F: I mean if you wear a face mask, it will reduce the risk to spread the virus.
我的意思是，如果你戴上口罩，它将减少传播病毒的风险。
D: Sure, but the rest of your body's surface can still spread it, only isolation will prevent the spread.
这没错。但是你身体的其余部分仍然可以传播病毒，只有隔离才能阻止病毒扩散。
D: In addition, if all healthy people wear masks, it will cause masks in short supply, so that people like us in hospitals who actually need them every day will lack masks.
D: If you don't wear a mask properly you're also spreading the virus.
还有如果你戴口罩的方式不正确，那么你照样也会传播病毒。
F: You learned from the western medical science, I judge by facts and logic.
你的看法来自西方医学科学，我的判断基于事实和逻辑推理。
D: It doesn't make sense. It's airborne. Your mask is not tight. You have to change the mask every few hours which most people don't do. The spread of a lot of viruses is from virus surviving on hard surfaces.
D: You aren't even logical. You keep saying a mask will help you. It's airborne virus. Mask is not sealed. Air goes into mask, because a mask has holes, it's not sealed against your face.
D: If you can breathe with a mask on, you can breathe in the virus. As simple as that.
如果你可以戴口罩呼吸，你就可以吸入病毒。就这么简单的道理。
F: But, it reduces the chance of virus going into your mouth and nose. A medical face mask can filter very tiny particles. Understand?
但是，口罩减少了病毒进入您的口腔和鼻子的机会。医用口罩可以过滤非常小的颗粒。知道吗？
D: No, oh my god you missed a lot of hygiene knowledge. That's not the only places it enters your body. How do you eat? With your hands. How do you see, with your eyes. Is your mask covering those areas? No.
D: There are many different medical masks, they do not filter virus, Dad, don't forget I work in a hospital. Why are you trying to be an expert in this topic and spread false information. In order to wear a N95 mask properly you need to be mask fitted.
D: In the hospital we are all mask fitted with a personalized size to our face.
在医院里，我们所有的口罩都配合个性化的脸部尺寸。
D: You are not mask fitted.
你的口罩没有这种配套过程。
D: When it's properly fitted, it's very hard to breathe. You can't wear it for more than an hour because you will not get enough oxygen. That's how tight the mask is. You can't breathe and need to change to new mask.
