Advice for travellers

Dengue fever is common in most tropical or sub-tropical regions of the world. The virus is spread by daytime-feeding Aedes mosquitoes and to avoid it and other insect-borne diseases, travellers should apply an insect repellent containing an effective active ingredient, such as DEET, Picaridin or oil of lemon eucalyptus (PMD), to exposed skin when outdoors during the day. In addition, cover up with long-sleeved tops, long pants, and shoes and socks around dawn and dusk, as well as other times when the mosquitoes are active.
