Health experts are sounding the alarm as cases of the dangerous Chikungunya virus among British travellers have more than tripled in recent years. This mosquito-borne disease, once confined to tropical regions, is now causing growing concern for UK holidaymakers.
What is the Chikungunya Virus?
The Chikungunya virus, transmitted through mosquito bites, causes debilitating symptoms including:
- Severe joint pain lasting months or years
- High fever reaching 40°C (104°F)
- Muscle pain and headaches
- Rash and fatigue
Why Are Cases Rising?
Public Health England reports a 220% increase in cases since 2019, with:
- Climate change expanding mosquito habitats
- Increased travel to affected regions
- Growing mosquito resistance to insecticides
The Hidden Danger: Organ Damage
While initially known for joint pain, new research reveals the virus can attack multiple organs:
- Heart: May cause myocarditis in severe cases
- Liver: Can lead to hepatitis-like symptoms
- Brain: Potentially triggers encephalitis
Protection and Prevention
Experts recommend these precautions for travellers:
- Use EPA-registered insect repellents
- Wear long sleeves and trousers in risk areas
- Sleep under mosquito nets
- Check travel advisories before trips
The NHS advises seeking immediate medical attention if symptoms appear within two weeks of returning from affected areas. While no specific treatment exists, early care can manage symptoms and prevent complications.
