描述了一种新的登革热监测方法，并用于评估西印度群岛特立尼达岛圣帕特里克县的100例疑似登革热（DF）病例。在诊断后48小时内充分调查的30例确诊DF病例中，63%（19/30所房屋）的房屋被发现藏有埃及伊蚊未成熟阶段。只调查了索引病例的四个基点上的房屋，而不是整个社区。结果表明，Ae显著高于对照组（P < 0.001）。埃及伊蚊阳性房屋东（P < 0.04）、西（P < 0.01）多于北、南（P > 0.9）。此外，在检查的150间房屋中，共检查和处理了474个人工容器，其中20.8%（99个）感染了Ae。埃及未成熟阶段。超过49%的被检查的集装箱是小型杂项集装箱，但它们只产生了4.0%的Ae。未成年埃及人，其中只有0.4%是脓性的。水箱（41.7%）、桶（40.4%）和桶（24.2%）产生了98%以上的水。这项研究的结果意味着，在特立尼达的登革热病媒控制方案，可以提高他们的效率，在DF病例调查和集中在最具生产力的集装箱位于铸造和西部的索引情况下，他们的病媒控制措施的基点监测方法。(C)2007 Elsevier B.

A novel dengue surveillance method is described and used to evaluate 100 suspected dengue fever (DF) cases in county St. Patrick, Trinidad, West Indies. From the 30 confirmed DF cases fully investigated within 48 h of diagnosis, 63% (19/30 houses) of their homes were found harboring Aedes aegypti immature stages. Only houses at the four cardinal points of the index case rather than the entire neighborhood were investigated. The results showed significantly (P < 0.001) more Ae. aegypti positive houses were observed to the east (P < 0.04) and west (P < 0.01) than to the north and south (P > 0.9). In addition, from the 150 houses inspected a total of 474 artificial containers were inspected and treated, of which 20.8% (99) were infested with Ae. aegypti immature stages. More than 49% of the containers inspected were small miscellaneous containers, but they only produced 4.0% of the Ae. aegypti immatures, of which only 0.4% were pupae. Water tanks (41.7%), drums (40.4%) and buckets (24.2%) produced over 98% of the pupae. The results of this study imply that dengue vector control programs in Trinidad could increase their efficiency by applying the cardinal points surveillance approach during DF case investigations and concentrating their vector control measures on the most productive containers located at the cast and west of the index cases.
