DAVID: Thank you, Dr Lio. The next question is, Is it safe to be in an enclosed space and take public transportation? How can we protect ourselves if we must take public transportation?
DR. LIO: You can minimize risk, again, by social distancing rules. For example, while taking the train, make sure there are a couple seats between you and other people. Be careful of what you are touching on the train. Try not to touch anything with your hands. If you’re in an even smaller space like an elevator, that can be trickier. If it’s a small elevator, with more than two people, that might be too much, so I would wait for the next elevator. If it’s a bigger elevator, sometimes you can have like four people. They could stand in all the corners.
But it definitely is a bit of a risk just going outside. I would suggest if you’re at higher risk for getting COVID and for getting severe complications—for example, if you have uncontrolled HIV, if you have cancer, if you’re on any kind of medicines that suppresses your immune system—you should be staying home as much as possible. If there are other people in your family, relatives that can help you out by going out for groceries, then have them do that, but stay home. So yes, you can reduce your risk, but if you are at high risk, don’t go out at all.

大卫：谢谢您，刘医生。下一个问题是，在封闭的空间里乘坐公共交通是否安全？如果必须乘坐公共交通，应该如何保护自己？
刘医生：你可以同样通过保持社交距离规则降低感染的风险。比如，在坐地铁时，确保你和其他人之间有几个座位的空间。注意你在车厢内上用手触碰的东西，尽量不要用手碰任何东西。
更加棘手的情况是在怎么在更狭小的空间里保护自己，比如电梯里。如果在很小的电梯里站了至少两个人，那可能就太密集了。我建议你等下一趟电梯。如果电梯里空间比较大，有时可以四个人同时乘坐电梯，那么可以每个人各站在一个角落。
刘医生：只要是外出，就一定有风险的。如果你出现新冠严重并发症的风险较高，比如，如果你患有不受控制的 HIV，或者患有癌症，或者正在服用任何一种抑制免疫系统的药物，那么你应该尽可能留在家中。如果你的家里有亲属可以替你外出采购生活必需品，那么就拜托他们替你去，自己不要出门。总之，有办法在封闭空间中降低传染的风险，但是如果你是高风险人群，那就根本不要出门。
