目的 了解芜湖市镜湖区辖区范围内托幼机构消毒状况,提高和加强托幼机构消毒质量,对托幼机构传染性疾病的发生进行有效控制。方法 2015-2019年分别监测15家(次)、36家(次)、19家(次)、20家(次)、16家(次)托幼机构,采用现场采样和微生物检测的方法对5年内共采集的636份样本进行检测分析,对托幼机构室内空气(静态)、物体表面、玩具、工作人员手、幼儿手、餐(饮)具进行消毒效果监测。结果 2015-2019年间芜湖市镜湖区共监测托幼机构106家(次),检测样本636份,合格样本463份,合格率为72.80%,5年间2017年合格率最低(55.26%),2018年合格率最高(83.33%),不同年份合格率差异具有统计学意义(χ²＝36.212,P＜0.001);不同样本合格率比较,发现室内空气的合格率最高(97.17%),最低的是幼儿手(46.23%),不同类型样本检测合格率差异具有统计学意义(χ²＝127.241,P＜0.001);幼儿手检测合格率在公办托幼机构显著高于民办托幼机构(χ²＝3.939,P＜0.05)。结论 芜湖市镜湖区5年托幼机构消毒质量不稳定,物体表面、工作人员手和幼儿手合格率均相对较低,需要进一步加强管理,提高辖区内托幼机构的消毒质量。

Objective To understand the disinfection status of nursery institutions within the jurisdiction of Jinghu District in Wuhu City,improve and strengthen the disinfection quality,and effectively control the occurrence of infectious diseases in nursery institutions. Methods From 2015 to 2019,15 kindergartens (Times),36 (Times),19 (Times),20 (Times) and 16 (Times) kindergartens were monitored respectively.The methods of field sampling and microbiological detection were used to detect and analyze 636 samples collected in 5 years.The disinfection effect of indoor air (static state),object surface,toys,staff hands,children's hands and tableware (drinking) in kindergartens was carried out monitoring. Results From 2015 to 2019,106 nursery institutions in Jinghu District of Wuhu City were monitored and 636 samples were tested,463 of which were qualified,and the qualified rate was 72.80%.The qualified rate had fluctuated in the past five years,and the qualified rate in 2017 was the lowest (55.26%).The difference was statistically significant in different years (χ²=36.212,P＜0.001).The qualified rate of different types of samples showed that the qualified rate of indoor air was the highest (97.17%),and the lowest was children's hand (46.23%),the difference in different types of samples was statistically significant (χ²=127.241,P＜0.001).The qualified rate of hands of children in public nursery institutions was significantly higher than that in private nursery institutions (χ²＝3.939,P＜0.05). Conclusion The disinfection quality of kindergartens in Jinghu District of Wuhu City in five years is unstable,and the qualified rate of object surface,staff hands and children's hands is relatively low.It is necessary to further strengthen the management and improve the disinfection quality of nurseries and kindergartens in the area.
