Briefly before the first peak of the COVID-19 pandemic in Berlin, Germany, schools closed in mid-March 2020. Following re-opening, schools resumed operation at a reduced level for nine weeks. During this phase, we aimed at assessing, among students and teachers, infection status, symptoms, individual behaviour, and institutional infection prevention measures. Twenty-four primary and secondary school classes, randomly selected across Berlin, were examined. Oro-nasopharyngeal swabs and capillary blood samples were collected to determine SARS-CoV-2 infection (PCR) and specific IgG (ELISA), respectively. Medical history, household characteristics, leisure activities, fear of infection, risk perception, hand hygiene, facemask wearing, and institutional preventive measures were assessed. Descriptive analysis was performed. Among 535 participants (385 students, 150 staff), one teenager was found to be infected with SARS-CoV-2 (0.2%), and seven individuals exhibited specific IgG (1.3%). Compared to pre-pandemic times, screen time (e.g., TV, gaming, social media) increased, and the majority of primary school students reported reduced physical activity (42.2%). Fear of infection and risk perception were relatively low, acceptance of adapted health behaviors was high. In this post-lockdown period of low SARS-CoV-2 incidence in Berlin, individual and school-level infection prevention measures were largely adhered to. Nevertheless, vigilance and continued preventive measures are essential to cope with future pandemic activity.
在德国柏林 COVID-19 大流行的第一个高峰之前不久，学校于 2020 年 3 月中旬关闭。重新开放后，学校在减少人员的情况下运作了九周。在此期间，我们旨在评估学生和教师的感染状况、症状、个人行为以及机构感染预防措施。我们在柏林随机选择了 24 个小学和中学班级进行检查。采集口咽拭子和毛细血管血样，分别用于确定 SARS-CoV-2 感染（PCR）和特异性 IgG（ELISA）。评估了医疗史、家庭特征、休闲活动、对感染的恐惧、风险感知、手部卫生、戴口罩以及机构预防措施。进行了描述性分析。在 535 名参与者（385 名学生，150 名教职员工）中，发现一名青少年感染了 SARS-CoV-2（0.2%），有 7 人表现出特异性 IgG（1.3%）。与大流行前相比，屏幕时间（例如电视、游戏、社交媒体）增加了，大多数小学生报告的体育活动减少（42.2%）。对感染的恐惧和风险感知相对较低，对适应性健康行为的接受度较高。在柏林 SARS-CoV-2 发病率较低的这个封锁后时期，个人和学校层面的感染预防措施得到了广泛遵守。然而，保持警惕并继续采取预防措施对于应对未来的大流行活动至关重要。
