In a further update of the dengue fever outbreak affecting the four territories, the ECDC reports an additional 1,700+ cases over the four weeks to May 31 – Martinique and Guadeloupe recorded 1,340 between them. The ECDC went on to note that ‘environmental conditions are favourable for continuous transmission. The concurrent circulation of several dengue serotypes may increase the risk of more severe clinical presentations.’ A May 21 CDC travel notice was issued for 14 countries in Central and South America, Mexico, and the Caribbean due to ‘higher-than-usual numbers of dengue cases’.
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.
