When it comes to transmission of the swine flu virus, some greeting customs are better than others.
The Japanese bow is perhaps the most antiseptic of greetings. At the other end of the spectrum is la bise, the French custom of giving multiple light kisses on the cheek in greeting or parting.
And even though it flies in the face of French tradition, France's Ministry of Health is advising people to stop kissing for fear of spreading swine flu.
Meanwhile, the Association of Corporate Travel Executives is advising business travelers to temporarily eschew handshakes.
The public has been told it's better for people to sneeze or cough into a sleeve than their hand, but business travelers heading to a meeting don’t want to risk soiling that nice suit, ACTE reasons.
"A random polling of ACTE members has revealed it would be easier to drop the traditional handshake for the duration of the health crisis -- should one develop -- as opposed to sneezing or coughing into a sleeve," said Susan Gurley, ACTE’s executive director.
