Don’t Fear Graduation Handshakes
握個手沒什么大不了

It’s graduation season. And some scientists got to wondering whether the folks who shake hundreds of hands while passing out diplomas run the risk of coming away with a fistful of infectious microbes, such as Staphylococcus aureus. Good news—turns out the risk of being passed a disease-causing bacterium while pressing the flesh is pretty remote. That’s according to a study in the Journal of School Nursing. [David Bishai et al., "Quantifying School Officials’ Exposure to Bacterial Pathogens at Graduation Ceremonies Using Repeated Observational Measures"]
轉(zhuǎn)眼畢業(yè)季。一些科學(xué)家萌生了這樣的猜想，學(xué)校領(lǐng)導(dǎo)們發(fā)畢業(yè)文憑的時候要跟那么多學(xué)生握手，會不會感染金黃色葡萄球菌這類微生物什么的。放心吧——研究結(jié)果表明，握個手沒那么容易感染致病菌的。這項研究結(jié)果刊登在《學(xué)校護(hù)理雜志》上。

The researchers swabbed the palms of 14 school officials before and after graduation. They found that before the ceremony, and even after a slathering of sanitizer, hands were home to plenty of nonharmful bacteria. On the infectious scorecard, one dean brought Staph aureus to a commencement. Two others at a different ceremony walked away with it. And one of those samples came from a left hand, which didn’t participate in any of the meeting or greeting. So the math says that of more than 5,000 handshakes, just one may have passed along something less welcome than a sheepskin.
研究人員在畢業(yè)典禮前后采集了14位校領(lǐng)導(dǎo)手掌表面細(xì)菌樣本。他們發(fā)現(xiàn)，畢業(yè)典禮之前，就算是抹上厚厚 一層消毒劑，領(lǐng)導(dǎo)們的手上都布滿了無害細(xì)菌。一位校領(lǐng)導(dǎo)手持帶有金黃色葡萄球菌的標(biāo)記卡參加某畢業(yè)典禮，后來研究人員在出席別的典禮的兩個人手上發(fā)現(xiàn)了標(biāo) 記細(xì)菌，其中一個還是在左手上發(fā)現(xiàn)的，握手什么的根本用不著左手。計算可得，握5000次手才有一個人有機(jī)會“中獎”。

So if you’re graduating this spring, feel free to shake hands. While you wonder if the last person who wore that robe had anything contagious.
要是這個春天你也即將畢業(yè)，那就盡情握手吧～咦？剛剛那個那么熱的天還長衣長褲？該不會攜帶了什么病菌吧。。。。
