The British Olympic chief medical officer has advised athletes not to shake hands at the 2012 London Games, for fear of picking up a bug which could end their medal dreams.
The Daily Mail reported that Dr Ian McCurdie is concerned about the 'stressful environment' that the Olympics creates and noted that a mild bug contracted under these conditions could easily knock an athlete off their stride.
Asked whether this means shaking hands should be off-limits, he said: "I think, within reason, yes. That is not such a bad thing to advise.
"The difficulty is when you have got a line of about 20 people you've never met before who you have got to shake hands with.
"Within reason if you do and have to shake hands with people, so long as you understand regular handwashing and/or using hand foam can help reduce the risk."
