| Abstract: | 【Abstract】 Objective To analyze the trend of schistosomiasis endemic situation in Hexian County for planning upcoming strategies in this area. Methods The data of schistosomiasis control, including annual report, surveillance sites and routine management, in Hexian County were collected from 2008 to 2013, and vertically analyzed for the endemicity, distribution and characteristics of schistosomiasis in the past six years. Results Overall, the average infection rate of schistosomiasis in whole population of Hexian County tended to decline. The infection rate of population was decreased from 73.3% in 2008 to 0.27% in 2013, and the number of advanced schistosomiasis cases were 27, a 55% decrease compared to 2008. No local acute infection occurred since 2011. The infection rate for cattle was also significantly dropped to zero in 2013, with a 100% decrease compared to 2008. The areas with snail showed upward trend in general, and was 802.68 hm2 by the end of 2013, with 9.1% increase compared to 2008. However, the areas with infected snails were presented with yearly decrease, and no infected snails occurred after 2012. Although there was resurgence and new recurrence of snail, yet this situation was well managed. The density of live snails and infected snails was dropped by 56.8% in 2008 from 0.16 snails/0.11m2 . Apart from that, villages and environment with live snails and infected snails were declined in yearly fashion, particularly, the habitats with infected snails were grealy decreased. Conclusion The prevalence of schistosomiasis in Hexian County has been effectively contained, and the endemic situation remains lowest in history. |
