Health authorities in the UK and European Union are on high alert following reports of a growing chikungunya virus outbreak linked to travel from China. The mosquito-borne disease, which causes severe joint pain and fever, has prompted warnings for travellers and heightened surveillance.
What is the chikungunya virus?
Chikungunya is a viral infection transmitted by Aedes mosquitoes, the same insects that spread dengue and Zika viruses. Symptoms typically appear 3-7 days after being bitten and include:
- High fever
- Severe joint pain and swelling
- Muscle pain
- Headache
- Rash
While rarely fatal, the virus can cause debilitating pain that persists for months or even years in some cases.
Current outbreak situation
The current outbreak originated in China, with several confirmed cases now appearing in European countries. Health officials are particularly concerned about:
- The potential for local transmission if infected travellers are bitten by native mosquitoes
- The peak summer travel season increasing exposure risks
- Climate change expanding the habitat range of disease-carrying mosquitoes
Protection and prevention
Public health experts recommend:
- Using EPA-registered insect repellents
- Wearing long-sleeved clothing in affected areas
- Installing window screens or using air conditioning
- Eliminating standing water where mosquitoes breed
The UK Health Security Agency has advised travellers returning from affected areas to seek medical attention if they develop symptoms within two weeks of their trip.
