@gardengirl778 @EricTopol All students were tested weekly, so the cases would be identified throughout the classroom. Whether they considered people not within six feet to be instances of "potential transmission" I don't know (didn't read paper).
@gardengirl778 @EricTopol 所有学生每周都接受测试，因此将在整个课堂上识别病例。我不知道他们是否认为六英尺以内的人是“潜在传播”的实例（没有读过论文）。
