Results Since 2001, 286 127 people have been treated with medicine to repellent and a large range of drugs can effectively control the source of infection. At the end of 2016, the popularity rate of tap water was 100%, and the coverage rate of harmless toilets was 96.32%, which effectively cut off the way of transmission. The awareness rate of health knowledge of the students and residents increased form 35.96% and 35.84% in 1990 to 92.54% and 92.49% in 2015 respectively, the differences were statistically significant（χ^2students =177.27, χ^2residents=179.19, all P 〈0.01）. Intestinal nematode infection rate was 9.52% in 2000, and reducing to 0.13% in 2014, there was statistical significance between the two years（χ^2=255.23, P 〈0.01）. After 2010, the rate of population infection was controlled below 1%, which proved that the measures reduced the rate of infection in the population.
