Chikungunya fever will continue to expand in 2015 since there is a ready supply of mosquitoes to sustain the transmission of the virus. 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.
