The Chikungunya virus, a mosquito-borne illness, is causing concern among travellers visiting tropical and subtropical regions. This viral infection, primarily spread by Aedes aegypti and Aedes albopictus mosquitoes, has been reported in parts of Africa, Asia, and the Americas.
Symptoms of Chikungunya
Common symptoms include:
- High fever
- Severe joint pain
- Muscle aches
- Headache
- Rash
- Fatigue
While most patients recover fully, some may experience persistent joint pain for months or even years.
Who Is at Risk?
Travellers visiting affected areas are most vulnerable, particularly during peak mosquito activity hours (early morning and late afternoon). Those with weakened immune systems or chronic medical conditions may experience more severe symptoms.
Prevention Tips
To reduce infection risk:
- Use EPA-registered insect repellent
- Wear long-sleeved clothing
- Stay in air-conditioned or screened accommodations
- Remove standing water where mosquitoes breed
Treatment Options
Currently, there is no specific antiviral treatment for Chikungunya. Medical care focuses on relieving symptoms with rest, fluids, and pain relievers like acetaminophen.
If you develop symptoms after visiting an affected area, consult a healthcare provider immediately and mention your travel history.
