Abstract
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.
