目的评价如东县土源性线虫病综合防治效果,为制定防治策略提供依据。方法 1995年起,采取药物驱虫、健康教育、改水改厕等措施,对土源性线虫病进行综合干预。通过居民土源性线虫感染率、卫生知识知晓率和卫生行为合格率等指标评价综合防治效果。结果 1995-2013年全县共开展驱虫服药272.45万人次,自来水普及率99.16%,农村卫生厕所普及率95.50%,居民卫生知识知晓率由1996年基线调查时的45.07%上升至2013年的96.51%,差异有统计学意义(χ2=348.79,P<0.01)。卫生行为合格率由1996年的55.38%上升至2013年的96.32%,差异有统计学意义(χ2=247.44,P<0.01)。2013年土源性线虫感染率为0.15%,较1989年的73.27%下降了99.79%,差异有统计学意义(χ2=2786.30,P<0.01)。结论如东县通过实施综合防治策略和相关措施,有效控制了土源性线虫病的流行。
Objective To evaluate the comprehensive control effect of soil-borne nematodes in Rudong County and provide the basis for the development of control strategies. Methods Since 1995, we have taken measures such as drug deworming, health education, water improvement and toileting, and integrated intervention on soil-borne nematodes. The comprehensive prevention and control effects were evaluated by the indexes of soil infection rate of indigenous nematodes, the awareness rate of health knowledge and the passing rate of health behavior. Results From 1995 to 2013, the county carried out a total of 2,724,500 person-times of de-worming medication with a penetration rate of 99.16% for running water and 95.50% for rural restroom. The awareness rate of residents’ health knowledge rose from 45.07% at the baseline survey in 1996 to 96.51 in 2013 %, The difference was statistically significant (χ2 = 348.79, P <0.01). The passing rate of health behaviors increased from 55.38% in 1996 to 96.32% in 2013, with a significant difference (χ2 = 247.44, P <0.01). In 2013, the infection rate of soil-borne nematodes was 0.15%, which was 99.79% lower than that of 73.27% in 1989 (χ2 = 2786.30, P <0.01). Conclusion Rudong County effectively controlled the epidemic of soil-borne nematodes through the implementation of integrated prevention and control strategies and related measures.
