@canntrader @sdbaral @ezralevant And if the latter don't isolate, then they increase crowding in the stores and businesses being shared by those lower middle class/working class people. More crowding = EVEN MORE exposure.
You have to separate pre-existing risk due to job function. Lockdowns didn't cause that.
@canntrader@sdbaral@ezralevant，如果后者不孤立，那么他们会增加中下层/工人阶级共享的商店和企业的拥挤。更多拥挤=更多暴露。
由于工作职能，您必须分离先前存在的风险。封锁不是原因。
