Chikungunya fever increasing rapidly in Brazil

Chikungunya fever virus was first detected in Brazil in September. By mid-November, there were more than 1,300 reported cases in several states. The risk for the general traveller in major metropolitan centres is still low. However, where the virus is active, the risk can be high, and it is likely that there will be major outbreaks of this virus in many locations, similar to what has happened in countries in the Caribbean, Dominican Republic and El Salvador.

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.
