From China to Germany, here are some of the awkward interactions and alternate moves that have replaced physical greetings.

Health officials suggest a wave, a pat on the back or even just a look in the eye are safer alternatives than many traditional greetings.
German chancellor Angela Merkel was waved off by interior minister Horst Seehofer when she went in for a handshake at a meeting on migration Monday.
The pair were seen smiling immediately after, and Seehofer reportedly said he's stopped offering handshakes amid coronavirus.
COVID-19, the disease caused by the new coronavirus, is a respiratory illness spread primarily from person to person by people in close contact with one another -- about 6 feet. Adults over 65, young children, pregnant women and people with compromised immune systems from autoimmune diseases or chronic heart, lung or kidney conditions are at an increased risk of complications.
While it's inevitable for handshakes to transmit microorganisms through human-to-human contact, Nicky Milner, director of medical education at Anglia Ruskin University's School of Medicine, told ABC News that it's actually longer forms of contact that present a problem.
"On most occasions, this will cause no harm at all," she explained. "Greetings which have a longer contact time between people, or involve using a larger surface area, such as hand shaking, result in transmission of higher numbers of microorganisms. If any of these organisms have the ability to cause disease then our greetings can play a role in the transmission from person to person."
"It is important to recognize that we each have a role to play in limiting the spread of infections," she added.
Cultural shift
Although the World Health Organization has endorsed some of these optional greetings in a fairly tongue-in-cheek way, now is a good time to consider serious changes.
Milner said while it can be a challenge to have the public widely implement new greeting methods, especially if it requires a "shift in culture," there's a new range of possibilities "being observed and recommended."
"Being mindful that other people who you are greeting may not choose to shake hands and this is not considered to be rude," she said. "If a permanent ban on handshaking were to be introduced, I think that this would be very difficult to implement. However, raising awareness of our individual responsibility to wash our hands effectively is an important message to communicate to the members of the public."

"The culture of kissing is a common form of greeting in some countries. During widespread respiratory outbreaks, this is perhaps not an ideal form of greeting, and a handshake might be seen to be to be lower risk," Milner explained. "Although it is recognized that this is not always possible."
Best practices worldwide
"Raising awareness of the importance of effective handwashing is considered to be the most effective strategy when trying to minimize the spread of infections at all times," Milner said.
As the outbreak of the novel coronavirus continues, short-term changes like waving off handshake culture could prove effective.
