Advice

There is a risk of exposure to dengue fever throughout most of Brazil, but the risk will vary from place to place depending on the extent of mosquito control.

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

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.
