Advice for travellers
Dengue is spread by two types of Aedes mosquitoes. Both breed close to dwellings, are found in shady areas and bite mainly during the daylight hours, 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 PMD when outdoors to all exposed skin. Read more about dengue fever.
