我们根据《湖南省湖沼地区血吸虫病易感地带分级与分型的探讨》一文中,某地段危险指数(D·I)*的公式(参考湖南医学1988年第2期),对钱粮湖农场七分场血吸虫病化疗纵向观察点实施防治措施后,试以垸外易感地带危险指数的变化考核了其防制对策的效果。 According to the article “Discussion on classification and classification of susceptible zones of schistosomiasis in the lakes and marshes of Hunan Province”, a formula for the hazard index (D · I) of a lot (refer to Hunan Medical Science, No. 2, 1988) Longitudinal observation points of schistosomiasis chemotherapy points after the implementation of control measures, try to embankment susceptibility zone hazard index changes in the assessment of the effect of prevention and control measures.
