@JusDayDa @Bob_Wachter It's obviously not the (no longer working) protections that are keeping schools open, it is a policy willingness to have an explosion in the number of infections. And no, the place where kids spend most of their time in a congregate indoor setting isn't "the safest place".
@JusDayDa@Bob_Wachter让学校继续开放的显然不是（不再有效的）保护措施，而是让感染人数激增的政策意愿。不，孩子们大部分时间在室内集合的地方并不是“最安全的地方”。
