Advice For Travellers

Dengue fever virus is found in most regions of Brazil since the mosquito that transmits this infection is present throughout the country. Travellers to areas where the dengue fever virus is active can reduce their risk of exposure by taking all necessary precautions to avoid mosquito bites. Many persons with dengue fever do not seek medical care and are not reported to health authorities. There may be many more cases in the community than the reports indicate.
