打噴嚏時(shí)應(yīng)該捂住口鼻，但不是用手

When you feel a sneeze or a cough coming on, covering your mouth prevents the spread of infectious germs. You probably knew that.

當(dāng)你感覺(jué)快要打噴嚏或咳嗽的時(shí)候，要捂住嘴巴防止傳染性細(xì)菌的傳播。這一點(diǎn)你可能知道。

But the way you cover up also matters, and there are plenty of people who haven’t yet heard the consensus guidance of health officials: If no tissue is available, you should aim into your elbow, not your hand. Even if that means breaking a long-held habit.

但捂嘴的方式也很重要。很多人都沒(méi)有聽(tīng)說(shuō)過(guò)衛(wèi)生官員給出的指導(dǎo)意見(jiàn)：如果沒(méi)有紙巾，應(yīng)該對(duì)著臂彎打噴嚏或咳嗽，而不是手掌。即使這意味著你要打破自己長(zhǎng)期形成的習(xí)慣。

“If somebody sneezes into their hands, that creates an opportunity for those germs to be passed on to other people, or contaminate other objects that people touch,” said Dr. Vincent Hill, chief of the waterborne disease prevention branch of the Centers for Disease Control and Prevention.

“如果往手心里打噴嚏，就使得細(xì)菌有機(jī)會(huì)傳播給其他人，或是污染這個(gè)人碰過(guò)的其他物品，”疾病控制和預(yù)防中心(Centers for Disease Control and Prevention)水傳播疾病預(yù)防小組的負(fù)責(zé)人文森特·希爾博士(Dr. Vincent Hill)說(shuō)。

Germs are most commonly spread by the respiratory droplets emitted from sneezing and coughing. When they land on your hands, they’re transmitted to things like door knobs, elevator buttons and other surfaces the people around you are likely to also touch.

最常見(jiàn)的細(xì)菌傳播方式就是通過(guò)噴嚏和咳嗽時(shí)噴出的飛沫。飛沫落在手上，就會(huì)被傳遞到門(mén)把手、電梯按鈕等物體上，或是你身邊的人可能也會(huì)觸碰的其他表面上。

This isn’t just us nagging. Sneezing and coughing into your arm has become the standard suggestion of not just the C.D.C., but also organizations like the American Academy of Pediatrics and the American Public Health Association. Even the New York City subway system occasionally runs an announcement asking riders to “cough or sneeze into the bend of your arm or use a tissue.”

這并不是我們太煩人。向著臂彎打噴嚏和咳嗽不只成了疾病控制和預(yù)防中心的標(biāo)準(zhǔn)建議，也成了美國(guó)兒科醫(yī)生學(xué)會(huì)(American Academy of Pediatrics)和美國(guó)公共衛(wèi)生協(xié)會(huì)(American Public Health Association)等組織的標(biāo)準(zhǔn)建議。就連紐約市的地鐵系統(tǒng)都會(huì)時(shí)常播送廣播，要求乘客“向手臂彎曲處咳嗽、打噴嚏，或使用紙巾”。

You or your co-workers might be forgiven for not knowing that, since the suggestion is relatively new. The C.D.C. guidance has become official only in the last 10 to 15 years, Dr. Hill said.

這個(gè)提議相對(duì)較新，你和同事們對(duì)此并不了解也情有可原。希爾表示，疾病控制和預(yù)防中心的指南在最近的10到15年內(nèi)才成為官方指導(dǎo)。

Dr. Georges Benjamin, executive director of the American Public Health Association, said he began seeing the suggestion more prominently about 10 years ago.

美國(guó)公共衛(wèi)生協(xié)會(huì)執(zhí)行主任喬治·本杰明(Georges Benjamin)博士表示，大約在10年前他才開(kāi)始更加重視這些建議。

That means that adults may have missed the advice. Children, however, are frequently taught in school the proper way to cough or sneeze — sometimes referred to as the Dracula cough, since it makes you look like the count covering up with his cape.

這就意味著成年人可能錯(cuò)過(guò)了這些建議。不過(guò)孩子們經(jīng)常會(huì)在學(xué)校學(xué)習(xí)到正確的咳嗽或打噴嚏方式——它有時(shí)被稱為“德古拉咳嗽”(Dracula cough)，因?yàn)檫@會(huì)讓你看起來(lái)像是那位用斗篷遮住自己的伯爵。

Mary Anne Jackson, a professor of pediatrics at the University of Missouri-Kansas City School of Medicine, said the term “cough etiquette” first turned up in 2000, and she traced the suggestion to sneeze into your arm to 2003, when SARS fears were widespread. It gained further prominence in 2009, when the H1N1 swine flu pandemic struck the United States.

密蘇里-堪薩斯城大學(xué)(University of Missouri-Kansas City)醫(yī)學(xué)院的兒科教授瑪麗· 安妮·杰克遜(Mary Anne Jackson)表示，“咳嗽禮儀”這個(gè)詞首次出現(xiàn)在2000年，她說(shuō)，朝向手臂打噴嚏的建議可以追溯到“非典”(SARS)肆虐的2003年。到了2009年，H1N1豬流感疫情襲擊美國(guó)時(shí)，它進(jìn)一步得到了重視。

That year, Kathleen Sebelius, then the health and human services secretary, shamed Chuck Todd, an NBC journalist, for his sneezing etiquette at a White House press briefing. (Rush Limbaugh, the conservative radio host, later dismissed her advice as coming from “elitist snobs.”)

那年，時(shí)任衛(wèi)生和公眾服務(wù)部長(zhǎng)的凱瑟琳·西貝利厄斯(Kathleen Sebelius)還因?yàn)镹BC記者查克·托德(Chuck Todd)在白宮新聞發(fā)布會(huì)上的噴嚏禮儀把他羞辱了一番。(保守派電臺(tái)主持人拉什·林博[Rush Limbaugh]隨后將之斥為來(lái)自“虛榮精英派”的意見(jiàn)。)

To be clear, the maneuver doesn’t eliminate all risk, even if it’s the best tactic available. Studies have shown that even masks can’t prevent all droplets from becoming airborne, Dr. Jackson said.

要澄清的是，就算這個(gè)辦法是目前的最好手段，它也并不能消除所有風(fēng)險(xiǎn)。杰克遜表示，研究表明，即使是口罩也無(wú)法防止所有飛沫進(jìn)入空中。

But anything to reduce the amount of flying particles helps. And health officials keep coming back to a drum that can never be beat enough: Make sure you consistently wash your hands.

但任何能減少飛沫數(shù)量的辦法都是有好處的。衛(wèi)生官員反復(fù)強(qiáng)調(diào)的這個(gè)觀點(diǎn)再怎么重復(fù)都不為過(guò)：保證你經(jīng)常洗手。

“Hand washing is one of the most important things people can do to keep healthy,” Dr. Hill said.
