@michaelmina_lab @alexmeshkin To improve the situation you might layer risk-reducing measures in some way. Multiple layers of low risk reduction can equal a high reduction. But this becomes a comms problem. "Testing is [usefully] more safe" is different from "testing is useful as a layer".
@michaelmina_lab @alexmeshkin 为了改善这种情况，您可能会以某种方式分层降低风险措施。多层低风险降低可以等同于高风险降低。但这变成了一个通讯问题。 “测试[有用]更安全”不同于“测试作为一个层有用”。
