Objective To provide the reference for schistosomiasis control through analyzing the changes of endemic status of schistosomiasis in China in recent years. Methods The annual data of schistosomiasis prevention and control from 2002 to 2012 were collected, and the descriptive analysis was conducted to describe the changes of schistosomiasis endemic status. Re?sults Sichuan, Yunan and Jiangxi provinces reached the criteria of transmission controlled from 2002 to 2010 while Hubei, Hu?nan, Jiangxi and Anhui provinces reached the criteria of infection controlled in 2008. The number of counties where the trans?mission of schistosomiasis was controlled decreased from 110 in 2002 to 80 in 2010. The numbers of estimated schistosomiasis cases and reported acute cases fell from 810.4 thousands and 913 in 2002 to 325.8 thousands and 43 in 2010, respectively, and they were reduced by 59.79%and 95.40%respectively. The number of infected bovine went down from 23 199 in 2002 to 7 173 in 2010, with a fall of 69.03%. However, the Oncomelania hupensis snails breeding areas kept in 3.7 to 3.8 billion m2 and among which, 125 million m2 areas were newly discovered in non?endemic areas during the nine years. In 2010, 90%of schistosomiasis cases, acute cases, infected bovine, and snail breeding areas were concentrated in 5 provinces, especially in the Dongting Lake and Poyang Lake areas and the regions along the Yangtze River. Conclusions The epidemic of schistosomiasis decreased sig?nificantly from 2002 to 2010. The lake regions are the key and tough areas for schistosomiasis prevention and control. To consoli?date the achievements, the surveillance and case management need to be strengthened as the extension of snail breeding areas and acute cases reported from other places becomes common.

Objective To assess the theoretical knowledge and practical skills of parasitic diseases among technicians from disease control and prevention institutions. Methods The Assessment on National Parasitic Disease Control and Prevention Techniques was organized in September,2015. Together,124 subjects from disease control and prevention institutions at prov-ince,prefecture or county levels in 31 provinces joined the assessment. A database was built consisting of subjects'basic infor-mation and assessment scores. Statistical analysis was used to analyze the scores by gender,age,professional title,institutions and places of participants. Results The average total score of all the subjects was 123.3,with a passing rate of 57.3%. The av-erage scores of male subjects(48 subjects)and female subjects(76 subjects)were 125.9 and 121.7 respectively;the average scores of the subjects aged under 30 years(57 subjects),between 30 and 40 years(61 subjects)and above 40 years(6 sub-jects)were 119.6,128.1 and 111.2 respectively;the average scores of persons with junior(94 subjects),intermediate(28 sub-jects)and senior(2 subjects)professional titles were 119.2,135.9 and 140.5 respectively. The average theoretical assessment score of all the subjects was 61.9,with a passing rate of 62.9%. The average practical skill assessment score of all the subjects was 61.4,with a passing rate of 58.1%. Conclusions The theoretical assessment results range widely. The theoretical knowl-edge results of technicians from disease control and prevention institutions are low in general. Therefore ,the specific training based on daily work needs to be enhanced.
