    The Centers for Disease Control and Prevention describes social distancing as "remaining out of congregate settings, avoiding mass gatherings and maintaining distance (approximately 6 feet or 2 meters) from others when possible."

    Why? When someone coughs or sneezes, small drops of liquid spray from their nose or mouth. If you're standing too close, you can breathe in the droplets, which may contain the coronavirus if the person coughing is infected, according to the World Health Organization.
    為什么? 當某人咳嗽或打噴嚏時,會從他們的鼻子或嘴里噴出一小滴飛沫。 根據世界衛生組織的說法,如果您站得太近,則可以吸入飛沫,如果咳嗽的人已經被感染,飛沫中則可能含有冠狀病毒。

    The "6 feet of distance" rule comes from studies of respiratory physiology, said Dr. William Schaffner, infectious disease expert at Vanderbilt University.
    范德比爾特大學(Vanderbilt University)傳染病專家威廉·沙夫納(William Schaffner)博士說,“ 6英尺遠”的要求來自對呼吸生理學的研究。

    "Without a cough or a sneeze, if we exhale, the distance 3 to 6 feet from each other is called the breathing zone. And it's in that kind of volume of air that what I exhale begins to mix with the air that's already in the room," Schaffner said. "So if you're standing within 3 to 6 feet of me, you may well inhale some of what I exhale. And of course if I have the virus, what I'm exhaling microscopically contains the virus."
    “沒有咳嗽或打噴嚏,如果我們在呼氣,彼此之間的3到6英尺的距離則稱為呼吸區。而我呼出的氣體與房間中在這個距離內的已經存在的空氣混合,”沙夫納說。 “因此,如果您站在我3至6英尺的范圍內,您可能會吸入一些我呼出的東西。當然,如果我感染了這種病毒,那么我從微觀上我呼出的就含有這種病毒。”

    If you're finding it hard to estimate what exactly 6 feet looks like, we've got a list of animals, people and things you can keep in mind to help you judge the appropriate distance you should keep from other people.

    Two Golden Retrievers standing nose to tail
    The average Golden Retriever has a body length of 37 to 42 inches. Two of these dogs should amount to just over 72 inches, or 6 feet.
    A man wearing a top hat
    A man of average height stands at 5 feet 9 inches tall -- if that man wears a President Abraham Lincoln-esque top hat, he'd be just over the distance we're advised to keep from others.
    An average sedan
    Think of the width of your car when trying to gauge an appropriate distance -- an average large sedan is a little more than 6 feet wide.

    A sofa
    A standard three-seat sofa can be up to 6 feet long -- which means that you and the person sitting on the other end of it probably aren't far away enough from each other.
    The length of a mattress
    The lengths of full- and twin-size beds are about 6.2 feet from top to bottom.
    Two adult cats
    Cat lovers may find it easy to commit this comparison to memory: Two male adult cats, at 35 inches each from their heads to the tips of their tails, can amount to nearly 72 inches.

    A door
    A door should be relatively easy to find when questioning whether you and your friend should move farther apart. Six feet is a little shorter than the average modern door, which runs from 78 to 80 inches.
