Advice For Travellers

The risk of exposure to dengue fever virus is widespread in Brazil, but the risk may vary form place to place and from low risk to high risk.

The absence of reports does not mean that there is no dengue fever transmission in other localities.

All 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.
