or even years. Fatal cases are rare.
Travel-Linked Outbreaks
Most UK cases were linked to travel in India, Sri Lanka, and Mauritius, where an outbreak is currently underway. UKHSA urges travellers to take precautions against mosquito bites, including:
- Using insect repellent
- Wearing protective clothing
- Sleeping under insecticide-treated bed nets
- Checking Travel Health Pro for destination-specific advice
A chikungunya vaccine may be considered for travellers heading to high-risk regions.
Emerging Threat: Oropouche Virus
UKHSA also confirmed the first UK cases of Oropouche virus, a disease normally found in Central and South America and the Caribbean. These cases were linked to travel in Brazil.
Unlike chikungunya, Oropouche virus is spread by midge bites. Symptoms include:
- High fever
- Chills
- Headache
- Joint and muscle pain
Pregnant travellers are advised to take extra precautions due to concerns about potential complications.

Travellers are encouraged to stay updated on mosquito- and midge-borne illnesses through official sources like UKHSA and Travel Health Pro.
