摘要
目的 分析成都市中小学校厕所设计及其卫生情况与诺如病毒感染疫情规模的关系,为学校厕所设计和诺如病毒感染防控提供科学参考。方法 共纳入2019-2020年成都市78起诺如病毒感染疫情,分别发生在78所中小学校,发生原因为人传人,采用χ^(2)检验和Mann-Whitney U检验分析各变量与疫情规模的关系,采用二元非条件Logistic回归进行多因素分析。结果 78起疫情主要发生在2019年10-2020年3月(79.49%,62起)、小学(71.79%,56起)和主城区(52.56%,41起)。单起疫情涉及病例中位数为10例。在厕所冲水设计上,56所(71.79%)学校的厕所为独立冲水型,22所(28.21%)为统一冲水型。27所(34.62%)学校厕所水龙头数量设置不达标。多因素Logistic回归分析发现,相较于独立冲水的学校厕所,统一冲水的学校厕所其疫情规模更大(OR=5.53,95%CI=1.63~18.76,P<0.05)。结论 为更好地防控肠道传染病疫情,学校在改造或设计厕所时应尽量选择独立冲水式厕所,并配置充足的水龙头。
Objective To analyze the relationship between the toilet design and sanitary condition of primary and secondary schools in Chengdu and the epidemic situation of Norovirus infection,so as to provide scientific references for school toilet design and Norovirus prevention and control.Methods A total of 78 cases of norovirus epidemics from 2019 to 2020 were included in this study.These epidemics happened in 78 schools and the causes were indicated as human-to-human transmission.The Chi-square and Mann-Whitney U-test were used to compare categorical and continuous data respectively.Unconditional binary Logistic regression was used to examine the multivariate associations.Results Most epidemics happened from October in 2019 to March in 2020(79.49%,62 cases),in primary schools(71.79%,56 cases)and in the center area(52.56%,41 cases).The median of the case number in each epidemic was 10.Overall,56 schools(71.79%)were equipped with toilets which were flushed independently,and 22 schools(28.21%)were equipped with toilets which were flushed uniformly.There were 27 schools(34.62%)that did not have enough water taps.Logistic regression analysis found that those with toilets flushed uniformly had a stronger epidemic,compared to the schools with toilets flushed independently(OR=5.53,95%CI=1.63-18.76,P<0.05).Conclusion In order to prevent intestinal infectious diseases,it is suggested that schools should design or reconstruct independent flushing toilets with adequate faucets.
