Study of schistosomiasis transmission interruption based on intensive agri-culture / 中国血吸虫病防治杂志

ABSTRACT

Objective To study the effect of schistosomiasis transmission interruption model based on intensive agriculture in hilly endemic areas,so as to provide the reference for the similar endemic areas. Methods Based on the development of in-tensive agriculture in Guanghan City,a comprehensive demonstration area of schistosomiasis control with measures such as new rural construction,hardening ditches,the adjustment of industrial structure and water remediation measures was constructed. Ji-nhua,Shiguan and Hongyan villages were chosen as the evaluation sites to comparatively analyze the indexes of intensive agri-culture and schistosomiasis control effects. Results Compared with the demonstration area before construction,in 2014,the harden rates of ditches and village roads were increased by 49.57％and 39.33％respectively;and the proportion of agricultural machinery increased by 25％. The positive rate of serological tests of schistosomiasis was decreased by 81.74％. The Oncomela-nia hupensis snail area was decreased from 2.44 hm2(2007)to 0(2014). The awareness rate of schistosomiasis control knowl-edge and correct behavior rate of the residents were increased from 51.28％ and 90.85％ to 91.29％ and 97.69％ respectively. The experience of the demonstration area ensured the entire Guanghan District achieved the schistosomiasis transmission inter-ruption criterion at the end of 2014. Conclusions The schistosomiasis control model of intensive agriculture combined with oth-er comprehensive measures has a good effect on interrupting the endemic of schistosomiasis,and it can realize the sustainable development of the agricultural economy and schistosomiasis control.
