@michaelmina_lab Very few people are willing to voluntarily disrupt their travel by the time they've already arrived at the airport. They won't take the test, or will take it but quietly throw away the positive test because they "feel fine".
@michaelmina_实验室很少有人愿意在抵达机场之前自愿中断旅行。他们不会接受测试，或者会接受测试，但会悄悄地扔掉阳性测试，因为他们“感觉很好”。
