Abstract:

Objective To analyze the main endemic indicators and their changing trend of schistosomiasis since the founding of new China for 60 years in Dongting Lake regions. Methods A variety of archival data on schistosomiasis epidemiology and control were collected，and several mathematical models were applied to estimate the main endemic indicators of schistosomiasis. Results Compared to those in 1950s，the infection rates of schistosomiasis among human and cattle in 2010 were declined by 89.3% and 94.7%，respectively；the number of schistosomiasis patients was reduced from 600 thousand to 88 thousand；the number of acute schistosomiasis patients dropped from 2 732 to 18；and that of advanced schistosomiasis patients decreased from 55 thousand to 5 632. Conclusions The high priority by government authority，suitable control models according to local conditions and huge resources are the cornerstone of success on schistosomiasis control in Dongting Lake regions.

摘要：

目的 分析新中国成立60年来洞庭湖区血吸虫病主要疫情指标及其变化趋势。方法 收集洞庭湖区血吸虫病流行及防治档案资料， 采用有关数学模型推算不同时期洞庭湖区血吸虫病主要疫情指标。 结果 与20世纪50年代相比， 2010年洞庭湖区居民和耕牛血吸虫感染率分别下降了89.3%和94.7%； 病人数从60万人下降至8.8万人； 急性血吸虫病人年发病数从2 732例下降至18例； 晚期血吸虫病人数从5.5万例下降至5 632例。结论 政府高度重视、 因地制宜调整防治模式， 大规模资源投入是洞庭湖区取得血吸虫病防治良好效果的主要原因。
