在登革热传播高峰结束时，对泰国chachengsao省6所学校的小学生进行了血清学调查。对血清阳性病例进行GIS分析以确定传播焦点。通过社区参与与当地政府合作，在疫源地以及治疗地区疫源地周围100米范围内实施了病媒控制。病媒控制策略包括减少传染源，同时使用纱罩，结合苏云金芽孢杆菌亚种。和致死性诱卵器。在疫源地继续实施病媒控制战略，直至雨季结束。利用昆虫学、血清学和临床参数监测媒介控制效果。结果显示，与未经治疗的地区相比，治疗地区的登革热媒介显著减少，血清阳性儿童和临床病例也有所减少。
A serological survey of primary school children from six schools in Chachoengsao Province, Thailand, was performed at the end of the peak of dengue transmission. GIS analysis of sero-positive cases was carried out to determine transmission foci. Vector control implementation was conducted in the foci and also within 100 meters around the foci in the treated areas by community participation in collaboration with the local government. Vector control strategies included source reduction together with the use of screen covers, a combination of Bacillus thuringiensis subsp. israelensis and Mesocyclops thermocyclopoides, and lethal ovitraps. Implementation of vector control strategies in the foci was continued until the end of the rainy season. Vector control effectiveness was monitored using entomological, serological, and clinical parameters. Results showed a significant reduction of dengue vectors as well as a decrease in sero-positive children and clinical cases in treated areas when compared with untreated areas.
