We investigated severe acute respiratory syndrome coronavirus 2 infections in primary schools, kindergartens, and nurseries in Germany. Of 3,169 oropharyngeal swab specimens, only 2 were positive by real-time reverse transcription PCR. Asymptomatic children attending these institutions do not appear to be driving the pandemic when appropriate infection control measures are used.
我们调查了德国的中小学、幼儿园和托儿所中严重急性呼吸综合征冠状病毒 2 型的感染情况。在 3169 份咽拭子标本中,仅有 2 份实时逆转录聚合酶链反应检测结果为阳性。在采取适当的感染控制措施时,这些机构中的无症状儿童似乎并未成为大流行的驱动因素。
