目的全面了解广州市海珠区托幼机构消毒卫生现状和发展趋势,为控制和减少各类传染病发生和流行提供科学依据。方法对广州市海珠区2004—2009年托幼机构消毒监测结果进行统计分析。结果 6年来共监测托幼机构774家,采集样品14405份,总合格率90.82%。消毒液、玩具、空气、物体表面合格率较高,分别为99.42%、96.59%、96.59%、96.28%,紫外线灯合格率较低,为40.19%;各年度监测项目中,空气合格率年度间有下降趋势,差异有统计学意义(χ2=31.30,P<0.05);2008—2009年,3种不同规模人数的托幼机构监测合格率差异无统计学意义(χ2=1.74,0.69,P>0.05);细菌总数、金黄色葡萄球菌、溶血性链球菌、大肠菌群合格率较高,达94.21%以上,紫外线强度合格率较低。结论海珠区托幼机构消毒质量趋势良好,但仍存在薄弱环节,紫外线和老师手消毒卫生质量有待进一步提高。
Objective To comprehensively understand the current situation and development trend of disinfection and health in kindergartens and nurses in Haizhu District, Guangzhou, and provide scientific evidences for controlling and reducing the occurrence and prevalence of various infectious diseases. Methods The statistical analysis of disinfection monitoring results of nurseries in 2004-2009 in Haizhu District of Guangzhou City was conducted. Results A total of 774 nurseries and kindergartens were monitored over the past six years. A total of 14,405 samples were collected, with a total pass rate of 90.82%. The passing rate of disinfectant, toys, air and objects was higher, which were 99.42%, 96.59%, 96.59% and 96.28% respectively, and the pass rate of UV lamp was relatively low, which was 40.19%. In the annual monitoring items, (Χ2 = 31.30, P <0.05). From 2008 to 2009, there was no significant difference in the qualification rate of three nurseries with different scales (χ2 = 1.74,0.69, P> 0.05). The total number of bacteria, Staphylococcus aureus, hemolytic streptococcus, coliform bacteria higher pass rate of 94.21%, lower pass rate of UV intensity. Conclusion The disinfection quality of kindergarten-nurseries in Haizhu District is good, but there are still some weak points. The quality of hand hygiene by UV and teachers needs to be further improved.
