Objective To evaluate the intervention effect of Yi?Han bilingual health education of schistosomiasis control. Methods Baimiao Village in Daqing Town,Xichang City,where Yi Nationality inhabited,was chosen as a pilot to carry out Yi?Han bilingual health education of schistosomiasis control from 2012 to 2015. The villagers and students in the pilot area were in?vestigated by questionnaires before and after the intervention to understand their awareness and correct behavior status on schis?tosomiasis control. Results After the intervention of Yi?Han bilingual health education of schistosomiasis control for 3 years, the awareness rate and the correct rate of behavior on schistosomiasis control of the villagers in the pilot area improved from 45.79%and 51.12%in 2012 to 97.80%and 98.78%in 2015. As for the students,the two rates mentioned above improved from 64.16%and 60.83%in 2012 to 100%and 98.89%in 2015 respectively,and all the differences between the rates before and af?ter the intervention were statistically significant( all P<0.01). Conclusion The intervention of Yi?Han bilingual health educa?tion of schistosomiasis control can obviously improve the knowledge awareness rates and the correct rates of behavior of the resi?dents and students in the gathering area of Yi Nationality.

Schistosomiasis control progress and endemic situation in Sichuan Province / 中国血吸虫病防治杂志

Objective To understand the schistosomiasis control progress and endemic situation,so as to provide the evi?dence for formulating the strategy of schistosomiasis elimination in Sichuan Province. Methods The schistosomiasis history da?ta,working reports of schistosomiasis prevention and control,schistosomiasis surveillance data,and data of schistosomiasis pre?vention and control capacity were collected and analyzed for the schistosomiasis control progress and epidemic situation in Sich?uan Province from 2004 to 2015. Results There were 63 schistosomiasis endemic districts in 11 cities in Sichuan Province, and the standard of schistosomiasis transmission interruption was achieved in the whole province in 2015. Currently,the area with Oncomelania hupensis snails was 2 537.54 hm2,and there were 1 769 advanced schistosomiasis patients. From 2004 to 2015,the accumulated survey area with snails was 433 065.80 hm2,and the area of snail control by molluscicides was 251 259 hm2. There were 26.017 144 million person?times of schistosomiasis blood tests and 7.89 million person?times of chemotherapy. There were 1.276 117 million head?times of cattle that received the schistosomiasis examinations. The schistosomiasis patients and livestock and the area with snails were decreased year by year. Since 2010,there were no local schistosome?infected resi?dents and livestock and since 2004,there were no schistosome?infected snails. However,in some area,the professional person?nel were less,the technology and hardware lagged behind,and the schistosomiasis prevention and control capacity was weak. Conclusions Sichuan Province achieved the standard of schistosomiasis transmission interruption in 2015. In the future,the comprehensive schistosomiasis prevention and control strategy still should be strengthened,including the promotion of schistoso?miasis prevention and control capacity,establishment of sensitive early?warning surveillance system,and implementation of ac?curate schistosomiasis prevention and control,in order to consolidate the control achievements and realize the aim of schistoso?miasis elimination as soon as possible.
