Dengue is a viral disease usually transmitted by Aedes aegypti mosquitoes. Dengue outbreaks in the Americas reported in medical literature and to the Pan American Health Organization are described. The outbreak history from 1600 to 2010 was categorized into four phases: Introduction of dengue in the Americas (1600-1946); Continental plan for the eradication of the Ae. aegypti (1947-1970) marked by a successful eradication of the mosquito in 18 continental countries by 1962; Ae. aegypti reinfestation (1971-1999) caused by the failure of the mosquito eradication program; Increased dispersion of Ae. aegypti and dengue virus circulation (2000-2010) characterized by a marked increase in the number of outbreaks. During 2010 > 1.7 million dengue cases were reported, with 50,235 severe cases and 1,185 deaths. A dramatic increase in the number of outbreaks has been reported in recent years. Urgent global action is needed to avoid further disease spread.
登革热是一种由埃及伊蚊传播的病毒性疾病。本文描述了医学文献和泛美卫生组织报告的美洲登革热疫情。从 1600 年到 2010 年的疫情历史分为四个阶段：登革热在美洲的传入（1600-1946 年）；消灭埃及伊蚊的大陆计划（1947-1970 年），该计划于 1962 年成功消灭了 18 个大陆国家的蚊子；埃及伊蚊再次滋生（1971-1999 年），原因是蚊子消灭计划失败；埃及伊蚊和登革热病毒传播的扩散加剧（2000-2010 年），其特点是疫情爆发数量显著增加。2010 年报告了超过 170 万例登革热病例，其中 50235 例为重症病例，1185 人死亡。近年来，疫情爆发的数量急剧增加。需要采取紧急的全球行动，以避免疾病进一步传播。
