Actual surveys in kindergartens on SARS-CoV-2 infections are rare. At the beginning of the second pandemic wave, we screened 12 randomly selected kindergartens in Berlin, Germany. A total of 720 participants (pre-school children, staff and connected household members) were briefly examined and interviewed, and SARS-CoV-2 infections and anti-SARS-Cov-2 IgG antibodies were assessed. About a quarter of the participants showed common cold-resembling symptoms. However, no SARS-CoV-2 infection was detected, and only one childcare worker showed IgG seroreactivity. Against a backdrop of increased pandemic activity in the community, this cross-sectional study does not suggest that kindergartens are silent transmission reservoirs.
幼儿园内 SARS-CoV-2 感染的实际调查很少。在第二波疫情开始时，我们在德国柏林随机筛选了 12 所幼儿园。共有 720 名参与者（学龄前儿童、工作人员和相关家庭成员）接受了简短的检查和访谈，并评估了 SARS-CoV-2 感染和抗 SARS-CoV-2 IgG 抗体。约四分之一的参与者出现了类似感冒的常见症状。然而，没有检测到 SARS-CoV-2 感染，只有一名保育员显示 IgG 血清学反应性。在社区内大流行活动增加的背景下，这项横断面研究表明，幼儿园并非沉默的传播源。
