Advice

The risk of exposure to dengue will vary from place to place and from low to high. The absence of reports from other states does not mean that there is no dengue fever transmission there.

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.
