According to statistics of Centers for Disease Control, R.O.C.(Taiwan), there were 43,419 confirmed cases of dengue fever in 2015. The cases were mainly in Kaohsiung city (19,723cases) and Tainan city (22,760cases), and the death toll stood at 214 which was more than last year. Hence, the purpose of this project was to provide accurate guidance of dengue control through dengue vector surveillance, outdoor breeding sources cleanliness, environmental education, improving the public’s knowledge of prevention and control, attitude and behavior for the community. The implementation of outdoor weekly investigations on the density of dengue vector mosquitoes on a regular basis within 12 boroughs of high dengue fever risk areas among Kaohsiung and Pingtung was completed. Because of the bursting cases this year, the surveillance distance was increased within 2 boroughs. There were 5 ovitrap breeding traps every borough, hence, 70 traps were set within 14 boroughs. Besides, the results of ovitrap were uploaded on specific websites, and provided related suggestions on breeding sources cleanliness of dengue vector. The campaign of breeding sources cleanliness was held at least 115 times by local environmental protection agencies, this record was able to lower the risk of case occurring. 306 sites of outdoor breeding sources investigation and elimination were completed in Kaohsiung and Pingtung in order to prevent dengue vectors. The results showed that outdoor breeding sources containers were styrofoam-made products, plastic products and disposable tableware the most. In Kaohsiung and Pingtung, 9 environmental education campaigns of breeding sources cleanliness were held, which dengue fever occurred before to educate heads of boroughs and neighborhoods, community volunteers, students and the public, in sum, there were 1,209 participants in these campaigns based on the statistic. Promoting dengue vector self-checks in the communities and utilizing the society common view to eliminate dengue vectors were expected to influence 10 thousand people. There were various methods of evaluation of environmental education effectiveness. In order to enhance the impression, the prize-giveaway quiz method was given to the public and primary school students; in order to propagate the environmental education of dengue fever and improve execution via commitment, the countersignature was initiated among junior high school students; in order to evaluate the effectiveness, the questionnaires were distributed to university students before and after the environmental education of dengue fever. There were 102 completed questionnaires, and the result of the survey showed a definite improvement in the knowledge, attitude and behavior of dengue fever control was obvious based on the statistics after environmental education (p <0.05). In an effort to understand the public’s knowledge, attitude and behavior of dengue fever control, questionnaires were distributed to the public before the environmental education. The completed questionnaires were 613, and the result of the survey showed that the public could answer most of the questions correctly. This indicated that the public, who participated in the project this year, might have participated in many environmental educations in advance. Therefore, the continuous effort of promoting and conducting breeding sources cleanliness among the public would be essential to prevent dengue fever in the future.
