In the last business suspension request, the stores somehow managed to avoid closing down completely, but we don't know what would happen if another business suspension request is issued next time.
☆「まぬがれた」は"managed to avoid"という部分になります。
"In the last business suspension request"＝「前回の休業要請では」
"the stores somehow managed to avoid closing down completely"=「お店は何とか完全に閉店することを免れた」
"but we don't know what would happen"＝「でも私たちは何が起こるか分からない」
"if another business suspension request is issued next time."=「もし次回、また休業要請がされたら」
