Objective To analyze the trend of schistosomiasis prevalence in Anhui Province from 2008 through 2014 for scientific evidences to plan commensurable prevention strategies in the coming mission. Meth?ods Informative data on schistosomiasis prevention were collected from annual reports, monitoring sites and management documentation in 51 counties/cities/districts in Anhui Province from 2008 to 2014, and reviewed in longitudinal cohort manner. Results The average infection rate of schistosomiasis and the number of patients tended to decline in general. The infection rate was reduced to 0.24%in 2014 from 48.2%in 2008. Current in?fected population and advanced schistosomasis cases were 16 510 and 5 804, with a decrease of 55.2% and 7.52%, respectively, as compared to 2008. No local infection with acute schistosomiasis was reported since 2013. The average infection rate of farmer cattle was fallen to 0.18% in 2014 from 88.8% in 2008, which showed a declining trend year by year. The proportion of snail presence was 27 280 hm2 in 2014, and dropped by 4.4%compared to that in 2008. The positive snail proportion further showed a yearly descending trend, and no areas where positive snails were found since 2013. Although recurrence or newly discovered areas with snail infection once rose up, yet this situation tended to be reverse since 2011. The density of snails and positive snails were reduced slowly since 2009, and the density of living snails was 0.4896 pcs/0.11 m2 in 2014 and re?duced to 29.6%compared with that in 2008. The quantity of villages and environment where snails or positive snails were still found were declined year by year, especially the environments with presence of positive snails were fallen sharply. More villages and towns realized the schistosomiasis transmission control target. Conclu?sion The prevalence of schistosomiasis was effectively contained in Anhui Province, and the endemicity was dropped to the lowest level in history.
