摘要

背景:2020-2021 年期间,由于 SARS-CoV-2 在普通人群中的传播率不断上升,法国当局决定继续开放学校,并对学生开展大规模筛查活动。在此,我们描述了这一策略对这一时期儿童和青少年中 SARS-COV-2 传播的影响:我们分析了法国国家公共卫生局提供的 2020-2021 学年 SARS-COV-2 监测数据以及国民教育部开展的校内筛查活动的结果:在整个学年中,0-17 岁儿童在确诊病例和受检者中所占比例不断上升,2021 年第 22 周(W),儿童和青少年在确诊病例中所占比例最高,达到 24%。2021 年第一学期(W3-W22),学校进行了超过 260 万次检测,学生中的阳性率为 0.32%。仅考虑有症状的病例,与 2020 年(W40-W48)相比,2021 年(W9-W17)儿童和青少年的发病率较高。在学校停课期间,发病率没有明显变化:2020-2021学年期间,儿童和青少年对病毒传播的贡献率较高,这似乎与阿尔法变体的出现有关,而与法国决定继续开放学校无关。考虑到学校关闭对儿童心理健康的负面影响,这些结果支持在采取适当控制措施的情况下继续开放学校的决定。

Keeping schools open during the emergence of the COVID-19 alpha variant: Impact on the circulation of SARS-CoV-2 among children during the 2020-2021 school year: Epidemiology of COVID-19 in children and adolescents during the 2020-2021 school year in France.

Background: During 2020-2021, in the context of increasing SARS-CoV-2 transmission in the general population, French authorities made the decision to keep schools open and set up massive screening campaigns for students. Here, we describe the impact of this strategy on the circulation of SARS-COV-2 among children and adolescents during this period.

Methods: We analyzed SARS-COV-2 surveillance data provided by the French National Public Health Agency for the 2020-2021 school year along with the results of school-based screening campaigns implemented by the Ministry of National Education.

Results: The proportion of 0-17-year-olds among confirmed cases and tested individuals increased throughout the school year, with children and adolescents reaching a maximum of 24 % of confirmed cases in 2021 week (W) 22. During the first semester of 2021 (W3-W22), >2.6 million tests were performed in schools, with a positivity rate of 0.32 % among students. Considering only symptomatic cases, higher incidence rates occurred among children and adolescents during the 2021 wave from W9 to W17 compared with that in 2020 from W40 to W48. The incidence rate did not significantly change following the school closure periods.

Conclusion: The higher contribution of children and adolescents to viral circulation during the 2020-2021 school year seems more related to the emergence of the alpha variant than to France's decision to keep schools open. Considering the negative impact of school closures on children's mental health, these results support the decision to keep schools open when accompanied by appropriate control measures.
