We previously reported a new community-based mosquito control strategy that resulted in elimination of Aedes aegypti (Linn.) in 40 of 46 communes in northern and central Vietnam, and with annual recurrent total costs (direct and indirect) of only $0.28-$0.89 international dollars per person. This control strategy was extended to four provinces in southern Vietnam in Long An and Hau Giang (2004-2007) and to Long An, Ben Tre, and Vinh Long (2005-2010). In a total of 14 communes with 124,743 residents, the mean ± SD of adult female Ae. aegypti was reduced from 0.93 ± 0.62 to 0.06 ± 0.09, and the reduction of immature Ae. aegypti averaged 98.8%. By the final survey, no adults could be collected in 6 of 14 communes, and one commune, Binh Thanh, also had no immature forms. Although the community-based programs also involved community education and clean-up campaigns, the prevalence of Mesocyclops in large water storage containers > 50 liters increased from 12.77 ± 8.39 to 75.69 ± 9.17% over periods of 15-45 months. At the conclusion of the study, no confirmed dengue cases were detected in four of the five communes for which diagnostic serologic analysis was performed. The rate of progress was faster in communes that were added in stages to the program but the reason for this finding was unclear. At the completion of the formal project, sustainability funds were set up to provide each commune with the financial means to ensure that community-based dengue control activities continued.
我们之前曾报道过一种新的基于社区的蚊虫控制策略，该策略在越南北部和中部的 46 个公社中消灭了埃及伊蚊（Linnaeus），并且每年的经常性总费用（直接和间接）仅为每人 0.28-0.89 国际美元。该控制策略已扩展到越南南部的隆安和后江省（2004-2007 年）以及隆安、槟椥和永隆省（2005-2010 年）。在总共 14 个有 124743 名居民的公社中，成蚊埃及伊蚊的平均 ± SD 从 0.93 ± 0.62 减少到 0.06 ± 0.09，未成熟埃及伊蚊的减少平均为 98.8%。在最后一次调查中，有 6 个公社的成虫无法采集到，一个名为 Binh Thanh 的公社也没有未成熟的幼虫。尽管基于社区的项目还包括社区教育和清理运动，但大型储水容器（>50 升）中中剑水蚤的流行率在 15-45 个月期间从 12.77 ± 8.39%增加到 75.69 ± 9.17%。在研究结束时，在进行诊断血清学分析的五个公社中，有四个公社未发现确诊的登革热病例。分阶段加入该计划的公社的进展速度更快，但原因尚不清楚。在正式项目完成时，设立了可持续性资金，为每个公社提供了财务手段，以确保基于社区的登革热控制活动继续进行。
