Advice For Travellers

The risk of exposure to dengue fever is widespread in many countries, but it will vary from low to high from place to place within a country.

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

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.
