目的探讨四川省血吸虫病传播控制地区疫情回升的影响因素,为遏制疫情回升的措施提供基础。方法选择2007-11/12对疫情回升的德阳市旌阳区和中江县28个自然村的常住人口进行粪检中的阳性者为病例,粪检阴性者为对照组,采用1∶2匹配的病例对照研究,按性别、年龄±2岁匹配,共收集161对病例和对照。采用Remark Of-fice OMR 6.0和Epidata 3.1建立数据库,Epi Info 2000对数据进行单因素和多因素条件Logistic回归分析。结果经过多因素条件Logistic检验,家养黄牛(OR=1.759,P=0.02)和接触疫水(OR=2.381,P=0.008)是四川省血吸虫病传播控制地区疫情回升的危险因素。结论黄牛和减少接触疫水是四川省血吸虫病传播控制地区疫情回升的干预重点。
Objective To explore the factors influencing the recovery from schistosomiasis control in Sichuan Province and provide the basis for the measures to curb the rise of the epidemic. Methods The positive population of the resident population in Jingyang District, Deyang City and the natural villages of 28 natural villages in Zhongjiang County, 2007-11 / 12 were selected as the positive cases and the fecal negative patients as the control group. The patients in the 1: 2 matched cases Control study, by sex, age ± 2 years matched, a total of 161 pairs of cases and controls were collected. A database was constructed using Remark Of-fice OMR 6.0 and Epidata 3.1, and Epi Info 2000 was subjected to one-way and multivariate logistic regression analysis. Results Logistic regression analysis showed that domestic cattle (OR = 1.759, P = 0.02) and contact water (OR = 2.381, P = 0.008) were the risk factors for the rise of schistosomiasis control in Sichuan. Conclusion The reduction of contact with cattle and the epidemic of sepsis in Sichuan Province is the focus of intervention in the area of transmission control of schistosomiasis.
