[Epidemic situation and control of soil-transmitted nematodiasis in Jiangsu Province].

Objective: To analyze the prevalence changes and the control measures of soil-transmitted nematodiases in Jiangsu Province in the recent 20 years and evaluate the control effect, so as to explore the control strategies and measures appropriate to current epidemic characteristics.

Methods: The data on surveillance, control measures and control effect of soil-transmitted nematodiases in Jiangsu Province from 1990 to 2009 were collected and analyzed.

Results: Different control programs were taken in different control stages in Jiangsu Province. A total of 106 916.6 thousand person-times accepted chemotherapy and 2 042.9 thousand person-times were surveyed in the last 20 years. The infection rate of soil-transmitted nematodiases was 1.31% in 2009, which decreased by 97.79% comparing with 59.32% in 1990. The results showed that the control effectiveness was significant.

Conclusions: The epidemic situation of soil-transmitted nematodiases has been controlled effectively in Jiangsu province. In order to consolidate the control achievements, the control strategies should put emphasis on health education, water supply and sanitation and environment sanitation improvement, meanwhile, the surveillance and medication in key population should continue to be strengthened, as well as soil-transmitted control among migrant population.
