Abstract

We report epidemiological investigations of transmission of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in 41 classes of 36 schools in Reggio Emilia province, northern Italy, from their reopening on 1 September to 15 October 2020. The overall secondary case attack rate was 3.2%, reaching 6.6% in middle and high schools. More timely isolation and testing of classmates could be effective in reducing virus transmission in this setting.

摘要

我们报告了对 2020 年 9 月 1 日至 10 月 15 日意大利北部艾米利亚-罗马涅地区 36 所学校 41 个班级中严重急性呼吸综合征冠状病毒 2（SARS-CoV-2）传播的流行病学调查。总体二级病例发病率为 3.2%，中学和高中达到 6.6%。在这种情况下，更及时地对同学进行隔离和检测可能有助于减少病毒传播。
