Chikungunya is a disease spread to humans through the bite of an infected mosquito. It typically causes fever combined with arthritis-like pain in the joints. Travellers are at risk when visiting areas where chikungunya occurs and in areas being affected by a chikungunya outbreak. Chikungunya is found currently in Mexico and the Caribbean as well as Africa and Asia.
The risk is higher during the daytime, particularly around sunrise and sunset. Mosquitoes that
can transmit chikungunya bite even in shady areas, when it is overcast, or if you are indoors.
What are the symptoms?
Symptoms can take up to 12 days to appear, but usually begin within 3-7 days after being
bitten by an infected mosquito. They generally include fever and joint pain. Other symptoms can include fatigue, headache, nausea, vomiting, muscle pain, and rash.
Most people recover after a few days, though in some cases joint pain may persist for weeks or months. Gastrointestinal, eye, neurological and heart complications have sometimes been
reported. Complications are rare but can be more common in infants, older travellers and people with chronic medical conditions (for example, diabetes, hypertension).
Protect yourself from mosquito bites, particularly around sunrise and sunset. Those that may
be at higher risk of complications include infants, older travellers and people with chronic
Cover exposed skin by wearing long-sleeved shirts, long pants, and hats.
Use an appropriate (non aerosol) insect repellent as directed.
If you develop symptoms similar to chikungunya when you are travelling or after you return,
see a health care provider and tell them where you have been travelling or living.
