On the military training facility of Tekong Island, Singapore, a comprehensive vector-borne disease control program was started in end-2006 to reduce mosquito populations and negate the need for anti-malaria chemoprophylaxis. The program was based on 1) preventing importation of malaria through screening of visitors, 2) preventing human-to-mosquito transmission through early case detection and mosquito control, 3) preventing mosquito-to-human transmission through personal protection, and 4) contingency plans. Systematic environmental works were performed to reduce breeding sites, and insecticide use targeted both adult mosquitoes and larvae. Mosquito populations declined from 103 mosquitoes per sampling site in January 2007 to 6 per site by March 2007 (P < 0.001). The proportion of positive ovitraps declined from 93% in January 2007-2% in March 2007 (P < 0.001). There were no malaria cases on the island despite chemoprophylaxis termination, showing that comprehensive combination vector-control strategies were effective in reducing the risk of malaria.
在新加坡的特刚岛军事训练设施上，2006 年底启动了一项综合性的病媒控制计划，以降低蚊虫数量，并消除对疟疾化学预防的需求。该计划基于以下 4 点：1）通过对访客进行筛查来防止疟疾的输入；2）通过早期病例检测和蚊虫控制来防止人传蚊；3）通过个人防护来防止蚊传人；4）制定应急计划。系统的环境工作减少了蚊虫滋生地，杀虫剂的使用针对成蚊和幼虫。蚊虫数量从 2007 年 1 月每个采样点 103 只下降到 2007 年 3 月的 6 只（P < 0.001）。阳性诱卵器的比例从 2007 年 1 月的 93%下降到 2007 年 3 月的 2%（P < 0.001）。尽管停止了化学预防，但岛上没有疟疾病例，表明综合的病媒控制策略在降低疟疾风险方面是有效的。
