Objective To investigate factors associated with awareness of prevention and control of Norovirus outbreak among primary and middle school staffs in the Pearl River Delta region, to provide evidence for Norovirus outbreaks prevention and control.
Methods A total of 320 primary and middle school staffs from 48 schools in 3 cities in the pearl river delta region were selected by multistage quota random sampling method and were interviewed face to face with questionnaire about knowledge of Norovirus and prevention and control of Norovirus outbreaks.
Results The awareness rate of Norovirus knowledge and prevention and control of Norovirus outbreaks among primary middle school and the total school staffs in the pearl river delta region were 35.37%, 57.63% and 48.42%, respectively. The results of univariate analysis showed that the awareness rate of prevention and control of Norovirus outbreaks was significantly affected by duties, the total awareness rate among teachers ( OR =0.22, 95% CI =0.09 — 0.55), cooks ( OR = 0.09, 95% CI =0.04-0.23) and cleaners ( OR = 0.02, 95% CI =0.00-0.07) were far lower than school doctors ( P<0.05).
Conclusion The awareness of prevention and control of Norovirus outbreak among primary and middle school staffs in the Pearl River Delta region was needed to be improved. Valid implements, such as operation procedure, to build up prevention and control capability should be carried out that focus on specific job responsibilities.
【摘要】 目的 分析珠三角中小学校教职工诺如病毒感染暴发疫情防控知识及影响因素, 为开展学校诺如疫情防控 提供参考。 方法 采用多阶段定额随机抽样方法, 对珠三角 3 个地级市 48 所中小学校 320 名教职工开展诺如病毒基础知 识和感染暴发疫情防控知识知晓情况的问卷调查。 结果 珠三角中小学教职工对诺如病毒基础知识的知晓率为 35.37%, 暴发疫情防控知识的知晓率为 57.63%, 总知晓率为 48.42%。二元 Logistic 回归分析结果显示, 岗位是教职工诺如病毒感 染暴发疫情防控知识的影响因素, 教师 ( OR = 0.22, 95% CI = 0.09〜0.55)、厨工 ( OR = 0.09, 95% CI = 0.04〜0.23) 和保洁 ( OR = 0.02, 95% CI = 0.00〜0.07) 对诺如病毒暴发疫情防控知识的知晓率远低于校医 ( P 值均<0.05)。 结论 珠三角中小学校教 职工诺如病毒感染暴发疫情防控知识水平有待提高。学校需建立并执行具体防控流程, 明确教职工岗位职责和定位, 采取 理论结合实操的方式促使校医所掌握的知识向校内能力的转化。
