Advice for travellers
Dengue is spread by Aedes mosquitoes which breed in shady areas close homes and other accommodation. They bite mainly during the daylight hours and can be found indoors, making them difficult to avoid. Travellers should cover up with long-sleeved tops, long pants, and shoes and socks when mosquitoes are most active. Apply repellent containing an active ingredient, such as DEET, Picaridin, or oil of lemon eucalyptus (PMD) when outdoors to all exposed skin. Read more about dengue fever and preventing insect bites.
