我基本可以肯定你的老師沒有這麽教過你。可以想象拜登當年標準的做法也不是這樣。這種做法是近一二十年流行開來的

拜登沒有養成符合當前規範的習慣，也不是什麽難以原諒的事情。等你到了他那個年紀你就明白了。

Soon after the SARS and AI outbreaks a new maneuver was added to the definition of respiratory hygiene/cough etiquette: cover your mouth and nose with your arm, sleeve, or elbow. We were unable to find who was the first person to publish and describe this maneuver in a peer-reviewed journal, and we did not find any scientific study that supports its implementation.

 

We found that the Central Maine Medical Center, the Saint Mary’s Regional Medical Center in association with the Maine Medical Association released a video by Dr. Ben Lounsbury (Otorhinolounsburgology [ORL] Productions, 2006) that shows how to cough into your elbow. This seems to be one of the first documented explanations about how to perform the maneuver and the rational to use it [21].

 

However, this new maneuver is inconsistently recommended in written publications of global health authorities. USA-CDC does not include “cough in your arm/elbow” in its written recommendations, but it appears in the pictorial (poster) recommendation [18].
