Schools in the Republic of Ireland reopened to students and staff in late August 2020. We sought to determine the test positivity rate of close contacts of cases of coronavirus disease 2019 (COVID-19) in schools during the first half-term of the 2020/2021 academic year.
National-level data from the schools' testing pathway were interrogated to determine the positivity rate of close contacts of cases of COVID-19 in Irish primary, postprimary and special schools during the first half-term of 2020/2021 academic year. The positivity rates among adult and child close contacts were compared and the proportion of national cases of COVID-19 who were aged 4-18 years during the observation period was calculated to assess whether this proportion increased after schools reopened.
Of all, 15,533 adult and child close contacts were tested for COVID-19 through the schools' testing pathway during the first half-term of the 2020/2021 academic year. Three hundred and ninety-nine close contacts tested positive, indicating a positivity rate of 2.6% (95% confidence interval: 2.3-2.8%). The positivity rates of child and adult close contacts were similarly low (2.6% vs 2.7%, P = 0.7). The proportion of all national cases of COVID-19 who were aged 4-18 years did not increase during the first half-term of the 2020/2021 school year.
The low positivity rate of close contacts of cases of COVID-19 in schools indicate that transmission of COVID-19 in Irish schools during the first half-term of the 2020/2021 academic year was low. These findings support policies to keep schools open during the pandemic.
2020 年 8 月下旬,爱尔兰共和国的学校重新向学生和教职员工开放。我们试图确定 2020/2021 学年第一学期期间学校内 2019 年冠状病毒病(COVID-19)病例密切接触者的检测阳性率。
通过学校检测途径的国家层面数据,确定 2020/2021 学年第一学期爱尔兰小学、中学和特殊学校 COVID-19 病例密切接触者的阳性率。比较成人和儿童密切接触者的阳性率,并计算观察期间 COVID-19 国家病例中 4-18 岁年龄组的比例,以评估学校重新开放后该比例是否增加。
在 2020/2021 学年第一学期,共有 15533 名成人和儿童密切接触者通过学校检测途径接受了 COVID-19 检测。399 名密切接触者检测呈阳性,阳性率为 2.6%(95%置信区间:2.3-2.8%)。儿童和成人密切接触者的阳性率也很低(2.6%比 2.7%,P=0.7)。在 2020/2021 学年第一学期,所有 COVID-19 国家病例中年龄在 4-18 岁的比例没有增加。
学校内 COVID-19 病例密切接触者的低阳性率表明,2020/2021 学年第一学期期间爱尔兰学校 COVID-19 的传播率较低。这些发现支持在大流行期间保持学校开放的政策。
