给跑步者，骑行者，步行者，徒步者的建议

给跑步者，骑行者，步行者，徒步者的建议

I like to run. And bike. And go for walks.

我喜欢跑步。和自行车。去散步。

Especially during the pandemic. It's a time I can almost forget about the novel coronavirus.

特别是在流行病期间。这是一个我几乎可以忘记新冠病毒的时刻。

But some people are trying to make me feel guilty about outdoor exercise.

但是有些人试图让我对户外运动感到内疚。

My own nephew said, "Uncle Marc, if you're infected and don't know it, you could be huffing and puffing out virus."

我自己的侄子说，“马克叔叔，如果你被感染了却不知道，你可能会气喘吁吁地呼出病毒。”

Does he have a point? I talked to a half-dozen experts to see about the risks of outdoor exercise for the exerciser and for others — and whether masks are helpful.

他说的有道理吗?我和六名专家交谈，了解户外运动对锻炼者和其他人的风险——以及口罩是否有用。

And let me clarify: I mean solo exercise. Going out shoulder to shoulder with a bunch of pals is not a good idea during a pandemic.

让我澄清一下:我指的是独自锻炼。在流行病期间，和一群朋友一起出去不是一个好主意。

First of all, my sources told me, studies all show that the biggest risk of catching the coronavirus is indoors, with face-to-face contact with others for a few minutes or more. Being outdoors for a solo activity is much lower risk. It appears that viral particles may not survive as long in the outdoor air as they do inside, although it's not certain whether wind, sun or other environmental factors are responsible.

首先，我的消息来源告诉我，研究都表明，感染冠状病毒的最大风险是在室内，与他人面对面接触几分钟或更长时间。独自在户外活动风险要低得多。病毒颗粒在室外空气中存活的时间可能不如在室内那么长，尽管还不确定是风、阳光还是其他环境因素造成的。

Here are some tips to keep your risk – and the risk to others — as minimal as possible.

这里有一些建议，可以让你以及对他人的风险，尽可能地降到最低。

First, there's the matter of the mask.

首先是口罩的问题。

The experts I spoke to all said wearing a mask is a good thing. Now you probably don't think you have the coronavirus if you feel good enough to exercise. But some people are asymptomatic – they never show symptoms – or presymptomatic – sick but not yet feeling it.

和我交谈过的专家都说戴口罩是件好事。如果你感觉良好，可以进行锻炼，你可能不会认为自己感染了冠状病毒。但有些人是无症状的——他们从未表现出症状或症状前症状——生病了但还没有感觉。

A mask will protect others by blocking respiratory droplets you breathe out that can carry viral particles. A mask with a tight weave (i.e., you can't see the sunlight through the fabric) and multiple layers may give you a measure of protection as well by preventing you from inhaling viral particles expelled by someone who's infectious.

口罩可以阻止你呼出的携带病毒的飞沫，从而保护他人。一个编织紧密的口罩(也就是说，你不能透过织物看到阳光)和多层口罩还可以防止你吸入传染性疾病患者排出的病毒颗粒，从而起到一定的保护作用。

Second, there's timing and location.

其次，还有时间和地点。

Pick a time and place where you won't likely be in close contact with people. So aim to get out when there aren't a lot of folks around. And look for routes that aren't hyper-crowded.

选择一个你不太可能与人有密切接触的时间和地点。所以，尽量在周围没有很多人的时候出去(锻炼)。寻找那些不太拥挤的路线。

Third, keep your hands to yourself. Don't touch "high-touch" areas where a lot of people might have put a hand down, such as a bench or a stair railing, says Jill Weatherhead, assistant professor of adult and pediatric infectious diseases at Baylor College of Medicine. It's possible that someone who's infected might have touched it and left behind droplets that can survive a little while on surfaces.

第三，管好你的手。贝勒医学院成人和儿童传染病助理教授吉尔·威瑟海德说，不要触碰“高接触”部位，比如长凳或楼梯扶手，很多人可能会把手放下来。被感染的人可能接触过它，留下了可以在表面存活一段时间的飞沫。
