Advice For Travellers

The absence of reports from other countries does not mean that the virus is not present there.

Chikungunya virus has infected well over 1 to 2 million people in the Americas since it arrived in 2013. The virus is well established in the mosquito population of temperate and tropical countries. While the risk of exposure will vary from place to place and from time to time, all travellers to areas where chikungunya fever virus is active can reduce their risk of exposure to this virus by taking all necessary precautions to avoid mosquito bites. Many persons with chikungunya fever do not seek medical care and are not reported to health authorities. There may be many more cases in the community that are not reported. Chikungunya virus infections may have long lasting health consequences.
