Advice for travellers
Dengue is spread by Aedes mosquitoes which breed in shady areas close to habitations and bite mainly during the daylight hours, making them difficult to avoid outdoors. Travellers should cover up with long-sleeved tops, long pants, and shoes and socks when mosquitoes are most active. Apply an effective 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.
