The new conventional wisdom seems to be that you raise your upper arm to cover your nose and mouth, a maneuver also known as the "Dracula sneeze."
And there is this: Last week, after Health and Human Services Secretary Kathleen Sebelius chided a reporter for sneezing into his hand at a news conference, conservative talker Rush Limbaugh pooh-poohed the practice. "Elitist snobs advising us to sneeze on our arms," Limbaugh called Sebelius and her ilk.
Limbaugh may have been joking -- and we must point out that sneezing into your shirt is different than wiping your nose with it. It's true, though, that Sebelius and public health officials advocate the Dracula sneeze.
Most schoolkids have already been indoctrinated. For many adults, though, it's a matter of re-teaching yourself -- or not.
If you have a cold and you sneeze into your hand, you're likely to touch things other people will touch. Then they could get what you have.
Says etiquette expert Lizzie Post: "We discovered a really valuable product. Its brand name is Kleenex, and they make pocket tissues."
