Should World Stop Shaking Hands After Covid? What Experts Say

One of the most striking takeaways from the Vladimir Putin and Joe Biden summit in Geneva this week was their fulsome handshake in front of the world's cameras -- a rare moment of physical human contact.

Banished at the start of the pandemic, the handshake is making something of a comeback, thanks to vaccinations and the lifting of social restrictions -- but "pressing the flesh" faces an uncertain future. More than speeches or communiques, one of the most striking takeaways from the Vladimir Putin and Joe Biden summit in Geneva this week was their fulsome handshake in front of the world's cameras -- a rare moment of physical human contact. A few days earlier, at the G7 summit in Cornwall, Biden and his fellow leaders were still elbow-bumping away, at outdoor events spaced six feet apart. Back in the United States, most Covid-19 restrictions have been lifted, and vaccinated citizens have been told they don't need masks -- even inside. Social distancing is largely a thing of the past, and unlimited domestic travel is back on.
