In recent years the region of the Americas has experienced increasing dengue activity with circulation of multiple virus serotypes. Associated with this trend has been the occurrence of sporadic dengue hemorrhagic fever (DHF) cases and of DHF epidemics in both the Caribbean and Latin America. High vector infestation levels persist even though most countries in the Caribbean conduct national Aedes aegypti control programs and despite the fact that in some instances, expenditures exceed US$5 per capita per annum. This paper critically reviews the resources and vector control strategies employed in the region and in selected neighboring countries. Reasons for the lack of progress include continued overreliance on eradication-style larviciding routines and the passive role of communities in addressing the problem. A policy of health promotion aimed at improving environmental health practices at the household and community levels has been endorsed by the governments of the region but as yet has not been widely adopted.
近年来，美洲地区登革热疫情不断加剧，多种病毒血清型在该地区传播。伴随着这一趋势，加勒比地区和拉丁美洲均出现了散发性登革出血热（DHF）病例以及DHF疫情。尽管加勒比地区大多数国家都开展了全国性的埃及伊蚊控制项目，且在某些情况下，人均年支出超过5美元，但病媒滋生水平仍然居高不下。本文对该地区及部分邻国所采用的资源和病媒控制策略进行了批判性审视。缺乏进展的原因包括持续过度依赖根除式的杀幼虫程序以及社区在解决该问题方面的被动作用。该地区各国政府已认可一项旨在改善家庭和社区环境卫生做法的健康促进政策，但尚未得到广泛采用。
