Advice For Travellers

While the almost 140,000 reported cases may seem like a lot, registered cases represent only a small fraction of the actual cases in the community. Because 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. The risk of exposure for the general traveller may be high in some areas. Chikungunya virus infections may have long lasting health consequences.

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.
