(NBC News) - Our society dictates that when meeting someone new the polite thing to do is shake their hand.
Now new research suggests the common handshake is great, if you want to make someone sick.
Infectious disease experts have a better and safer solution.
"Rather than replace the handshake with something else that has contact, probably the better approach to keep patients safe is really not to do it at all." said Dr. Mary Lou Manning from Association for Professionals in Infection Control and Epidemiology.
