without masking in schools, an additional 70% of children could be infected with the coronavirus within three months.

翻译时成心把"additional"忽略掉的吧？

已经有一些孩子感染了，再感染当然是additional

带任务扣帽子就不要来

后一句说如果戴了口罩还是有40%的学生三个月之内被感染，这是说总学生数量的40%吧。

那没戴口罩的情况应该比40%严重吧

yes, thus the "additional 70%" is out of the whole population under discussion. The 1450s are trying to imply that 70% is out of the infected group, but that is unlikely given that "40% of elementary school students to be infected" even with masks.
