Dengue hemorrhagic fever (DHF), a disease transmitted by Aedes mosquitos, remains a serious public health problem in Thailand. This paper describes the effect of health education efforts on a community-based DHF vector control program in the municipality of Mae Sot District, Tak Province, northern Thailand, from 1988 through 1990. In 1988, public health education on DHF and larval control through mass media, lectures and discussions reduced the Aedes Breteau index from 241 in March to 126 in June 1988. In 1989 and 1990, twice a year house-to-house visits by trained health workers were added to the health education campaigns. Aedes larval indices were decreased far more in the epidemic year of 1990 than in 1989. During this 3-year period, water-storage containers for drinking, washing, bathing and ant-traps were the primary sources of larval habitats, accounting for about 90% of the total breeding places. Reduction of Aedes larvae in these sources was due to various larval control measures. By August 1990 water containers for non-drinking purposes were the remaining important breeding places. The introduction of larvivorous fish may be an effective method of larval control for these containers. Most houses were supplied by public piped water system; however, a shortage of piped water for a period of time resulted in a significant increase in the number of water containers. An adequate water supply to the community should be provided continuously to prevent creation of new breeding places. Modifying behavioral practices to reduce domestic man-made water containers should be encouraged.
登革出血热（DHF）是一种由伊蚊传播的疾病，在泰国仍然是一个严重的公共卫生问题。本文描述了1988年至1990年期间，健康教育工作对泰国北部夜丰颂府夜丰颂区一个基于社区的登革热媒介控制项目的影响。1988年，通过大众媒体、讲座和讨论开展的登革出血热和幼虫控制方面的公共健康教育，使布雷图伊蚊指数从3月的241降至1988年6月的126。1989年和1990年，在健康教育活动中增加了由训练有素的卫生工作者每年两次的挨家挨户走访。1990年疫情年的伊蚊幼虫指数下降幅度远大于1989年。在这三年期间，用于饮用、洗涤、沐浴的储水容器和捕蚁器是幼虫栖息地的主要来源，约占总繁殖地的90%。这些来源中伊蚊幼虫数量的减少得益于各种幼虫控制措施。到1990年8月，非饮用水容器成为剩余的重要繁殖地。引入食蚊鱼可能是控制这些容器中幼虫的有效方法。大多数房屋由公共供水系统供水；然而，一段时间的供水短缺导致储水容器数量显著增加。应持续为社区提供充足的供水，以防止产生新的繁殖地。应鼓励改变行为习惯以减少家庭人造储水容器。
